Zoro Select 5P451 Reducing Elbow

The Zoro Select 5P451 is a 90-degree reducing elbow constructed from malleable iron for Class 150 service. It connects a 1-1/2 inch female NPT thread to a 1-1/4 inch female NPT thread, both with 11-1/2 threads per inch. This new fitting redirects flow in piping systems while transitioning between two pipe sizes.

Suited for plumbing and industrial pipe

Installers who need to change direction and reduce pipe diameter in a single joint will use this elbow. It is not intended for systems that require a straight coupling or an equal-sized 90-degree bend. Buyers needing different thread standards, pressure classes, or material grades should select an alternative fitting.

Fits into NPT-threaded piping assemblies

The elbow threads directly onto male NPT pipes or nipples of the matching sizes and thread count. No welding, soldering, or special tools are required beyond standard pipe wrenches and sealant. Its malleable iron body handles the mechanical loads of the joint, freeing the installer from adding separate reducers and elbows.

Questions about this item

What pipe threads do I need on my existing lines to connect this 90 degree reducing elbow?

Both ends use Female NPT threads with 11 1/2 threads per inch, sized for 1-1/2 inch and 1-1/4 inch nominal pipe.

Will this Class 150 malleable iron elbow handle the same pressure as the older galvanised fittings I am keeping in the system?

Class 150 malleable iron is rated for standard water, oil and gas service at moderate pressures typical of residential and light commercial plumbing.

How can I confirm the elbow is seated correctly after I tighten it onto the pipes?

The joint should show full thread engagement with no visible gaps, and a pressure test at working pressure should hold without leaks.
