Legend Valve 311-131 Brass Nipple
This Legend Valve 311-131 brass nipple provides a 1-1/4 inch by 7 inch connection for fluid distribution systems. It is intended for installers and maintenance crews working on grounds maintenance or outdoor equipment manifolds. The no-lead red brass construction meets material requirements for potable water applications. This component suits new installations or replacements in compatible piping networks.
Sustained pressure and corrosion resistance
The brass alloy resists dezincification and scale buildup during continuous exposure to treated or untreated water. Thread integrity remains stable under normal operating pressures found in irrigation and hydronic loops. The material withstands seasonal temperature cycling without cracking or galling. Long-term reliability depends on correct thread sealant and proper torque during assembly.
Threaded pipe interface limits
The 1-1/4 inch NPT threads dictate the maximum pipe size and pressure class this nipple can join. Brass threads can strip if overtightened or mated with mismatched steel fittings. Thermal expansion differences between brass and dissimilar metals may loosen joints over time. California Proposition 65 warnings indicate the presence of chemicals known to cause cancer and reproductive harm.

Questions about this item
Does the brass nipple generate heat or noise during continuous water-flow use?
The 1-1/4" x 7" brass nipple is a passive fitting with no moving parts, so it produces no operational noise and adds negligible heat to the fluid stream.
What pipe threading must already be present on my system for the 311-131 nipple to install correctly?
Both ends require standard 1-1/4" NPT male threads; the connecting pipes or manifolds must provide matching female NPT ports.
Will the no-lead red brass alloy of the 311-131 nipple corrode when joined to older copper or galvanised-steel piping?
The no-lead red brass resists dezincification and is compatible with copper; use a dielectric union when transitioning to galvanised steel to prevent galvanic corrosion.
