Product identity

The Legend Valve 355-220E is a 4-inch close Schedule 40 black nipple used to join two female-threaded pipe ends in plumbing systems. It suits installers who need a short, rigid connector for water, gas or oil lines where a standard coupling would be too long.

Sustained service behaviour

Schedule 40 wall thickness gives the fitting the pressure rating required for continuous service in residential and light-commercial piping. The black steel construction handles normal operating temperatures and mechanical vibration without the deformation that can occur with thinner-walled alternatives under constant load.

Deciding specification

The close length means the nipple has barely more thread engagement than the two ends themselves, so it only fits installations where the mating faces are almost touching. Buyers who need a measurable gap between components must choose a longer nipple instead.

Questions about this item

How much heat does the 4-inch Schedule 40 nipple generate during continuous flow?

The black steel nipple is a passive fitting; it produces no heat of its own and simply conducts the temperature of the fluid passing through it.

Which threads or tools must I already have to install this 355-220E nipple?

You need matching 4-inch NPT threads on the adjoining pipe or fitting and a pipe wrench large enough for 4-inch iron pipe.

Will this Schedule 40 black nipple mate with older galvanized or brass fittings I already own?

Yes — the standard NPT threads on the 355-220E engage with legacy galvanized, black-iron or brass fittings of the same nominal size.
