Zoro Select 5P556 Coupling for 1-1/2" Pipe

This Zoro Select coupling joins two sections of 1-1/2 inch pipe in plumbing systems. It suits installers who need a straight, female-threaded connection made from malleable iron. The Class 150 rating indicates its pressure class for standard applications.

Installation uses standard FNPT threading on both

Thread each pipe end into the coupling by hand before tightening with a pipe wrench. Apply appropriate thread sealant to prevent leaks at the joint. The most common issue is cross-threading during initial engagement, which damages the 11 1/2 threads per inch pattern.

Class 150 pressure rating defines the operating

This single specification determines whether the fitting matches the system pressure requirements. It is not for installations exceeding the Class 150 designation or for pipes with a different nominal diameter. Buyers needing a higher pressure class or a different pipe size must select an alternative fitting.

Questions about this item

How do I confirm the coupling is sealing properly after threading it onto 1-1/2" pipe?

Apply pressure up to the Class 150 rating and check for leaks at the FNPT threads; a dry, tight joint with no weeping indicates correct installation.

What comes in the box and do I need any extra parts to install it?

The box contains the malleable iron coupling only; you must supply pipe thread sealant or tape and the mating 1-1/2" FNPT pipe sections separately.

Which version should I choose for a standard 1-1/2" Class 150 piping system?

Select the 5P556 model — it is the straight malleable iron coupling rated Class 150 with 1-1/2" FNPT threads on both ends.
