Nvent 4550075PL Split Ring Hanger 3/4 in 180 Lb

Product Description

The NVENT 4550075PL is a swivel-loop split ring hanger designed to support 3/4 inch pipe from 3/8 inch threaded rod in mechanical, plumbing, and HVAC piping systems. Cast iron construction provides solid load-bearing performance up to 180 pounds, making it appropriate for a wide range of commercial and residential pipe support applications. The swivel-loop design allows for angular adjustment during installation, reducing the need for precise rod alignment before the hanger is set. This fitting is installed by licensed plumbers, pipefitters, and HVAC mechanics as part of overhead pipe support assemblies.

The 4550075PL is suited for use in overhead piping runs where 3/4 inch pipe must be suspended from structural members using 3/8 inch threaded rod. Typical applications include domestic water distribution, HVAC hydronic piping, refrigerant suction and liquid lines, and general mechanical piping. The maximum outside diameter accommodated is 1 1/16 inches. This hanger is used in both new construction and retrofit installations across light commercial and residential mechanical systems.
