Tech Products 51552-5 Vibration Isolator 1815 Lb Stud Mount

Product Description

The TECH PRODUCTS 51552-5 is a stud-to-stud vibration isolator rated for a maximum load capacity of 1,815 pounds. This round, rubber-style mount dampens vibration and absorbs mechanical shock between equipment and mounting surfaces, reducing noise transmission and structural fatigue. At 3.125 inches in diameter and 1.5 inches in height, with a 1/2-13 threaded stud configuration and a thread length of 1.625 inches, it is sized for heavy-duty mechanical installations. HVAC technicians, plumbers, and millwrights install this type of isolator under compressors, pumps, air handlers, and similar vibrating equipment.

This isolator is suited for residential and light commercial applications where rotating or reciprocating equipment requires vibration control at the mounting point. Typical install scenarios include rooftop condenser units, base-mounted pump sets, and mechanical equipment pads where transmitted vibration must be limited to protect the structure and connected piping or ductwork. The stud-to-stud design allows direct in-line installation without additional hardware beyond the mating fasteners.

Compatibility

Designed as an OEM-style replacement or direct-fit vibration isolator for heavy-duty mechanical equipment requiring a 1/2-13 stud-to-stud mount with a maximum load rating of 1,815 pounds.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors during equipment commissioning or service. Power down and de-energize all associated equipment before removing or replacing isolators. Ensure the load per mount does not exceed the 1,815 pound rated capacity, and verify that all studs are fully threaded and torqued to the equipment manufacturer's fastener specifications. Inspect mounting surfaces for flatness and condition before installation to ensure proper load distribution.
