Nibco PRES90L34 Copper Press 90 Degree Elbow 3/4 in

Product Description

The NIBCO PRES90L34 is a 3/4-inch copper press-fit 90 degree elbow designed for use in pressurized plumbing and hydronic systems. It connects two copper pipe runs at a right angle using a press-fit joining method, eliminating the need for open flame or soldering during installation. The fitting accepts 3/4-inch pipe on both ends in a press x press configuration. It is installed by licensed plumbers and pipefitters working on new construction or retrofit projects where flame-free joining is required or preferred.

This elbow is suited for residential and light commercial plumbing systems, including domestic water supply and hydronic heating applications. The press-fit design makes it a practical choice in occupied buildings, tight spaces, or any job site where torch work creates a safety or code concern. Both ends are press connections, so a compatible press tool and correct jaw set for 3/4-inch copper are required to complete the joint.

Key Features

• 3/4-inch press x press end connections for tool-based, flame-free joining
• 90 degree elbow geometry for right-angle direction changes in pipe runs
• Copper construction for durability and compatibility with potable water systems
• No soldering or torch required, reducing fire risk during installation
• Compact fitting profile suitable for use in confined spaces

Compatibility

Designed as an OEM-style press-fit replacement fitting compatible with standard 3/4-inch copper pipe in press-fit plumbing systems.

Installation Notes

Installation must be performed by a qualified plumber using a press tool equipped with the correct jaw size for 3/4-inch copper press fittings. Shut off and depressurize the water supply and ensure the pipe and fitting are clean and dry before pressing. Verify that the fitting is fully seated on the pipe before actuating the press tool. Follow all applicable local plumbing codes, including IPC requirements for press-fit copper joints.
