What are the names of PVC fittings?

PVC pipe systems are widely used in water supply systems, drainage systems, sewage treatment systems, and in agricultural irrigation fields.

In short, whenever it comes to the transportation of liquids, PVC pipe fittings are needed.

PVC pipe fittings are mainly used in conjunction with PVC pipes. In order to adapt to different installation environments, different shapes and types of PVC pipe fittings are required.

The main and most common PVC Fittings in PVC piping systems are Couplings, Elbows, Tees, Reducers Couplings, Crosses, Union, Adapters, Saddle Clamp, Flange, Caps, Plugs, Bushings, and Valves.

PVC Coupling

PVC Coupling is one of the simplest, most common, and most used pipe fittings. It is mainly used to connect two sections of equal-diameter pipes.

PVC Elbow

PVC elbow is a pipe fitting that joins two lengths of PVC pipe together at a fixed angle. When the direction of the pipe needs to be adjusted during the laying process, then the PVC elbow comes in handy!
According to the different extension directions of the pipeline, elbows are divided into 90-degree elbows, 45-degree elbows, and 22.5-degree elbows according to different angles.

PVC Tee

PVC Tee has three ends. Both ends are straight and one end is 90 degrees vertical. It allows fluids to be split or pooled in two directions.
Tee can be divided into equal diameter tee and reducing tee according to the end size.

PVC TEE includes PVC equal diameter tee, different diameter tee adn Y tee .

PVC Reducer

PVC reducers are direct and can connect two sections of pipes with different sizes together. When reducing pipes are needed to reduce flow in the pipeline system, PVC reducers must be used directly

PVC Cross

PVC Cross are suitable for complex piping systems. It has four connecting parts, one end is the water inlet and the other three ends are the water outlets. There are two styles of PVC crosses, one is distributed perpendicularly to each other, and the other is distributed at a 45-degree angle.

PVC cross can connect four pipes and change the direction of the fluid in the pipes.

PVC Union

PVC unions function similarly to PVC connectors. It connects two sections of equal diameter pipes together. One of its biggest features is that it is detachable! It has two ends and can be separated. When a pipe ages, breaks, or needs to be replaced, there is no need to cut the pipe or replace the entire pipe. You only need to remove the PVC connector and replace the damaged part. Due to this characteristic of PVC union, it is often used in places where pipe systems are prone to damage, such as swimming pools, sewage treatment or industrial pipeline systems.

PVC Adpaters

PVC adapters are another form of PVC connectors. It has two ends, one end is connected to the pipeline with glue, and the other end is used to connect other testing equipment in the pipeline, such as pressure gauges, flow meters, thermometers, etc. PVC adapters are available in both external and internal threads.

PVC Saddle Clamp

PVC saddles can be used to add new branches to existing pipes. Close the pipe, drill holes in the pipe, clamp the pipe with the saddle, connect and fix it with screws, and finally insert the new pipe and pipe fittings into the saddle.

PVC Flange

PVC flange is used to connect valves or pumps and pressure vessels to pipes necessary for connection. Flanges are connected by bolts, and sealing is usually accomplished by using gaskets or other methods. PVC flanges include: integrated flange, split flange and blind flange.

PVC End Cap

The shape of the PVC end cap is very simple, it is a round cap. It has two connection methods: threaded connection or glue connection, and is mainly used for capping the ends of pipes.
When the end of the pipeline is not used or does not need to be connected to other pipelines, or when the pipeline needs to be temporarily stopped due to maintenance or construction, PVC end caps can be used to seal the pipeline. Usually during pipeline transportation, PVC end caps (without glue) are also used to protect the two sections of the pipeline to avoid damage during transportation.

PVC Plugs

The function of PVC plugs is the same as that of PVC end caps, which are to seal the end of the pipe.
The biggest difference between the two is how they are used. The PVC end cap is placed on the outside of the pipe end, while the PVC plug is inserted on the inside of the pipe end. PVC plugs have external threads, and PVC end caps have internal threads.

PVC Bushing

The PVC Bushing is used in pipelines to connect two pipes of different sizes. They have a socket connector on the outside and a socket connector on the inside. A socket x socket coupler is required to connect the socket side of the fitting to the existing pipe.

A comprehensive guide to CPVC and PVC pipes

CPVC is a variation of PVC derived from the chlorination of PVC, in which additional chlorine atoms are chemically bonded to the polymer chain. This chlorination process increases the chlorine content of the material. CPVC has stronger high-temperature resistance, pressure resistance, and corrosion resistance than PVC.
