Malleable Iron Cap 1/2 in Threaded

This malleable iron cap provides a 1/2 inch threaded closure for piping systems. It is rated Class 150 and uses female NPT threads. The galvanized finish adds corrosion resistance for plumbing installations. No pre-applied thread sealant or seal is included with the cap.

Galvanized Class 150 Fitting

The galvanized malleable iron construction handles standard plumbing pressures at Class 150 rating. Threaded female NPT connection installs with standard pipe tools. California Proposition 65 warnings apply for cancer and reproductive harm risks. The fitting contains no pre-applied sealant requiring separate thread preparation.

Threaded Pipe End Closure

This cap seals the end of a 1/2 inch nominal pipe size line under sustained system pressure. Malleable iron material maintains structural integrity during continuous service conditions. Galvanized coating resists degradation from prolonged fluid exposure. Separate thread sealant must be applied during installation for leak-free performance.

Questions about this item

How do I install the 1/2 in female NPT cap without leaks?

Wrap PTFE tape or apply pipe dope on the male threads, hand-tighten the cap, then turn one to two full turns with a wrench; the common mistake is skipping the sealant and relying on the galvanized finish alone.

What maintenance will the galvanized malleable iron cap need over time?

Inspect the threads and exterior for white rust or pitting annually; if the galvanized coating is breached, replace the cap because the underlying iron will corrode quickly.

What pressure limit applies to this Class 150 fitting under sustained use?

The Class 150 rating defines the maximum working pressure; sustained pressure above that limit will cause the cap to fail first.
