  • No-lead alloy meets strict drinking-water standards

2" x 5" No Lead Red Brass Nipple

This no lead red brass nipple connects two female threaded components in plumbing systems. It is intended for installers who need a straight, corrosion resistant connector for water supply lines. The fitting meets no lead requirements for potable water applications.

Replacing damaged or corroded nipples

Use this nipple to replace a section of threaded pipe that has leaked, corroded or been damaged during service. The jump is worth it when the existing threads are stripped or the pipe wall has thinned enough to risk failure under pressure.

Installation notes

Thread the nipple into female fittings using pipe thread sealant or tape approved for potable water. Over tightening can crack the brass or split the female fitting, so stop when the joint feels snug and does not leak under test pressure.

Questions about this item

What thread size does the 2-inch red brass nipple require for connection?

The 2-inch nominal pipe size uses standard NPT threads; mate it with 2-inch NPT fittings and apply thread sealant rated for potable water.

How do I install the 5-inch nipple without damaging the no-lead brass threads?

Hand-tighten the nipple into each fitting, then finish with a strap wrench for one to two turns; avoid pipe wrenches that can gouge the softer red brass.

When should the 311-168 nipple be inspected or replaced in a potable-water system?

Inspect annually for green patina, weeping joints or dezincification; replace immediately if threads show galling or the body develops pinhole leaks.
