Tech Products 51251 Stud Stud Vibration Isolator 44 Lb

Product Description

The TECH PRODUCTS 51251 is a stud-to-stud vibration isolator rated for a maximum load capacity of 44 pounds. This round rubber isolator is designed to absorb and dampen mechanical vibration and shock between mounted equipment and supporting structure. Measuring 1 inch in diameter and 3/4 inch in height, it uses a 5/16-18 threaded stud on both ends for straightforward bolted installation. HVAC technicians, mechanical contractors, and equipment installers use this type of isolator to reduce structure-borne noise and vibration transmission in equipment mounting applications.

This isolator is suited for residential and light commercial applications where vibration isolation is needed at equipment mounting points. Typical use cases include mounting small compressors, fans, blowers, pumps, and similar mechanical equipment to frames, brackets, or base rails. Its compact profile and standard 5/16-18 thread make it a practical fit for a wide range of equipment mounting configurations in HVAC and mechanical systems.

Key Features

• 44-pound maximum load capacity for light-duty equipment mounting
• 5/16-18 stud-to-stud thread configuration on both ends
• Compact round profile: 1 inch diameter, 3/4 inch height
• Absorbs mechanical vibration and reduces structure-borne noise transmission
• Single-unit packaging suitable for individual replacement or small-quantity jobs

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for light mechanical equipment requiring a 5/16-18 stud mount with a 44-pound load rating.

Installation Notes

Installation is performed by HVAC technicians or mechanical contractors as part of equipment mounting procedures. De-energize and lock out all equipment before beginning isolator installation or replacement. Thread the isolator studs into the equipment and mounting surface by hand first, then snug with appropriate hand tools - do not overtighten, as over-torquing can compress the isolator body and reduce its vibration-damping effectiveness. Verify that the total combined load across all isolators does not exceed the rated capacity per mount point.
