Sioux Chief 517-i137pk2 Cushion Pipe Clamp 1-1/4 in

Product Description

The SIOUX CHIEF 517-i137pk2 is a cushion pipe clamp designed for securing copper tubes and pipes in plumbing and mechanical systems. Built to the 517-I Series standard, it features a 12-gauge carbon steel body with a thermoplastic elastomer (TPE) cushion insert that isolates the pipe from the clamp, reducing vibration transmission and protecting the pipe surface. The clamp carries a 600-pound load capacity and is rated for temperatures from -65 to 275 degrees F, making it suitable for a wide range of hot and cold water piping applications. Licensed plumbers and pipefitters install this clamp in residential and commercial settings wherever strut channel support systems are used.

This clamp is intended for use with copper tubes and pipes at a 1-inch nominal pipe size, corresponding to a 1-3/8-inch outside diameter. It mounts directly to standard strut channel using a 5/16-18 x 1-1/4-inch bolt, integrating cleanly into unistrut-style support frameworks common in mechanical rooms, utility spaces, and above-ceiling plenum runs. The 1-1/4-inch trade size designation identifies the appropriate application range for this clamp within the 517-I Series lineup.

Key Features

• 600-pound load capacity supports heavy piping runs without deformation
• TPE cushion insert reduces vibration transfer and protects copper pipe surface
• 12-gauge carbon steel body provides structural rigidity
• Temperature rated from -65 to 275 degrees F for hot and cold water service
• Strut channel mounting with 5/16-18 x 1-1/4-inch bolt for compatibility with standard unistrut systems
• 1-3/8-inch OD sizing fits 1-inch nominal copper pipe

Compatibility

Designed for use with copper tubes and pipes at 1-inch nominal pipe size (1-3/8-inch OD). Mounts to standard strut channel framing systems.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off the water supply and depressurize the line before positioning clamps on active piping systems. Secure the clamp to strut channel with the specified 5/16-18 bolt and ensure the TPE cushion is fully seated around the pipe before tightening. Follow applicable IPC and local mechanical code requirements for pipe support spacing and hanger intervals.
