Nvent 4550125PL Malleable Split Ring Hanger 1-1/4 in

Product Description

The NVENT 4550125PL is a malleable iron split ring hanger designed to support 1-1/4 inch pipe with a 1.66 inch outside diameter. It accepts a 3/8 inch threaded rod for overhead suspension and ships in a plain (uncoated) finish. Split ring hangers are a standard fastening component in mechanical piping systems, used to cradle and suspend pipe from structural members or framing. Licensed plumbers, pipefitters, and mechanical contractors install these as part of rough-in work on water supply, hydronic heating, and general-purpose piping runs.

The 4550125PL is suited for residential and light commercial piping installations where 1-1/4 inch pipe requires secure overhead or below-deck support. The malleable iron construction handles the mechanical loads typical of supported pipe spans in both horizontal and vertical orientations. The plain finish is appropriate for interior dry environments. Where corrosion resistance is required, installers should select a coated or electro-galvanized variant instead.

Key Features

• Fits 1-1/4 inch nominal pipe with a 1.66 inch outside diameter
• Accepts standard 3/8 inch threaded suspension rod
• Malleable iron construction provides strength and resistance to impact during installation
• Plain finish suitable for interior dry applications
• Split ring design allows installation around pipe without threading from an end

Compatibility

Designed for use with 1-1/4 inch nominal pipe at 1.66 inch outside diameter on standard 3/8 inch threaded rod hanger assemblies in residential and commercial mechanical piping systems.

Installation Notes

Shut off and depressurize the piping system before making any hanger adjustments or modifications to supported runs. Secure the threaded rod to an appropriate structural anchor rated for the load before attaching the hanger. Follow IPC and local mechanical code requirements for maximum support spacing based on pipe material and size. A licensed plumber or pipefitter should perform installation in systems subject to code inspection.
