SKU CH-453M-9K3C5

Forged steel cap with 2 in female NPT rated Class 3000 for 2,000 psi at 150 °F and 300 psi steam at 550 °F

  • Forged steel construction withstands 3000 psi design pressure
  • Female NPT threads accept standard 2 inch pipe connections
  • Rated for 2000 psi at 150 degrees F operating conditions
  • Handles 300 psi steam pressure up to 550 degrees F
  • Service temperature range from minus 20 to 550 degrees F

2-inch Class 3000 forged steel cap

This black forged steel cap fits 2-inch nominal pipe size systems and carries a Class 3000 rating. It uses female NPT threads and is supplied without pre-applied thread sealant or an included seal. The solid plug construction closes the end of a pipe run in industrial plumbing installations. It is intended for installers who need a pressure-rated closure for steel piping.

Rated for 2,000 psi at 150 °F

The fitting holds 2,000 psi at 150 °F and 300 psi saturated steam at 550 °F across a service range of -20 °F to 550 °F. These limits apply to sustained operating conditions rather than short pressure spikes. The forged steel body maintains strength through thermal cycling in steam and high-pressure water lines. It is not suited for systems that exceed these pressure-temperature combinations.

Female NPT threads with no sealant included

The single specification that decides fit is the female NPT thread form on a 2-inch nominal bore. Mismatched thread standards or pipe schedules will leak or crack under the rated pressure. Buyers who need a different thread type, a larger bore or an integrated seal must select another fitting.

Questions about this item

How hot does the 2 in forged steel cap get when the system runs continuously at 2,000 psi and 150 °F?

The cap is rated for continuous service at 2,000 psi and 150 °F, so its temperature will match the fluid temperature under those conditions.

What pipe thread must the installer provide for the female NPT cap to seal properly?

A matching 2 in male NPT pipe end is required for the cap to thread on and seal.

Will the Class 3000 cap hold up on an older black steel line that sees 300 psi steam at 550 °F?

Yes, the cap is rated for 300 psi steam at 550 °F, matching the limits of traditional black steel piping.
