Hailiang HLGPEX-101-0159 Brass Pex X Mpt Adapter 1x3/4 in

Product Description

The HAILIANG HLGPEX-101-0159 is a lead-free brass insert-style adapter designed to connect 1-inch PEX tubing to a 3/4-inch male pipe thread (MPT) fitting. This type of fitting is a standard transition component in PEX-based plumbing systems, allowing a PEX run to terminate or connect at a threaded male port on valves, manifolds, water heaters, or other threaded fixtures. Constructed from brass, it offers reliable corrosion resistance and durability in both hot and cold water supply applications. Licensed plumbers and experienced plumbing contractors install this fitting during new construction and retrofit work.

This adapter is suited for residential and light commercial plumbing systems where PEX tubing is used for water distribution. The insert end slips inside the PEX tube and is secured with a crimp ring or clamp ring using the appropriate tool, while the MPT end threads directly into a female-threaded port. Its lead-free brass construction meets requirements for potable water systems, making it appropriate for drinking water supply lines, hot and cold distribution, and similar applications.

Key Features

• Lead-free brass construction suitable for potable water supply systems
• Insert-style PEX end compatible with standard crimp ring or clamp ring installation methods
• 1-inch PEX inlet transitions to 3/4-inch male pipe thread outlet
• Designed for use in hot and cold water distribution plumbing
• Corrosion-resistant brass body for long-term durability in wet environments

Compatibility

Designed as an OEM-style replacement or new-installation fitting for residential and light commercial PEX plumbing systems requiring a transition from 1-inch PEX tubing to a 3/4-inch male pipe thread connection.

Installation Notes

Installation is performed by a licensed plumber. Shut off the water supply and relieve system pressure before beginning work. The insert end requires a properly sized PEX crimp ring or clamp ring and the corresponding crimp or clamp tool to achieve a watertight connection. Thread the MPT end into the female-threaded port using an appropriate thread sealant or tape in accordance with local plumbing codes and IPC guidelines.
