Taper Tapped Merchant Coupling

This forged steel coupling connects two 1 1/2 inch female NPT threads in Schedule 80 piping systems. It is built to Class 300 pressure ratings for industrial and commercial plumbing installations. The black finish identifies the carbon steel construction used in high-pressure service.

Fit for high-pressure steam or water lines

Suitable for installers joining Schedule 80 pipe where a 500 psi rating at 150 degrees F is required. Not intended for low-pressure residential drainage or systems using thinner wall schedules. Buyers needing welded or flanged connections should look at alternative fitting types.

Class 300 pressure rating

The coupling withstands 500 psi at 150 degrees F, which determines whether it meets the design pressure of the piping system. Verify the operating temperature and pressure against this limit before specifying the part.

Questions about this item

Will the forged steel coupling need periodic replacement due to corrosion or wear?

The coupling is made from forged steel rated for Schedule 80 pipe and Class 300 service, so under normal conditions it does not require scheduled replacement.

What pressure limit will be reached first during continuous high-pressure operation?

The maximum operating pressure is 500 psi at 150 degrees F, which is the primary limit under sustained use.

Does the coupling generate heat or noise when installed in a system running all day?

As a static forged steel fitting with no moving parts, it produces no noise and negligible heat during continuous operation.
