Tech Products 51253 Vibration Isolator 58 Lb 5/16-18 Stud

Product Description

The TECH PRODUCTS 51253 is a stud-to-stud vibration isolator rated for a maximum load capacity of 58 pounds. It measures 1 inch in diameter and 0.75 inches in height, with a 5/16-18 threaded stud mount on both ends. The round, compact design absorbs and dampens mechanical vibration at equipment mounting points, reducing noise transmission to supporting structures. This isolator is installed by HVAC technicians, mechanical contractors, and equipment service professionals wherever vibration control is required between a unit and its mounting surface.

This isolator is suited for residential and light commercial HVAC applications, including condensing units, fan coil units, compressor mounts, and small mechanical equipment bases. Its stud-to-stud configuration allows it to be threaded directly into equipment feet or mounting brackets without additional hardware. The 58-pound load rating makes it appropriate for individual mounting points on smaller equipment or as one of multiple isolators distributing a larger unit load.

Key Features

• 58-pound maximum load capacity per isolator
• 5/16-18 threaded stud on both ends for direct mount installation
• 1 inch overall diameter, 0.75 inches high - compact footprint for tight mounting clearances
• Round shape provides consistent radial vibration damping
• UNSPSC Code 23153100 - classified under mechanical vibration control hardware

Compatibility

Designed as an OEM-style replacement or service-install vibration isolator for residential and light commercial HVAC equipment and mechanical units with 5/16-18 stud mounting points and per-foot load requirements at or below 58 pounds.

Installation Notes

Installation is performed by licensed HVAC technicians or mechanical contractors. Power down and disconnect all electrical supply to the equipment before removing or replacing mounting hardware. Thread the isolator studs into the equipment foot and mounting bracket by hand first, then snug with a wrench - do not overtighten, as excessive torque can compress the isolator body beyond its designed working range. Verify load is distributed evenly across all isolators at the mounting points before returning the unit to service.
