When selecting plumbing fittings, several factors need to be considered, such as the type of plumbing material, intended application, pressure requirements, and local plumbing codes. Here are some commonly used and reliable plumbing fittings:
1. Compression fittings: Compression fittings are suitable for connecting copper pipes, PEX pipes and CPVC pipes. They consist of a compression nut, a compression ring (also known as an "olive"), and a fitting body. These fittings create a tight seal by pressing the ring against the pipe when the nut is tightened.
2. Threaded pipe fittings: Threaded pipe fittings are available in brass, stainless steel, PVC and other materials for connecting galvanized steel, brass or iron pipes. These fittings have male and female threads that screw together to create a watertight joint. Common threaded fittings include elbows, tees, couplings and adapters.
3. Push-on fittings: Push-on fittings are also called quick connect or push-in fittings, which are easy to install and do not require special tools. They are commonly used on PEX and copper pipe. These fittings feature a collet mechanism that grips the pipe as it is inserted, providing a secure and leak-free connection.
4. Solvent welded fittings: Solvent welded fittings are used to join PVC and CPVC pipes. These fittings require the use of solvent adhesives that chemically fuse the pipe and fitting together to form a strong joint. Common solvent welded joints include elbows, tees, unions and reducers.
5. Flare Fittings: Flare fittings are commonly used to join copper, brass or stainless steel pipe. They consist of flare nuts, flare fittings and pipe flare ends. The flared end of the pipe presses against the tapered fitting, creating a tight seal when the nut is tightened.
6. SharkBite Fittings: SharkBite fittings are push-fit fittings for PEX, copper, CPVC, and PVC pipe. These fittings feature stainless steel clamping rings and O-ring seals to provide a reliable connection without tools or welding.
