Value Collection A3-21.3 Insert Vibration-control Clamp

Product Description

The VALUE COLLECTION A3-21.3 is a bolt-down insert vibration-control clamp designed for 1/2 inch pipe. It isolates pipe movement and dampens vibration in mechanical systems where pipe lines pass through structural supports or framing. The clamp body is molded from polypropylene for corrosion resistance, while the mounting plate is steel for rigid attachment to a substrate. At 0.01 pounds, it is a lightweight single-unit fastener suited for high-density installations in plumbing, HVAC, and mechanical piping runs.

This clamp is used in residential and light commercial applications wherever 1/2 inch pipe requires secure, vibration-dampening support at a fixed mounting point. Typical installations include copper or plastic supply lines in walls, ceilings, and mechanical rooms. The bolt-down mount style allows the clamp to be fastened directly to structural members, unistrut, or equipment frames. Licensed plumbers and HVAC mechanics install this type of clamp as part of code-compliant pipe support spacing per IPC and IMC guidelines.

Compatibility

Designed as an OEM-style replacement and standard insert vibration-control clamp for 1/2 inch pipe in residential and light commercial plumbing and mechanical piping systems.

Installation Notes

Installation is typically performed by a licensed plumber or mechanical contractor. Depressurize and drain the pipe line before making any support modifications. Secure the steel mounting plate to a structural member or framing with appropriately rated hardware before inserting the pipe into the clamp body. Follow IPC and IMC pipe support spacing requirements for the pipe material and application.
