Zoro Select 5P452 Reducing Elbow

The Zoro Select 5P452 is a 90-degree reducing elbow made from malleable iron for piping systems. It connects a 1-1/2 inch female NPT thread to a 1 inch female NPT thread. The fitting carries a Class 150 pressure rating for standard plumbing and industrial use. It suits installers who need a durable direction change with a size reduction.

Replaces Straight Reducers And Separate Elbows

This single fitting replaces a combination of a straight reducer and a separate 90-degree elbow in a pipeline. The jump is worth it when space is limited or when fewer joints are preferred to reduce potential leak paths. It simplifies assembly by combining the direction change and size transition into one component. Installation is faster with only two threaded connections to seal.

Fits Threaded Iron Or Steel Pipe Networks

The elbow threads directly onto male NPT pipe ends with 11-1/2 threads per inch. It needs compatible male-threaded pipe nipples or fittings on both sides to complete the connection. The malleable iron body handles typical water, air and gas lines within its Class 150 rating. It frees up space by eliminating the extra fitting length a two-piece assembly would require.

Questions about this item

What size NPT threads does the 1-1/2 inch inlet and 1 inch outlet use?

Both ends are Female NPT with 11 1/2 threads per inch, matching the Class 150 malleable iron specification.

How should the elbow be sealed during installation, and what is the common mistake?

Apply PTFE tape or pipe dope to the male threads before threading into the female NPT ports; the frequent error is over-tightening, which can crack the malleable iron casting.

When should the reducing elbow be inspected or replaced in a plumbing system?

Check for corrosion, leaks or thread damage during routine system maintenance; replace if the Class 150 pressure rating is exceeded or the iron shows visible degradation.
