Pipe Fittings

Select material based on the pipe system's media, pressure, temperature, and corrosion resistance needs: PVC/CPVC for low‑temperature water and chemicals, copper or brass for potable water and heat, stainless steel for corrosive or high‑temperature applications, and carbon steel for high‑pressure industrial lines

Match fittings to the pipe nominal size and connection type used in your system — common types include threaded (NPT/BSP), solder/c sweat, compression, push‑to‑connect, flanged, and welded ends; confirm inner/outer diameters and thread standards to ensure compatibility

Push‑to‑connect fittings offer quick installation and are reliable for many domestic and light commercial systems, but for high‑temperature, high‑pressure, or buried applications, consider mechanical, soldered, welded, or flanged connections specified for those conditions

Choose fittings with pressure and temperature ratings that meet or exceed the maximums of your system; ratings vary by material and design — check manufacturer specifications for maximum allowable working pressure (MAWP) and temperature range rather than assuming based on appearance

Ensure proper pipe end preparation (clean, deburred, correct length), use the correct sealing method for the connection type (thread sealant or tape for threaded, soldering technique for sweat joints, correct gasket type and torque for flanges), and follow recommended installation torque and procedures

Periodically inspect fittings for signs of corrosion, leakage, loosening, or physical damage; check seals and gaskets for degradation and verify torque on mechanical connections according to maintenance schedules or after pressure cycling

Individual fittings can range from a few dollars for simple plastic or small brass pieces to tens or hundreds of dollars for large, specialty, or high‑grade metal fittings; average product prices in this category tend to cluster around mid‑range options
