Brass Nipple for Plumbing Systems

The Legend Valve 311-149 is a no-lead red brass nipple sized 1-1/2" x 5-1/2". It connects two female-threaded fittings in water supply or heating installations. The brass construction resists corrosion in potable and hydronic systems. Installers use it where a fixed-length spacer is required between components.

Sustained Pressure and Temperature Performance

Red brass handles continuous water pressure and elevated temperatures found in recirculating loops. The alloy resists dezincification better than yellow brass when exposed to aggressive water chemistry. Thread engagement remains tight through thermal cycling without the need for frequent retightening. The material meets no-lead requirements for drinking water safety.

Build Quality and Thread Compatibility

The nipple features NPT threads cut to standard taper for a reliable seal with pipe dope or tape. Red brass provides sufficient wall thickness to withstand mechanical stress during assembly. California Proposition 65 warnings apply due to trace elements in the alloy. The fitting suits new installations or repairs in residential and commercial plumbing.

Questions about this item

Does the 311-149 brass nipple generate noise, heat or draw power when installed in a plumbing system?

The 311-149 brass nipple is a passive fitting with no moving parts, so it produces no noise, no heat and consumes no power during continuous use.

What pipe thread size must the existing piping have to connect the 311-149 nipple without adapters?

The nipple has 1-1/2 inch male pipe threads on both ends, so the mating pipes or fittings need matching 1-1/2 inch female threads.

Will the 311-149 no-lead red brass nipple cause galvanic corrosion when joined to older copper or galvanised steel pipe?

Red brass is compatible with copper and generally resists galvanic action better than yellow brass; dielectric unions are recommended when connecting directly to galvanised steel.
