Plumbers needing a galvanized Class 150 cap

This cap suits installers closing a 1 1/4 inch female NPT connection in a Class 150 malleable iron system. Buyers who need a different nominal pipe size, a higher pressure class, or a fitting that ships with thread sealant already applied should look at other options.

Class 150 pressure rating

The single specification that determines whether this is the correct part is the Class 150 pressure rating. Verify that your piping system operates within this class before installation.

Questions about this item

What thread size does the 1 1/4 in cap use?

The cap uses a Female NPT thread that matches a 1 1/4 in nominal pipe size.

How do I install the malleable iron cap and what step is often missed?

Wrap the male threads with PTFE tape or pipe dope, then tighten the cap by hand plus one to two turns with a wrench; the step often missed is applying sealant before threading.

When should the galvanised Class 150 cap be replaced?

Replace the cap if the galvanised coating shows white rust, red rust, or if the threads become damaged and no longer seal.
