Brass Clamp-Style Fittings, 3/4 Inch — 12 Piece Kit, 3/4 NPT Female Thread
Twelve clamp-style brass adapters in 3/4 inch with 3/4 inch NPT female threads, and twelve stainless steel clamps.
3/4 inch is your main line — the trunk coming off the meter or the heater before it splits down to 1/2 inch for the fixtures. This is how you get that run onto pipe thread.
Solid lead-free brass. Works with PEX and PP pipe. Crimp tool for the clamps.
Rated to 100 PSI and 180 degrees Fahrenheit. Hot and cold water lines, hydronic heat, water heater and pressure tank hookups.
Water only. These are not for gas.
Twelve is about right for a house — you don't need many threaded transitions, but the ones you need, you really need.
