CPVC Coupler (also known as CPVC Socket) :
Couplers are fittings that connect two pipes together in order to extend the pipeline in one direction. CPVC Couplers are of two types plain couplers and threaded couplers which are sometimes also known as adaptors.
CPVC is chlorinated polyvinyl chloride plastic which is a high quality, strong plastic that withstands temperature upto 93 Deg C
CPVC Coupler or Socket (Plain):
Plain Couplers have pipe joint on both sides using CPVC solvent cement. Sockets are also available in reducing type called CPVC Reducing Sockets or Couplers which connect a pipe of higher size with one of smaller size.
CPVC Brass Threaded Adaptor:
Brass threaded adaptors have brass threaded inserts on one end and CPVC on the other so as to connect the pipe to the bathroom fittings or other plumbing fixtures.
Brass threaded adaptors can be male threaded or female threaded.
CPVC Threaded Adaptor (plastic):
Plastic threaded adaptors available in both male and female threaded types have inner threads of CPVC as well as such one must be careful while tightening them with metallic plumbing fixtures. These kind of adaptors are not recommended for use with Hot water.
Our products are best suited for both homemakers and contractors or builders as they are affordable without compromising with the quality.

FAQs
A CPVC coupling is a fitting used to join two CPVC pipes of the same diameter in a straight line. It is commonly used in residential, commercial, and industrial hot- and cold-water plumbing systems.
Choose a coupling that matches the nominal size and compatible CPVC pipe system being installed. Checking the pipe and fitting specifications before installation helps ensure a proper joint and reduces the risk of leakage.
Yes. CPVC couplings are designed for CPVC plumbing systems that carry both hot and cold water. However, the coupling should always be selected according to the manufacturer’s rated temperature and pressure limits.
For a reliable joint, ensure the pipe ends are clean, properly cut, and correctly fitted before applying the manufacturer-recommended CPVC solvent cement. Proper insertion and curing time are also important for joint strength.
Plumbers should check pipe compatibility, fitting size, joint alignment, solvent-cement suitability, and the system’s operating temperature and pressure. Following the manufacturer’s installation instructions helps achieve a durable, leak-resistant connection.
