Matco-norca b-rc0502 Brass Reducing Coupling 1x3/8 in

Product Description

The MATCO-NORCA b-rc0502 is a brass reducing coupling designed to connect pipes of two different diameters in threaded plumbing and mechanical systems. It transitions from a 1 inch female thread on the larger end to a 3/8 inch female thread on the smaller end. Constructed from brass, this coupling provides solid corrosion resistance and reliable sealing in a wide range of fluid-handling applications. Licensed plumbers and mechanical contractors install this type of fitting when a pipe run must change diameter at a joint without additional adapters or unions.

This reducing coupling is suited for residential and light commercial plumbing, hydronic heating, compressed air, and similar threaded piping systems where a direct pipe-size reduction is needed at a coupling point. It is appropriate for use in water supply lines, distribution manifolds, and equipment connections that require a transition from 1 inch to 3/8 inch pipe thread.

Key Features

• Reduces from 1 inch to 3/8 inch in a single fitting, eliminating the need for a separate adapter
• Brass construction provides corrosion resistance suitable for water, air, and compatible fluid service
• Threaded connection type for standard NPT installation with no special tooling
• Compact coupling profile keeps the piping assembly tight and low-profile

Compatibility

Designed as an OEM-style replacement or new-installation brass reducing coupling for standard 1 inch x 3/8 inch threaded pipe connections in residential and commercial plumbing and mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber in accordance with applicable local plumbing codes and IPC guidelines. Shut off the water supply and relieve system pressure before removing or installing any threaded fitting. Apply thread sealant tape or paste to the male threads before assembly and tighten to snug with a pipe wrench, avoiding overtightening that can crack brass fittings. Inspect for leaks after restoring system pressure.
