3/4 inch PEX Press Bronze Insert Adapter Crimp x Press

3/4" PEX Press Bronze Adapter – Crimp x Press Connection

The 3/4 inch PEX Press Bronze Insert Adapter is designed to transition between ASTM F1807 crimp connections and press-fit copper assemblies. Constructed from lead-free bronze, this adapter combines a barbed PEX insert connection with a press fitting end to enable reliable system transitions in potable water and hydronic applications. It is suitable for joining cross-linked polyethylene tubing (PEX) to press-connect copper piping networks in residential and light commercial systems.

Product Features

• ✅ Connection Type: Crimp (ASTM F1807) x Press (copper press, typically with EPDM sealing element)
• ✅ Material: Lead-free bronze, compliant with NSF/ANSI 61 and 372 for potable water use
• ✅ Application: For use in PEX-to-copper transitions without the need for soldering or open flame
• ✅ Design: Precision-machined barbs and press geometry ensure secure mechanical retention and leak resistance

Technical Specifications

• Nominal Size: 3/4 inch
• End A: PEX Insert – crimp/squeeze compatible with ASTM F1807/F2159 standards
• End B: Press connection compatible with standard copper press tools and jaws (typically “V” profile)
• Working Pressure: Typically rated up to 200 psi at 73°F; consult manufacturer for specific pressure/temperature limits
• Material Standard: Manufactured per ASTM F877, F1807, and press fitting performance requirements

Installation Requirements

Install the PEX end using a copper crimp ring or stainless steel clamp per ASTM standard. The press end requires an approved press tool and compatible jaws. Always verify pipe insertion depth and use manufacturer-recommended sealing elements and tools. Confirm system pressure ratings after installation and conduct standard pressure testing as required by code.

Common Applications

This adapter is typically used in:

• Potable water supply systems transitioning from PEX tubing to copper press fittings
• Retrofit or repair scenarios replacing soldered joints with flame-free connections
• Hydronic heating loops and manifold outlet assemblies

Regulatory Compliance

Lead-free bronze fittings are required by U.S. federal law for all potable water systems. This adapter complies with national plumbing codes and is certified for use in drinking water applications when installed per manufacturer guidelines.

The 3/4" PEX Press Bronze Adapter provides a reliable, code-compliant method for joining dissimilar piping systems. Its durable construction and dual-connection design simplify system layout while supporting long-term mechanical integrity under typical residential service conditions.
