Brass Reducer 1/2" x 3/8" FNPT x MNPT

This brass reducer connects a 1/2-inch female NPT thread to a 3/8-inch male NPT thread. It suits plumbing, hydraulic or pneumatic systems that require a step-down in pipe size. The fitting meets NSF 61 Annex G standards for drinking-water contact and carries a 1200 psi pressure rating. Operating temperature range spans from -65°F to 250°F.

Verify Threads and Pressure Before Installing

Confirm that both mating ports use National Pipe Taper threads and that the system pressure will not exceed 1200 psi. The fitting length is 1 13/64 inches with a 1-inch outside diameter and a 15/16-inch hex for wrench engagement. Ensure the fluid media is compatible with brass and the temperature stays within the rated range. Apply suitable thread sealant rated for the service conditions.

For Installers Reducing NPT Pipe Sizes in Potable

This reducer suits plumbers, maintenance technicians and OEM assemblers who need a lead-free brass transition between 1/2-inch and 3/8-inch NPT connections. It is not intended for applications requiring a larger step-down, a different thread standard or a material other than brass. Buyers needing a union, elbow or tee configuration should select the appropriate fitting type instead.

Questions about this item

Does the box include any thread sealant or tape for the 1/2 in FNPT x 3/8 in MNPT connections?

The fitting is supplied as a single brass reducer; thread sealant or PTFE tape must be purchased separately to seal the tapered NPT threads.

When should I choose the 1/2 in x 3/8 in size over other reducer dimensions?

Select this reducer when you need to step down from a 1/2 inch female NPT port to a 3/8 inch male NPT pipe or component in the same line.

What does the 1200 psi rating mean for a typical plumbing installation?

It indicates the maximum non-shock pressure the brass body is rated to contain at temperatures up to 250 °F, well above normal residential supply pressure.
