3/4 inch PEX Copper 90 Degree Insert Elbow Crimp x Female Sweat Copper

3/4” PEX Crimp Elbow – Copper Insert x Female Sweat

The 3/4” PEX Crimp Elbow, featuring a copper insert x female sweat connection, is engineered to facilitate a 90-degree directional change between PEX tubing and copper pipe in potable water systems. Designed for use in pressurized residential and commercial plumbing applications, this fitting combines ease of installation with long-term reliability under varying temperature and pressure conditions.

The insert end connects to 3/4” PEX tubing using a copper crimp ring and ASTM F1807 compliant crimping tool, while the female sweat side accepts 3/4” nominal copper pipe for soldered connections. Its compact elbow geometry is well-suited for transitions in confined spaces or wall cavities, minimizing the need for additional fittings.

Application Guidelines

This fitting is used in water distribution systems where a 90° transition between PEX and copper is required. It is commonly installed in branch connections to fixtures, manifold routing systems, or when integrating legacy copper infrastructure into new PEX installations. Proper installation requires a PEX crimping tool and a heat source for sweat connection—either torch with solder or brazing, depending on the application and system requirements.

Best Practices for Installation

• Ensure tubing and pipe ends are cut square and free from debris before assembly.
• Use ASTM F1807 compatible copper crimp rings and tools for the insert connection.
• Apply heat evenly to the sweat side joint and allow for full solder penetration to ensure a leak-tight seal.
• Visually inspect all joints and test under pressure per code prior to covering or insulation.

Common Uses

• Potable water distribution systems
• Hot and cold water service lines
• Fixture branches and transition fittings in remodels
• Multi-family and single-family residential plumbing

Note

Lead-free brass and copper components are now required under the Reduction of Lead in Drinking Water Act (SDWA). This fitting is manufactured in full compliance and is marked accordingly for code enforcement verification.

The 3/4” PEX Crimp Elbow – Insert x Sweat provides a secure, code-compliant solution for mixed-material plumbing layouts. Use where durable, high-performance transitions are required in temperature- and pressure-regulated systems.
