4" x 11" Schedule 40 Black Nipple

The Legend Valve 355-235E is a 4" x 11" Schedule 40 black steel nipple designed for connecting female-threaded pipe fittings in plumbing systems. It provides a durable, rigid link for water, gas or oil lines where a straight, threaded section is required. The pipe nipple is supplied new and ready for installation in residential or commercial pipework.

Replaces worn or damaged threaded pipe sections

This nipple replaces a corroded, cracked or incorrectly sized section of 4" Schedule 40 black pipe without the need for cutting and threading on site. The jump is worth it when the existing pipe run has a standard 11" centre-to-centre spacing and the installer wants a factory-threaded, consistent wall-thickness piece that meets Schedule 40 pressure ratings.

Suits plumbers and maintenance teams needing

It suits installers who need a ready-made 11" length of 4" Schedule 40 black pipe for a direct repair or new assembly. Buyers who require a different length, a galvanised finish or a fitting with a different schedule rating should look at alternative pipe nipples or fittings.

Questions about this item

What thread size and length does the 4" x 11" Schedule 40 black nipple need to fit?

The nipple has a 4-inch nominal pipe size and an 11-inch overall length with Schedule 40 wall thickness, requiring matching 4-inch NPT female threads on both ends for a proper fit.

How do I install the 355-235E black nipple without damaging the threads?

Apply PTFE tape or pipe dope to the male threads, hand-tighten into the female fitting, then use a pipe wrench on the nipple body to turn it one to two full turns past hand-tight without over-torquing.

When should I replace the Schedule 40 black nipple due to corrosion or wear?

Replace the nipple if you see heavy rust scaling, thread deformation, or leaks at the joints, especially in systems exposed to moisture or chemicals referenced under Proposition 65 warnings.
