Tech Products 51142 Vibration Isolator 50 Lb 1/4-20 Stud

Product Description

The TECH PRODUCTS 51142 is a stud-to-stud vibration isolator designed to absorb and dampen mechanical vibration in HVAC, refrigeration, and light industrial equipment. It handles a maximum load capacity of 50 pounds and uses a 1/4-20 threaded stud mount on both ends. The isolator measures 1 inch in diameter and 0.75 inches in height, making it a compact solution for tight equipment bays and mounting brackets. With a thread length of 0.5 inches, it provides adequate engagement for secure fastening. HVAC technicians and mechanical contractors install this type of isolator to reduce vibration transmission from compressors, fan assemblies, and air handlers to the surrounding structure.

This isolator is suited for residential and light commercial HVAC applications where vibration control is required at equipment mounting points. Typical installations include compressor mounts, condenser fan motor brackets, and air handler bases. Its round profile and stud-through design make it a straightforward drop-in replacement in applications calling for 1/4-20 stud-mount isolators with a 50-pound load rating. The compact form factor fits in space-constrained mounting locations common in packaged rooftop units and split-system equipment.

Key Features

• 50-pound maximum load capacity suitable for compressors, fan motors, and light mechanical equipment
• 1/4-20 stud-to-stud mount on both ends for direct bolt-in installation
• 1 inch overall diameter with 0.75 inch height for use in tight mounting clearances
• 0.5 inch thread length provides solid fastener engagement
• Round profile for consistent vibration dampening across the contact surface

Compatibility

Designed as an OEM-style replacement vibration isolator for residential and light commercial HVAC and refrigeration equipment using 1/4-20 stud-mount isolators with a 50-pound load rating.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified mechanical contractors. Power down and lock out the equipment before removing or replacing isolators. Verify thread engagement on both studs before applying load. Do not exceed the rated 50-pound load capacity, as overloading can cause premature failure and allow metal-to-metal contact that defeats vibration isolation.
