2-inch Black Merchant Coupling

The Legend Valve 350-708 is a 2-inch black merchant coupling designed for joining two sections of pipe in plumbing systems. It suits professional installers and maintenance crews who need a standard NPSC threaded connection for water or gas distribution.

NPSC Thread Limits

The coupling uses NPSC straight threads which seal on the thread flanks rather than a taper, so a compatible sealant or tape is required to prevent leaks. It is not intended for high-pressure hydraulic lines or applications that demand a tapered NPT seal.

California Proposition 65 Notice

This product contains a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. Verify that local codes permit the material and that your existing pipe threads match the NPSC standard before ordering.
