Anvil Malleable Iron Reducer Coupling

This Anvil 0310087408 reducer coupling joins a 1 in pipe to a 1/4 in pipe using FNPT threads. It is built for plumbing systems that require a durable transition between different pipe diameters. The malleable iron construction suits residential and commercial drainage installations. Class 150 rating supports standard pressure requirements.

Class 150 Malleable Iron Build Quality

The fitting meets ASME B 16.3 standards and carries UL and FM approvals for code compliance. Malleable iron resists cracking under mechanical stress and vibration in drain lines. Rated for 300 psi at 150 degrees F and 150 psi saturated steam at 350 degrees F. Operating temperature range spans -20 degrees to 350 degrees F for varied service conditions.

FNPT Threaded Connection Practicality

Female National Pipe Taper threads on both ends allow direct assembly with matching male-threaded pipe or fittings without additional adapters. The 1 in by 1/4 in size reduction handles significant diameter changes in a single component. No gaskets or sealant are included, so installers must supply thread sealant separately. Suitable for new installations or repair work where threaded joints are specified.

Questions about this item

What does the Class 150 rating limit in practice?

The Class 150 rating caps the fitting at 300 psi at 150 degrees F for water and 150 psi at 350 degrees F for saturated steam.

What thread type and sizes must the mating pipes have to fit this reducer?

The fitting uses FNPT threads on both ends, with a 1 inch female thread on one side and a 1/4 inch female thread on the other.

How is this coupling installed and what step is often missed?

Apply thread sealant to the male pipe threads, then tighten the pipes into the female NPT ends; the step often missed is using a compatible sealant rated for the 350 degree F temperature range.
