Brass nipple coupling for plumbing systems

The Legend Valve 311-225 is a 4" x 3-1/2" no-lead red brass nipple designed for joining pipe sections in residential and commercial plumbing installations. It suits contractors and maintenance crews who need a reliable, corrosion-resistant connector for water supply lines.

No-lead red brass construction with tapered threads

The no-lead red brass alloy meets modern health and safety standards while providing durable resistance to dezincification and seasonal temperature changes. Tapered pipe threads create a tight seal when assembled with compatible fittings, reducing the risk of leaks during pressure testing and daily operation.

Replaces worn or non-compliant nipples in existing

This coupling upgrades older brass or galvanised nipples that may contain lead or show signs of corrosion, scaling or thread damage. The jump is worth it when bringing a system into compliance with current no-lead requirements or when restoring joint integrity without replacing the entire pipe run.
