Legend Valve 311-216 3 inch by 12 inch brass nipple

Brass Nipple for Plumbing Systems

The Legend Valve 311-216 is a 3 inch by 12 inch brass nipple designed for joining two female-threaded pipe ends in water or gas distribution. It suits professional plumbers and maintenance crews who need a straight, rigid connector in a no-lead red brass alloy. The component meets California Proposition 65 disclosure requirements for listed chemicals. Buyers who need a flared, compression or push-fit connection cannot use this threaded nipple.

Behaviour Under Continuous Pressure

The red brass construction resists dezincification and corrosion when subjected to constant fluid pressure and variable temperatures in supply lines. Its solid bar-stock body maintains dimensional stability without the creep seen in softer alloys during long-term service. The uniform thread profile ensures consistent engagement across the full 12 inch length. Installers who require a flexible or vibration-absorbing link should select a different fitting type.

Thermal and Environmental Performance

Brass conducts heat rapidly, so the nipple reaches fluid temperature quickly and dissipates thermal stress evenly across its walls. No moving parts or seals exist to generate noise, leak paths or wear under normal flow conditions. The no-lead alloy satisfies potable-water safety standards while retaining the mechanical strength of traditional red brass. Systems requiring electrical isolation between pipe sections must add a dielectric union separately.
