Tech Products 51390 Vibration Isolator 95 Lb Stud Stud

Product Description

The TECH PRODUCTS 51390 is a stud-to-stud vibration isolator rated for 95 pounds of load capacity. It is designed to dampen mechanical vibration and reduce structure-borne noise in HVAC and mechanical systems. The isolator features a 3/8-16 threaded stud on each end and measures 1.5 inches in diameter and 1 inch in height. HVAC technicians and mechanical contractors install these isolators between equipment mounting points and structural surfaces to limit vibration transmission to the building structure. The compact form factor suits tight equipment bases and equipment pads where clearance is limited.

This vibration isolator is suited for residential and light commercial HVAC applications including condensing units, air handlers, compressors, fans, and other rotating equipment that generates vibration during operation. It mounts inline between equipment studs and mounting surfaces, absorbing vibration at the source rather than allowing it to travel through the frame or slab. The 3/8-16 thread size is common on standard equipment mounting hardware.

Key Features

• 95 pound load capacity per isolator for reliable vibration control under equipment weight
• 3/8-16 stud-to-stud configuration compatible with standard equipment mounting hardware
• 1.5 inch overall diameter in a compact 1 inch height for installations with limited clearance
• Reduces structure-borne noise and vibration transmission from rotating mechanical equipment
• Sold individually for flexible quantity purchasing based on job requirements

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for HVAC condensing units, air handlers, fans, and other mechanical equipment using 3/8-16 threaded mounting studs with a load rating at or below 95 pounds per mount point.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. De-energize and lock out the equipment before servicing any mounting points. Thread the isolator onto the equipment stud and the mounting surface stud by hand before final tightening to avoid cross-threading. Verify that the total combined load across all isolators does not exceed each unit's rated capacity before returning equipment to service.
