Find the Right Water Fitting
Pick your pipe size, then your fitting standard, and we'll show you exactly which fittings work with your setup — couplings, elbows, tees, adapters, end caps, and shut-off valves.
1. Pipe size
2. Connection standard
3. Your fittings
Step 1 — What size is your pipe?
Measured across the outside of the pipe. Not sure? Wrap a string around the pipe, measure the length, divide by 3.14 (that's your outer diameter).
