1 inch x 1 inch PEX Copper Reducing Insert Adapter PEX x Press

1" x 1" PEX x Press Adapter – Transition Fitting for Hybrid Plumbing Systems

The 1" x 1" PEX x Press Adapter provides a secure connection between PEX tubing and press-fit metal piping systems. Designed for potable water distribution, it enables reliable joining of dissimilar materials without compromising system performance. This fitting is intended for use in commercial, residential, and multi-family plumbing installations where flexibility and structural integrity are critical.

The adapter incorporates a press-connect end suitable for copper or stainless steel pipe systems and a PEX connection compatible with ASTM F1960 or F1807 specifications, depending on variant. Engineered to meet pressure and thermal requirements of modern water supply networks, it supports both new construction and retrofit applications.

Product Characteristics

• ✅ Material Compatibility – Designed to transition between PEX tubing and metal press systems in potable water applications.
• ✅ Secure Joint Design – Press connection ensures leak-resistant mechanical seals when installed with manufacturer-approved tools.
• ✅ Code-Conforming Construction – Manufactured in accordance with national and local plumbing standards for hybrid system transitions.
• ✅ Thermal and Pressure Tolerance – Rated for system conditions common to domestic hot and cold water service.
• ✅ Application Flexibility – Suitable for horizontal or vertical runs, risers, manifold connections, and tight-space retrofits.

Specifications

• Connection Type: 1" PEX x 1" Press
• Material: Dezincification-resistant brass or bronze body (varies by model)
• Applicable Standards: NSF/ANSI 61 and 372, UPC, IPC compliant
• Pressure Rating: Typically up to 200 PSI (verify based on configuration)
• Temperature Rating: Suitable for use from 33°F to 200°F (varies with PEX system)

Installation Considerations

This fitting must be installed using manufacturer-approved press tools for the press end and appropriate ASTM-compliant tools for the PEX connection. Ensure tubing is cut cleanly and inserted to marked depth. Press connections must be checked for proper alignment and verified after compression. All installations must conform to local plumbing and mechanical codes.

Common Use Scenarios

Frequently installed in hybrid piping systems where PEX distribution is integrated with copper or stainless risers, branch lines, or mechanical room manifolds. Ideal for renovations, phased upgrades, or crossover installations in areas with space constraints or multiple pipe types.

Material and System Note

PEX systems offer improved resistance to corrosion, scaling, and freeze damage. When combined with press technology, they allow for modular plumbing layouts and reduced installation labor in multi-zone or multi-story buildings.
