Comfort Pro Systems 37582 Pex X Mpt Brass Adapter

Product Description

The COMFORT PRO SYSTEMS 37582 is a brass adapter designed to connect 1-inch PEX tubing to a 3/4-inch male pipe thread (MPT) fitting. It serves as a transition point between flexible PEX lines and threaded pipe connections in residential and light commercial plumbing systems. The all-brass construction provides corrosion resistance and durability under typical domestic water pressure conditions. Plumbers and pipefitters install this adapter when transitioning from PEX distribution lines to threaded valves, manifolds, or fixture supply connections. Its straightforward design keeps installation time low and ensures a reliable, leak-resistant joint.

This adapter is suited for hydronic heating systems, domestic hot and cold water distribution, and radiant floor heating installations where PEX tubing terminates at a threaded component. It is sold as a single unit, making it easy to order exact quantities for a job. The 1-inch PEX side accommodates standard crimp or clamp-ring connections, while the 3/4-inch MPT end threads directly into compatible female-threaded fittings, valves, or manifold ports.

Key Features

• Brass construction for corrosion resistance in potable water and hydronic applications
• 1-inch PEX connection compatible with standard crimp and clamp-ring tooling
• 3/4-inch male pipe thread (MPT) end for direct connection to female-threaded fittings
• Compact adapter design minimizes transition length in tight spaces
• Sold as a single unit for precise quantity ordering

Compatibility

Designed as an OEM-style replacement and standard-use adapter for PEX-to-threaded-pipe transitions in residential and light commercial plumbing and hydronic heating systems.

Installation Notes

Installation is performed by a licensed plumber or qualified pipefitter. Shut off the water supply and relieve system pressure before making any connections. Apply thread sealant tape or pipe dope to the MPT threads before threading into the female fitting; do not overtighten, as brass threads can strip. The PEX end requires a properly sized crimp ring or clamp ring and the appropriate installation tool to achieve a code-compliant, leak-free connection per IPC and local plumbing code requirements.
