Product Description

The TECH PRODUCTS 51551-3 is a heavy-duty plate/stud vibration isolator rated for a maximum load of 760 pounds. This round isolator measures 3.125 inches in diameter and 1.5 inches in height, with a 1/2-13 stud thread and a thread length of 1.625 inches. It is designed to absorb and dampen mechanical vibration in HVAC equipment, compressors, pumps, fans, and other industrial or commercial machinery. Installation is performed by HVAC technicians, pipefitters, or mechanical contractors as part of equipment mounting and vibration isolation procedures.

This isolator is suited for residential and commercial applications where controlling equipment vibration is required. Typical use cases include base mounting of rooftop units, air handlers, condensing units, pumps, and similar rotating or reciprocating equipment. The plate/stud mount design allows for secure attachment to both equipment bases and structural mounting surfaces, making it adaptable across a range of mechanical installations.
