Tech Products 51383 Vibration Isolator 210 Lb 3/8-16

Product Description

The TECH PRODUCTS 51383 is a round vibration isolator designed to reduce structure-borne noise and mechanical vibration transmitted between equipment and mounting surfaces. Rated for a maximum load capacity of 210 pounds, this isolator uses a stud-and-plate mount configuration with a 3/8-16 thread size, making it well suited for anchoring HVAC equipment, compressors, fans, pumps, and similar mechanical units. The overall diameter is 1.5 inches with a height of 1 inch and a thread length of 0.625 inches. Installation is straightforward and is typically handled by HVAC technicians, mechanical contractors, or equipment riggers during equipment startup or replacement service.

This isolator is commonly used in light commercial and residential mechanical applications where vibration attenuation is required at equipment mounting points. Typical install scenarios include rooftop HVAC units, air handlers, small compressors, and hydronic pump bases where controlling vibration transfer to the building structure is a priority. The stud and plate mount style allows flexible attachment in a variety of equipment base configurations.

Key Features

• Maximum load capacity of 210 pounds per isolator
• 3/8-16 thread size with 0.625-inch thread length for secure fastening
• Stud and plate dual-mount configuration for flexible installation
• Compact round profile - 1.5 inches in diameter and 1 inch in height
• Reduces structure-borne vibration and mechanical noise transmission
• Lightweight at 0.2 pounds for easy handling on the job

Compatibility

Designed as an OEM-style replacement or service install vibration isolator for mechanical equipment requiring a 3/8-16 stud or plate mount with up to 210 pounds of load capacity per mounting point.

Installation Notes

Installation should be performed by a qualified HVAC technician or mechanical contractor. De-energize and lock out all equipment before removing or installing mounting hardware. Ensure the isolator is installed plumb and that load is distributed evenly across all mounting points to achieve rated attenuation performance. Do not exceed the 210-pound rated load capacity per isolator.
