Reducing Coupling 2 in to 1 1/4 in NPT

This malleable iron reducing coupling joins a 2 inch NPT female thread to a 1 1/4 inch NPT female thread. It is rated for Class 150 service and carries a galvanized finish. Plumbers and maintenance crews use it to step down pipe sizes in water, air or gas lines.

Galvanized Class 150 rating

The galvanized coating resists corrosion in damp or outdoor installations. Class 150 pressure rating suits standard low-pressure plumbing and compressed-air systems. Malleable iron construction provides mechanical strength for threaded connections that must withstand vibration or thermal cycling.

Check thread compatibility and chemical warnings

Verify that both mating pipes use NPT threads with 11 1/2 threads per inch. The product carries California Proposition 65 warnings for chemicals known to cause cancer and reproductive harm. Confirm local code acceptance for galvanized malleable iron in the intended fluid service before ordering.

Questions about this item

Will the galvanized coating on this malleable iron coupling need replacement later?

The galvanized finish protects the malleable iron from corrosion under normal plumbing conditions; no scheduled recoating is required.

What pressure limit appears first during sustained use of this Class 150 fitting?

The Class 150 rating sets the maximum working pressure at 150 psi, which is the governing limit for continuous service.

Does this reducing coupling generate noise, heat or extra power draw when installed in a line running all day?

As a passive threaded fitting with no moving parts or electrical connection, it produces no noise, heat or power consumption.
