Brass poly compression fittings are components used in piping to change direction, branch, pipe diameter or connect two pipes together. In galvanized pipe piping, the most common poly-compression fittings are bush, knee, tee, brain, nail nut, transform and cap, whose material must be galvanized steel according to national building regulations. ) Or hammered cast iron. The following is a list of the latest compression brass fitting lists.
What is the purpose of poly compression fittings?
A poly compression fitting is a type of coupling used to connect two pipes to a fixture or valve. It consists of three parts… the compression nut, the compression ring, and the compression reducing coupler seat. As you can see in the diagram at the left, the nut is slid onto the pipe, followed by the compression ring.
The pipe is slid into the fitting (in this case a toilet shutoff valve) and the nut is tightened down. As the nut is tightened, the poly compression ring is pressed into the seat, causing it to compress against the pipe and the compression nut, providing a watertight connection.
Though the primary advantage of poly compression fittings may seem to be in their ease of assembly, their real advantage is in their ease of disassembly! If you look throughout your home, you will see that the use of poly compression fittings is generally limited to appliances and fixtures that will… given enough time, normal use, and wild beatings with a hairbrush… wear out and need to be replaced. Look under your bathroom vanities, behind your toilets, under your dishwasher or behind your refrigerator… and you will see poly compression fittings in flagrante delicto!
In fact, the now ubiquitous use of poly comperession fittings in homes conveniently corresponds with the advent of do-it-yourself , user-friendly fixtures and appliances. After all, if you want to sell faucets to folks with limited skills, you want to make their installation as painless as possible. Ergo, poly compression fittings!
But poly compression fittings have a dark side, and may leak if not used properly. Here are my rules for the use of poly compression fittings. If you don’t follow them, you may regret it!
If you look critically at poly compression fittings, one thing is apparent… they are designed to inhibit the movement of the pipe outward from the fitting. However, they do a poor job preventing the pipe from turning within the fitting. To visualize this, take the example of the connection for a refrigerator icemaker.
Typically, a poly compression fitting is used to connect copper tubing to the icemaker. To prevent the thin 1/4″ tubing from kinking or bending when the refrigerator is pushed back to the wall, an excess of tubing is normally “coiled” behind the refrigerator. This acts like a spring, expanding when the refrigerator is pulled out, and compressing when the fridge is pushed back.
A problem arises if the tubing is not solidly clamped to the rear of the refrigerator. Without this clamping, the tubing creates a rotational stress on the poly compression fitting as the fridge is moved, and can over time cause the tubing to rotate within the fitting, or even loosen the compression nut, causing a “stealth” leak behind the refrigerator. This can be a particularly nasty leak, because it can soak the floor with not evidence until the damage is severe… or until friendly, family-minded carpenter ants find the nice, damp wood!
Another use for poly compression fittings that is a qualified NO is lengthening of pipes using a straight or angled double poly compression fitting (left). About the only time this is acceptable is under a sink, where there is no movement or stress. If there is even a chance that the compression connection will be subjected to rotational movement or impact of any kind, it is better to use a solder, or “sweat”, connection instead.
Each poly compression fitting is a little different in the way it orients itself while tightening… yet sometimes a fitting can be reused. Refrigerator icemaker connections and dishwasher connections are two that come to mind. If you decide to try to make a connection using the existing permanently attached ring and nut, be sure to lubricate the ring and the threads on the compression nut. You will improve your chance of a successful seal..
You can not remove a poly compression ring from tubing once it has been used. If you can’t get a leakproof connection, the tubing behind the ring will have to be cut, and a new ring installed. Though the compression nuts can often be reused, I would recommend against it because the old nut may be slightly deformed and lessen the quality of the new connection.

Black polyethylene pipe compression fittings at cheap price
PE compression fittings are the type of compression fittings for PE 80 and PE 100 brands. Compression fittings are made of a polypropylene copolymer for casting.
Polyethylene compression fittings with internal and external threads are made in various forms:
compression fittings, tee compression, bending compression and saddle compression bends, compression bends and flange compression fittings. PND compression fittings are produced with a diameter of 16 mm to 110 mm and a working pressure of 10 to 16 atmospheres (bar):
for a diameter of 16 to 63 mm and 16 bar, for a diameter of 75 to 110 mm and 12.5 bar. PND compression fittings are connected to PE pipes by means of a compression loop, which is compressed into a tube. Compression joints for threaded poly pipe fittings are a decay scheme consisting of modular components.
Areas of application of PND compression fittings for connecting and installing PE80 and PE100 grade PE pipes in shifting locations:
rotations and branches, in pipeline diameter changing locations, at joints with Pipe joints, as well as for the transfer of PE pipes from other materials. Compression fittings are used to install and repair PE80 and PE100 grade pipes used in drinking water and technical water supply systems (drinking water and feed pipelines, industrial water in irrigation systems, etc.).
Sealed cables are used. These joints can also be used in any pipeline with the workplace, in which case the chemical resistance of the compression joints is guaranteed. Polyethylene compression fittings are widely used in automatic irrigation systems. The use of compression fittings made of low-pressure polyethylene ensures full thickness between mounted components. Installing small diameter PND poly compression fittings manually without the use of special tools Large diameter is performed using special compression wrench. Compression fittings can be used for PE PE tubes under any weather conditions and freezing temperatures. Compression should be indoors and protected from direct sunlight.
PND Compression Fittings Compression fittings for polyethylene pipes consist of five elements:
1. The bead cap is made of a polypropylene copolymer, intended for removal and displacement, with an internal thread and outer grooves for orientation The screw is comfortable.
2. The sealing ring is made of polyoxymethylene, prevents the movement and extrusion of the stationary tube, and also prevents spontaneous screws.
3. The press-made sleeve is made of polypropylene copolymer, removes the gasket to a stable position and restricts compression and deformation of the end tube.
4. The sealing ring gasket is made of nitrile rubber, providing reliable tightness to the pipe even when bending.
5. The plasson poly pipe fittings chamber, made of polypropylene copolymer, has a trapezoidal thread for the nut and stop tube insertion.
Key Benefits of Easy Installation:
Installation is quick and unprocessed because the connections are ready to install and require no special skills or additional equipment. Ease of repair: When repairing compression joints, special skills, extras and welding equipment are not required, only a plastic or metal compression wrench is required and the repair itself is done by replacing the internal components of the compression joint.
Multi-Assemblage Separation: Assembling and separating compression joints for HDPE pipes can be performed up to 10 times over and over. Corrosion resistance:
No metal elements in PND compression joints Hygiene:
All parts of the compression joints are made of materials that are suitable for transporting drinking water and food liquids Connecting with other elements:
Compression joints PNDs have standard internal and external threads, so prefabricated elements can be mounted to connect pipes and fittings of different materials.
What is the cheapest plastic pipe and fitting?
Currently, both natural and synthetic plastics are widely used in industrial joints. Each plastic has different properties depending on its properties and density. Synthetic plastics include polyurethane, PVC, polyamide (nylon) and MDPE, LDP (E), LLDPE, PFTE (polyethylene). Plastic is a lightweight material that does not rust and does not rot, so it is suitable for use underground or outdoors. It is easy to maintain and very flexible compared to metal pipes. It has low thermal and electrical conductivity, so it is resistant to heat.
Since these elements do not contain water-soluble elements, plastics are an excellent material for water storage and transportation, especially electricity and drinking water. In addition, due to its ability to withstand heat, pipes and industrial joints are widely used in the water and wastewater industries. ABS fittings, blue line poly pipe fittings, warheads and plugs, nuts, hoses and pipes, and pipe cover are all commonly used industrial products made of plastic. Plastic pipes and fittings are very popular because they are cheap and easy to cut, but also because of the easy connection using hdpe to pvc compression fitting solvent cement. A properly cemented joint is permanent and is both aeration and pond and takes less than a minute.
Brass Compression Fittings For Flexible Polyethylene Tube
Rice is an alloy of copper and zinc, sometimes containing lead. The metal is very versatile, but is generally more expensive than other materials and is more easily recyclable. Industrial brass fittings are durable and durable.
They are long lasting and survive better in hard conditions than other materials. They are resistant to heat and cold stress and do not rust against corrosive materials. Rice is used in the manufacture of industrial pipes and brass fittings in the plumbing industry because it can withstand high temperatures. Valves – Including compression fittings, valve valves, pipe fittings are some of the items used in the industry to manufacture rice.
Flexible industrial bras fittings:
A hot-rolled brass carbon alloy is often used instead of steel and is cheaper than steel. Flexible brass is a very strong metal with high wear resistance and shock resistance and also has high heat and pressure resistance.
Weldable brass for components in the transportation industry and in the construction of railways and heating, cooling and safety systems, the gas industry and solar heating systems, as well as in the manufacture and design of industrial fittings such as black and galvanized steel pipe fittings, black wire and Galvanized and nut, pipe accessories are also used in galvanized products hdpe mechanical saddle.
What are the advantages of brass compression fitting?
One of the most used accessories in the industry are brass accessories, which are manufactured and sold in large quantities due to their wide use and great benefits. These compounds are classified into different types according to the type of application, composition and size. These applications are classified into brass, water, gas and compressed air connection types.
These connections determine the type of connection that flows to the lines, the type of lines and pipes and the type of connection according to the thickness structure.
For example, brass fittings are available in two general versions:
high pressure and high pressure. When the pressure is high in the transmission lines, the high pressure type is used. High pressure brass fittings benefit greatly from the oil and gas industry. Due to its structure, they cite all types of brass knees, brass bushings, brass variations, three-way brass, square brass, brass hinge and brass, nipple and brass gear, round left hinge and brass. ۔
Characteristics of the rice used in these compounds:
Rice is the most used compound due to its physical properties. The melting temperature of rice is very high and metal, which is a mixture of copper, zinc and other elements with low components, has a high mechanical and thermal resistance. Later it is used than other metals and is resistant to corrosion. This type of metal is also not moldy and opaque and is very suitable for hitting the construction. Hot and cold metal formulations are excellent and, therefore, are used in the manufacture of accessories.
