Tech Products 51392 Vibration Isolator 185 Lb Stud Mount

Product Description

The TECH PRODUCTS 51392 is a stud-to-stud vibration isolator rated for 185 pounds of load capacity. It is designed to dampen mechanical vibration and reduce noise transfer between equipment and mounting surfaces in HVAC, refrigeration, and mechanical system installations. The isolator features a 3/8-16 threaded stud configuration on both ends and measures 1.5 inches in diameter and 1 inch in height. HVAC technicians and mechanical contractors install this type of isolator under compressors, fan assemblies, condensing units, and similar vibration-generating equipment to protect structures and extend equipment life.

This vibration isolator is suited for residential and light commercial applications where equipment vibration must be managed at the point of mounting. It is commonly used beneath rooftop units, indoor air handlers, compressors, and other mechanical equipment that transmits vibration through mounting hardware or structural surfaces. The stud-to-stud design allows for inline installation between the equipment base and a fixed mounting point, providing a clean, load-bearing anti-vibration connection without brackets or additional hardware.

Key Features

• 185-pound load capacity for reliable vibration isolation under heavy equipment
• 3/8-16 threaded stud on both ends for straightforward inline mounting
• 1.5-inch overall diameter fits standard equipment mounting footprints
• 1-inch overall height keeps equipment close to the mounting surface
• Compact form factor suits tight installation spaces in mechanical rooms and rooftop applications

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for HVAC compressors, fan assemblies, and mechanical equipment using 3/8-16 stud mounting configurations.

Installation Notes

This isolator is installed by HVAC technicians and mechanical contractors as part of equipment mounting procedures. Always de-energize and lock out equipment before servicing mounting hardware. Thread both studs fully into the equipment base and mounting surface, ensuring the isolator is loaded vertically within its rated capacity. Do not exceed the 185-pound load rating, and verify all fasteners are secure before returning equipment to service.
