Plumbing Nipple for Drain Connections

This Legend Valve 355-206E nipple connects 3 inch and 4 inch Schedule 40 piping in drain and trap assemblies. The black finish identifies the fitting for standard drainage use. It is supplied new and ships directly from the manufacturer.

Installers Working With Mixed Pipe Diameters

The fitting suits plumbers joining dissimilar pipe sizes in waste lines. It does not serve systems requiring uniform diameters or press-fit connections. Buyers needing copper, PVC or stainless transitions should select alternative fittings.

Performance Under Continuous Flow

The Schedule 40 wall thickness handles sustained drainage loads without deformation. The material resists corrosion from typical waste water exposure. California Proposition 65 warnings apply for chemical content.

Questions about this item

What size pipe threads does the 355-206E nipple require for a watertight seal?

The nipple has 3-inch and 4-inch Schedule 40 tapered threads, so the mating fittings must match those exact dimensions.

Will this black steel nipple corrode faster when connected to existing galvanised pipework?

Direct contact between black steel and galvanised steel can accelerate corrosion; use a dielectric union or brass transition fitting to separate the metals.

How can I confirm the 355-206E is seated correctly after assembly?

Pressurise the system and check every joint for leaks; a properly threaded Schedule 40 connection shows no seepage at the rated working pressure.
