Valve fitting for fluid systems

The Legend Valve 311-206 is a 3" x 4" no-lead red brass nipple designed for connecting pipe sections in plumbing and irrigation networks. It serves installers and maintenance crews who need a compliant component for potable water or outdoor fluid distribution.

Threaded connection for pipe assemblies

This nipple joins two female-threaded fittings or valves, allowing a straight run between components of differing nominal sizes. Its brass construction resists corrosion in buried or exposed installations and satisfies no-lead requirements for drinking-water systems.

Proposition 65 compliance notice included

The product carries California Proposition 65 warnings for chemicals linked to cancer and reproductive harm. No additional accessories, sealants or software are bundled; the fitting is supplied as a single brass component ready for thread sealing on site.

Questions about this item

What is the first limit reached during sustained use of this brass nipple?

The nipple is a passive fitting with no moving parts or power draw, so it does not reach a thermal or mechanical limit under normal sustained flow.

How much noise, heat or power does this fitting generate when installed all day?

It produces no noise, no measurable heat and consumes no power because it is a solid brass connector with no active components.

What existing piping must I already have for this 3 inch by 4 inch nipple to work?

You need male NPT threads on both sides — one 3 inch and one 4 inch — so the nipple can thread directly into each fitting.
