45 Degree Street Elbow 1-1/4

The Zoro Select 45 degree street elbow connects a 1-1/4 inch female threaded pipe to a 1-1/4 inch male threaded pipe. It is made from malleable iron rated for Class 150 service. This fitting suits plumbing systems that require a 45 degree directional change.

Class 150 Schedule 40 Rating

The Class 150 designation and Schedule 40 wall thickness define the pressure boundary for this elbow. It handles a maximum operating pressure of 300 psi at 150 degrees Fahrenheit. These ratings determine whether the fitting matches the design pressure and temperature of the piping system.

Threaded Malleable Iron Installation

The male and female NPT threads allow direct assembly onto matching pipe ends without welding or flanges. Malleable iron requires appropriate thread sealant or tape to prevent leaks at the joints. Over-tightening can crack the casting, so installers should follow standard practice for iron fittings.

Questions about this item

Will the malleable iron threads need re-taping or replacement after repeated assembly?

The malleable iron threads are designed for standard NPT engagement; re-apply PTFE tape or pipe dope each time the joint is broken and re-made to maintain the 300 psi seal.

What pressure limit governs continuous operation at the rated temperature?

The fitting is rated for 300 psi maximum operating pressure at 150 °F; sustained service above either value exceeds the Class 150 design envelope.

Does the iron body radiate noticeable heat when the line runs at 150 °F all day?

At 150 °F the elbow will become hot to the touch and transfer heat to surrounding air; insulate the pipe run if personnel contact or heat loss is a concern.
