A beginner’s guide to PVC fittings description and applications

PVC is a white plastic pipe and it is commonly used for drainage and plumbing purposes. PVC is an abbreviation that stands for Poly Vinyl Chloride and it has become a common replacement for metal piping. PVC joints are molded into various shapes to create a fitting, valves, pipe, and other liquid handling supplies. PVC is the most widely used plastic piping material and PVC piping systems are:

  • Corrosion-resistant
  • Cost-effective
  • Widely accepted by codes
  • Easy to install
  • Easy to handle
  • Environmentally sound
  • Provide long service life

Descriptions and applications of PVC joints

The following is a list of some commonly used PVC joints available. Each entry contains a description of PVC joints as well as applications for it.


PVC tees are fitting with three ends; two in a straight line and one on the sideline at an angle of 90 degrees. Tees can be used to connect two lines into one mainline and it is also called PVC structures. Most of the tees have split socket ends but there are threaded versions also available.


The plug is a basic component of the plumbing component and it is generally used to close the opening of the pipe during repairs and inspections. Plugs are similar to caps, but the only difference is they do not stop the flow in a pipe. Plugs have a male-threaded end.


Caps are used to stop the flow of the pipe and it can add a finished look to pipe in building projects. Caps are available in different materials like steel, plastic, copper, rubber, etc.


Coupling is used to connect the pipes of the same diameter and it is very useful if the pipe is damaged, broken or leakage occurs. There are two types of coupling are available namely slip coupling and compression coupling. Coupling is a small part of the pipe and it is used to connect or couple one part of the pipe to another part. They can connect pipe to pipe or fitting to fitting.


The union is a type of pipe joint and the function is similar to coupling. But coupling cannot be removed after fixing. The union consists of both male and female ended threads and nuts. It is very useful for maintaining the pipe.

Hot and cold water piping system in CPVC

CPVC is an abbreviation that stands for Chlorinated Poly Vinyl Chloride and CPVC pipe manufacturers using the best Japanese technology to manufacture Cpvc pipes. CPVC pipe is produced by chlorination of conventional polyvinyl chloride (PVC) and also, it gives more strength. It can withstand very high temperatures when compared to the PVC piping system.

Temperatures over this CPVC pipe can cause weakening of joints and soften of material. CPVC pipes can be used for various applications like water supply, industrial process lines, fire fighting systems, swimming pools, irrigation, agriculture, etc. some of the advantages in CPVC pipe include high flow rates, lightweight, long life, economical, chemical resistance, excellent corrosion, easy and fast installation, easy to handle, etc. CPVC pipe manufacturers are manufacturing a good quality CPVC pipe for longer life.

The bottom line

CPVC has many tremendous advantages over other pipes as well. CPVC pipe is generally a stable compound and it will not corrode as easily as other pipes. It can withstand for long service life.
