Sioux Chief 490-10542 Sponge Cushion Rubber Ring

Product Description

The SIOUX CHIEF 490-10542 is a sponge cushion rubber ring designed to isolate and support pipes in residential and commercial plumbing installations. Measuring 5.375 inches by 3.5 inches by 0.75 inches, this ring fits between a pipe and its hanger or bracket to absorb vibration, reduce noise transmission, and prevent metal-to-metal contact. The sponge rubber construction compresses slightly under load, conforming to the pipe surface and distributing clamping pressure evenly. Plumbers and pipefitters install this ring as part of a complete pipe support assembly where acoustic isolation or surface protection is required.

This cushion ring is suited for use in pipe hanger and support assemblies in residential, commercial, and light industrial plumbing systems. It is commonly installed on copper, plastic, and steel pipe runs where vibration dampening and noise reduction are priorities. Typical applications include supply lines, drain lines, and mechanical room piping where pipes are anchored to structural members and vibration transfer to the building structure must be minimized.

Key Features

• Sponge rubber construction absorbs pipe vibration and reduces noise transmission to building structure
• Dimensions of 5.375 x 3.5 x 0.75 inches suit standard pipe hanger assemblies
• Compressible material conforms to pipe surface for even load distribution
• Prevents direct metal-to-pipe contact, protecting pipe surface finish
• Suitable for use with copper, plastic, and steel pipe

Compatibility

Designed as an OEM-style cushion insert for standard residential and commercial pipe hanger and support assemblies requiring vibration isolation.

Installation Notes

Installation is performed by licensed plumbers or pipefitters as part of a pipe support or hanger assembly. Shut off the relevant water supply or isolate the pipe section before adjusting or repositioning hangers. Position the cushion ring between the pipe and the hanger bracket so the ring fully seats around the pipe circumference. Follow IPC and local plumbing code requirements for support spacing and hanger type.
