Legend Valve 355-205E Schedule 40 Nipple

This Legend Valve 355-205E nipple is a Schedule 40 plumbing component sized at 3" x 3-1/2" with a black finish. It connects drain or trap sections in residential and commercial waste systems. The transparent colour coding helps identify the fitting during assembly. Installers handling DWV piping will find it matches standard iron pipe dimensions.

Replaces damaged or corroded trap nipples

The fitting replaces a worn nipple on an existing trap or drain assembly without changing the surrounding pipework. A swap is worth it when threads are stripped, the wall is cracked or mineral build-up restricts flow. The Schedule 40 wall thickness matches the original specification so the joint retains its pressure rating. No adapter is required for like-for-like replacement.

Withstands continuous drainage flow

Under sustained load the nipple maintains its shape because the Schedule 40 wall resists deformation from hot water and chemical exposure. The black coating protects the steel from surface corrosion during long service periods. Threads stay sealed when the system cycles repeatedly between full flow and static head. California Proposition 65 warnings apply to the materials used.

Questions about this item

What size and schedule pipe does the 355-205E nipple connect to?

The nipple is a 3" x 3-1/2" Schedule 40 black nipple, so it threads into matching Schedule 40 fittings of the same nominal size.

How do I install the nipple without damaging the threads?

Apply PTFE tape or pipe dope to the male threads, hand-tighten, then finish with a wrench no more than one to two turns past hand-tight.

When should I replace this trap nipple?

Replace it if you see corrosion, cracking, or leaks at the threads, or during any drain rework that disturbs the joint.
