Product identity

Legend Valve 355-216E is a 3" x 12" Schedule 40 black nipple designed for plumbing drain and trap installations. The component carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm. Professional installers and maintenance teams select it for standard waste-line connections.

Pre-installation checks

Verify that the existing piping uses a matching 3-inch nominal size and Schedule 40 wall thickness before ordering. Confirm local code acceptance of black steel nipples for the intended drain or trap application. Ensure the 12-inch length suits the available space between fittings without requiring field modification.

Build and daily use

The black steel construction provides mechanical strength for typical residential and commercial drainage runs. Threaded ends allow direct engagement with compatible fittings using standard pipe-thread sealant or tape. The opaque finish hides surface discoloration that can appear on lighter materials over time. The Proposition 65 notice means installers should follow safe-handling practices such as wearing gloves and washing hands after assembly.

Questions about this item

Does the 3" x 12" Schedule 40 black nipple arrive ready to install or do I need extra fittings?

The nipple is a single threaded pipe section; any couplings, elbows or sealant required for your specific drain layout must be purchased separately.

How do I decide between the 355-216E and other Legend Valve nipple sizes?

Match the 3-inch nominal diameter and 12-inch length to your existing piping; the 355-216E model number identifies this exact combination.

What does the Schedule 40 rating tell me about pressure handling in a real plumbing system?

Schedule 40 indicates a standard wall thickness for 3-inch steel pipe, suitable for typical residential and light-commercial drainage pressure loads.
