Tech Products 51551-5 Vibration Isolator 1815 Lb

Product Description

The TECH PRODUCTS 51551-5 is a plate/stud vibration isolator rated for loads up to 1815 pounds. It is designed to absorb and dampen mechanical vibration between equipment bases and mounting surfaces, reducing noise transmission and structural stress in HVAC and mechanical systems. The isolator features a 1/2-13 threaded stud for secure attachment and measures 3.125 inches in diameter and 1.5 inches in height. It is a compact, heavy-duty isolation component suited for commercial and industrial equipment installations where vibration control is critical to system performance and longevity.

This isolator is used in HVAC, mechanical, and industrial applications where rotating or reciprocating equipment must be isolated from building structure or equipment frames. Typical installations include rooftop units, air handlers, compressors, pumps, and fans mounted on equipment pads or housekeeping pads. The plate and stud configuration allows for straightforward bolted connections to both the equipment base and the mounting surface, making it a practical choice for mechanical contractors working with vibration-sensitive installations.

Key Features

• 1815-pound load capacity suitable for heavy commercial and industrial equipment
• Plate/stud isolator type provides secure, bolted connection at both mounting points
• 1/2-13 threaded stud for standard hardware compatibility
• 3.125-inch overall diameter in a low-profile 1.5-inch height
• Compact form factor allows installation in space-constrained equipment bases

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for commercial and industrial HVAC and mechanical equipment requiring a plate/stud mount with a 1/2-13 thread size.

Installation Notes

Installation is typically performed by licensed mechanical or HVAC contractors. De-energize and lock out all equipment before beginning isolator installation or replacement. Ensure the mounting surface is level and structurally sound before torquing fasteners. Verify the combined equipment weight does not exceed the isolator load rating when determining the number of isolators required per unit.
