PVC fittings connect, redirect and terminate pipe runs, and getting the right one for the job makes an installation faster, neater and less prone to leaks. Here is a plain-English guide to the fitting types you will come across in our range.
Bends
Bends change the direction of a pipe run. They are usually specified by angle (for example 11.25°, 22.5°, 45° or 90°) and by radius -- a long-radius bend curves more gradually than a short-radius ("lobster") bend of the same angle. Long-radius bends reduce flow turbulence and pressure loss, which matters more on pressure lines; short-radius bends are more compact and useful in tight spaces such as drainage runs.
Tees and junctions
A tee (or junction) splits a single pipe run into two directions. An equal tee has outlets the same diameter as the main pipe, while a reducing junction steps down to a smaller diameter branch -- handy when a smaller feeder line comes off a larger mainline. Reducing junctions are described by both diameters, for example "95° 110mm" reducing to a smaller branch size.
Equal crosses
An equal cross splits a pipe run in four directions at once from a single fitting, which can simplify a layout compared to using two separate tees, provided your design calls for a true four-way split.
Adaptors and sockets
Adaptors and sockets join pipe to pipe, or pipe to a fitting with a different thread or material (for example a CL16 to AC/CL16-to-BSP male/female adaptor). Double sockets and repair couplings are especially useful for repairing a damaged pipe section without having to re-route the whole run.
Rodding eyes
A rodding eye provides a removable access point for clearing blockages or inspecting a drainage line, and is normally fitted at points in a stormwater or sewer run where maintenance access is likely to be needed.
Putting it together
Most installations use a combination of these fittings: bends to route around obstacles, tees or junctions to branch off a supply, and adaptors to transition between pipe classes or materials.
