Nibco PRES90L34-JAR Copper Press 90 Degree Elbow 3/4 in 15 Pack

Product Description

The NIBCO PRES90L34-JAR is a 3/4-inch copper press 90-degree elbow sold in a 15-pack configuration for professional jobsite use. This fitting connects two copper pipe runs at a right angle using a press-style connection — no open flame, no soldering, no flux. The press joint is made by crimping the fitting onto the pipe with a compatible press tool, creating a watertight mechanical seal. Plumbers and pipefitters use this fitting in potable water, hydronic heating, and commercial plumbing systems where speed and flame-free installation are required. The 15-pack format suits rough-in work where multiple changes of direction are needed.

This elbow is suited for residential and light commercial plumbing applications including domestic hot and cold water supply, radiant heating distribution, and mechanical room piping. The press-style end connections on both ends allow back-to-back installations in tight spaces without the clearance requirements of a torch setup. It is a practical choice in occupied buildings or areas where open flame is restricted by code or facility policy.

Key Features

• 3/4-inch Press x Press end connections on both ends for tool-crimped, solder-free joints
• 90-degree elbow geometry for right-angle directional changes in copper pipe runs
• Copper construction compatible with standard copper press tooling and jaws
• 15-pack quantity reduces per-unit cost on multi-elbow rough-in projects
• Flame-free installation suitable for occupied structures and flame-restricted work zones

Compatibility

Designed as an OEM-style press fitting for use with 3/4-inch copper pipe systems following ASME B16.18 or B16.22 dimensional standards. Press fittings require a compatible press tool and correct jaw size for the connection to be valid.

Installation Notes

Installation is performed by licensed plumbers using a compatible hydraulic or battery-powered press tool fitted with the correct 3/4-inch jaw set. Shut off the water supply and depressurize the line before cutting into an existing system. Pipe ends must be cut square, deburred, and cleaned before inserting into the fitting to the full depth mark. Verify each pressed joint with the tool indicator before restoring pressure, in accordance with local plumbing code requirements.
