Legend Valve 355-210E Schedule 40 Nipple

This Legend Valve 355-210E nipple is a Schedule 40 black steel fitting designed for joining pipe sections in plumbing systems. It suits installers who need a standard 3-inch by 6-inch connection for water, gas or oil lines. It is not for buyers who require a different diameter, length or material such as galvanised or stainless steel.

Sustained pressure performance

The Schedule 40 wall thickness provides the strength needed for continuous pressure service in residential and commercial piping. The black steel construction handles sustained loads without deformation when installed within its rated pressure class. It is not for systems that exceed the pressure rating for Schedule 40 fittings at the operating temperature.

Installation and common issues

The tapered NPT threads allow a tight seal when assembled with appropriate thread sealant or tape. Over-tightening can crack the fitting or strip the threads, while insufficient sealant leads to leaks. The product carries a California Proposition 65 warning for chemicals known to cause cancer and birth defects or other reproductive harm.

Questions about this item

Does the 355-210E nipple generate any noise, heat or draw power when installed in a pressurised system?

The 355-210E is a passive Schedule 40 black steel nipple with no moving parts, electrical connections or internal flow restrictions, so it produces zero noise, zero heat and consumes no power during continuous operation.

What pipe threads or fittings must I already have to connect this 3-inch by 6-inch nipple?

You need matching 3-inch NPT threaded pipe, couplings or valves on both ends; the nipple itself is a plain Schedule 40 black steel tube with male threads cut to the 355-210E specification.

Will the 355-210E nipple mate reliably with older black iron pipe already in my building?

Yes, the nipple follows standard Schedule 40 dimensions and NPT threading, so it threads directly into existing 3-inch black iron pipe and fittings of the same schedule without adapters.
