1/2 Inch Forged Steel Pipe Cap

This black forged steel cap fits a 1/2 inch nominal pipe size with female NPT threads. It is designed to seal the end of a pipe run in plumbing or piping systems. The forged construction provides mechanical strength for pressure applications. The product is supplied new from Zoro Select.

Female NPT Threads and Forged Build

The female National Pipe Taper threads create a tapered seal when mated with a male threaded pipe or fitting. Forged steel resists cracking and deformation under stress better than cast alternatives. The black finish offers a baseline layer of corrosion resistance. No pre-applied thread sealant or separate seal is included with the cap.

Verify Thread Compatibility and Sealant Needs

Confirm that the mating component uses male NPT threads of the same nominal size before ordering. Because no sealant is pre-applied, you must supply thread tape or pipe dope appropriate for the system media. Ensure the pressure rating of the cap matches the requirements of your piping system. Orders of $75 or more ship free.
