Zoro Select 45° Elbow 3/8" FNPT

The Zoro Select 45 Degree Elbow is a malleable iron pipe fitting rated to Class 300. It features a 3/8 inch female National Pipe Taper thread on each end to join two male-threaded components at a 45-degree angle.

Suits 3/8" FNPT piping systems

This fitting suits installers joining two male NPT threads at a 45-degree offset in a Class 300 malleable iron system. It does not suit systems requiring a different thread standard or a different nominal bore size.

Class 300 pressure rating

The single specification that decides fitment is the Class 300 pressure rating combined with the 3/8 inch FNPT thread type. Verify that your piping schedule and pressure requirements match this class before installation.

Questions about this item

How do I install the 3/8" FNPT threads without cross-threading the malleable iron?

Clean both male and female threads, apply PTFE tape clockwise on the male end, hand-tighten until resistance, then finish with a wrench — stop when the joint feels solid to avoid cracking the Class 300 fitting.

What maintenance or replacement will this elbow need over time?

Inspect the malleable iron body and FNPT threads annually for corrosion, mineral buildup or thread deformation; replace the fitting if leaks appear or the 45-degree angle shows stress cracks from vibration.

What pressure limit appears first during sustained use at the Class 300 rating?

The 300 psi working-pressure ceiling of the malleable iron body is the first limit; sustained pressure near that value can accelerate thread wear or cause micro-fractures before any other component fails.
