4-Inch 45-Degree Street Elbow

This Legend Valve 350-071 fitting connects a female NPT thread to a male NPT thread at a 45-degree angle. The 4-inch black steel construction suits industrial plumbing and hydraulic systems. It is a new component supplied for permanent installation.

For Plumbers Needing a 45° Male-to-Female Joint

Installers who require a street elbow with FNPT and MNPT ends in a 4-inch nominal size will find this part matches that specification. Projects demanding a different angle, alternative thread types, or other material grades cannot use this fitting.

45-Degree FNPT x MNPT Configuration

The defining specification is the 45-degree street elbow geometry combining a female NPT inlet with a male NPT outlet. This exact thread orientation determines whether the coupling fits the intended piping layout.

Questions about this item

What pipe size fits the 4" black 45° street elbow?

The fitting is made for four-inch nominal pipe and connects female NPT threads to male NPT threads.

How do I install the 45° street elbow without cross-threading the FNPT x MNPT joint?

Clean both threads, apply pipe sealant, hand-tighten until snug, then finish with one to two full turns using a wrench on the hex flats.

When should I replace the 4" black 45° street elbow in a plumbing system?

Inspect for corrosion, cracks or thread damage at each service interval; replace immediately if leaks appear or the fitting shows visible wear.
