Coupling fittings are used to join two or more pipes in a straight line thus enhancing a continuous pipe run.
Moreover, they are also applied to allow for easier replacement of
pipes or broken fittings.
Specifications
We have PVC couplings at different sizes.
Couplings are available in various types.
Their uses depend on the type, material, pressure ratings and sizes.
Choosing the Appropriate Couplings
Appropriate couplings for irrigation systems will depend on the pipe material, size and specific requirements of the plumbing system.
Types of Coupling Fittings
Common Couplings
Compression Coupling – Consists of two compression nuts, compression rings (ferrules) and a compression seat.
Slip Couplings
They have a sliding mechanism that allows them to be adjusted in length.
Push-to-connect coupling
For a quick and tool free installation of pipes.
They are suitable for
modern irrigation and plumbing systems.
Threaded Couplings
With female threads on both ends to connect male threaded pipe ends. They are normally best for plumbing systems and irrigation pipes.
How to Install Coupling Fittings
Compression Coupling
To install a compression coupling, insert the pipes into each end of the coupling until they reach the compression seat. Tighten the nuts onto the coupling then compress the rings against the pipes to create a secure connection.
Slip Coupling
When installing a slip coupling, first cut the damaged or faulty part of the pipe. Insert the slip coupling onto one end of the pipe. Insert the other end of the pipe into the opposite end of the slip coupling. Slide the slip coupling to cover the damaged section.
Push-to-connect coupling
The design helps in connecting pipes by pushing them into the fitting until they reach the internal stop. The fittings built in rings provide a tight and secure connection.
Threaded Couplings
Typically, installation of threaded couplings is easier. Apply a thread seal on the male threads of pipes and screw the coupling onto the pipe. This process enhances formation of a secure seal that guarantees lower chances of leakage.
