Class 300 Reducer Coupling

This malleable iron reducing coupling connects a one inch female NPT pipe to a half inch female NPT pipe. It is rated for Schedule 80 piping systems and carries a Class 300 pressure class. The fitting is designed for drain component installations where a secure, threaded transition is required.

Installers needing a high pressure threaded

Plumbers and maintenance technicians working with Schedule 80 systems will find this coupling matches the required pressure class and thread standard. It is not suited for installers who need a straight coupling, a different thread type, or a fitting rated for a lower pressure class.

2000 psi at 150 Degrees F maximum operating pressure

The coupling withstands two thousand psi at one hundred fifty degrees Fahrenheit, making it appropriate for high pressure drain lines operating within that limit. Systems exceeding this pressure or temperature rating require a differently rated fitting.

Questions about this item

What pipe schedule must the existing piping be for this Class 300 reducer coupling to seal properly?

The coupling is rated for Pipe Schedule 80, so the connecting pipes should match that wall thickness for correct engagement.

Can this malleable iron coupling handle the pressure and temperature of an older steam line running near its 2,000 psi limit?

It is rated for 2,000 psi at 150 degrees F maximum operating pressure, so verify your system stays within both limits before installation.

How do I confirm the NPT threads on both the 1 in and 1/2 in ends are sealing without leaks after assembly?

Pressurise the line up to the 2,000 psi rating at no more than 150 degrees F and inspect both female NPT joints for any weeping or pressure drop.
