Reducing Coupling Details
This malleable iron reducing coupling connects a 3/4 inch female NPT pipe to a 3/8 inch female NPT pipe. It is rated for Schedule 80 piping systems and carries a Class 300 pressure rating. The fitting handles a maximum operating pressure of 2,000 psi at 150 degrees Fahrenheit. It is supplied new and ready for installation.
Suitable Installations
This coupling suits plumbers and maintenance teams joining dissimilar pipe sizes in high-pressure water, oil, or gas lines that require Class 300 strength. It is not for systems exceeding the stated pressure or temperature limits. Installers needing a straight coupling, a different material, or a lower pressure class should select another fitting.
Deciding Specification
The critical specification is the 3/4 inch to 3/8 inch female NPT reduction combined with the Class 300 rating for Schedule 80 pipe. Verify that your system operates at or below 2,000 psi at 150 degrees Fahrenheit and uses these exact thread sizes before purchasing.

Questions about this item
What pipe schedule must I already have for this Class 300 reducer coupling to thread on correctly?
It is made for Pipe Schedule 80, so your existing 3/4 in and 3/8 in pipes need to be that schedule for the NPT threads to seal.
Will the 3/8 in female NPT end mate with older iron pipe I want to keep in the system?
Yes, the 3/8 in female NPT thread follows the same standard used on older iron pipe, so it will connect directly without adapters.
How can I verify the joint is holding at the rated 2,000 psi after installation?
Pressurise the line up to 2,000 psi at no more than 150 °F and check for leaks; the coupling is rated for that maximum operating pressure.
