Nibco PRES90L1 Copper Press 90 Degree Elbow 1 Inch

Product Description

The NIBCO PRES90L1 is a 1-inch copper press-fit 90-degree elbow designed for use in pressurized plumbing and hydronic systems. This fitting connects two copper pipe runs at a right angle using a press-style connection, eliminating the need for open flame or soldering during installation. It is rated for use in potable water, heating, and cooling distribution systems. Licensed plumbers and pipefitters install this fitting using a compatible press tool and jaw set sized for 1-inch connections.

This elbow is suited for residential and light commercial plumbing systems where press-fit copper connections are specified. Typical applications include domestic hot and cold water distribution, radiant heating loops, and chilled water piping. The press-fit design makes it well-suited for retrofit and new construction work in areas where open flame is restricted or impractical, such as occupied buildings or tight mechanical spaces.

Key Features

Installation Notes

Installation is performed by licensed plumbers using a calibrated press tool with a 1-inch jaw set appropriate for copper press fittings. Shut off and depressurize the water supply before cutting into any existing line. Verify pipe ends are clean, round, and deburred before seating the fitting for pressing. Follow local plumbing codes and manufacturer tooling requirements to ensure a leak-free pressed joint.
