Zsi UB1/2PA6 U-bolt Clamp Cushion 1/2 in Pipe 316 Ss

Product Description

The ZSI UB1/2PA6 is a cushioned U-bolt pipe clamp constructed from 316 stainless steel, designed to secure 1/2-inch nominal pipe runs in corrosive or high-moisture environments. It delivers a rated load capacity of 485 pounds, making it suitable for demanding mechanical, plumbing, and process piping applications. The integrated cushion isolates the pipe from direct metal contact, reducing vibration transmission and protecting pipe surfaces from abrasion. Plumbers, pipefitters, and mechanical contractors install this clamp where corrosion resistance and load integrity are both required.

This clamp is used in residential and commercial piping systems where 1/2-inch pipe must be anchored to structural panels or framing. The 316 stainless steel construction makes it well suited for marine, coastal, chemical processing, and other environments where standard carbon steel or 304 stainless would face accelerated corrosion. The maximum panel thickness it accommodates is 1/2 inch, which should be confirmed against the mounting surface before installation.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh and wet environments
• 485-pound load capacity supports secure, code-compliant pipe support spans
• Integrated cushion reduces vibration transfer and protects pipe exterior from metal-to-metal contact
• Fits 1/2-inch nominal pipe size for compatibility with common small-diameter piping runs
• Maximum panel thickness of 1/2 inch suits standard structural mounting surfaces

Compatibility

Designed for use with 1/2-inch nominal pipe and mounting panels up to 1/2 inch thick. Suitable as a direct replacement or new-installation U-bolt clamp in mechanical, plumbing, and process piping systems requiring 316 stainless steel construction.

Installation Notes

Installation is typically performed by licensed plumbers or pipefitters in accordance with applicable mechanical and plumbing codes such as the IPC or IFGC. Shut off the relevant fluid or gas supply and depressurize the line before securing or repositioning any pipe support. Confirm the mounting surface panel thickness does not exceed 1/2 inch before fastening. Do not overtighten the U-bolt hardware, as this can compress the cushion unevenly and reduce its vibration-damping effectiveness.
