Nibco 9055455PCU Copper Press 90 Degree Elbow 1/2 Inch

Product Description

The NIBCO 9055455PCU is a 1/2-inch Copper Press x Press 90-degree elbow designed for flameless press-joining systems used in commercial and residential plumbing and mechanical applications. This fitting eliminates open-flame soldering, making it a practical choice for retrofit and new construction work where hot-work permits are restricted or undesirable. It is rated for 200 psi cold working pressure (CWP) and handles a temperature range of -20 degrees F to 250 degrees F. Licensed plumbers and mechanical contractors install this fitting using compatible press tools and jaw sets sized for 1/2-inch copper press connections.

This elbow is suited for a wide range of fluid and gas service applications including potable water (hot and cold), hydronic heating, chilled water, compressed air, non-medical gases, low-pressure steam, and vacuum systems. It is approved for both above-ground and below-ground installations where permitted by local code. The press-fit design makes it well suited for tight spaces and situations where torch access is limited or prohibited.

Installation Notes

Installation must be performed by a licensed plumber using a compatible press tool and the correct 1/2-inch jaw or ring set for copper press fittings. Shut off the water supply and depressurize the system before beginning any fitting work. Verify that the pipe end is clean, deburred, and fully inserted to the fitting stop before pressing. Always confirm that the installed fitting meets local plumbing code requirements, including IPC and applicable ASTM standards, before returning the system to service.
