Tech Products 51551-1 Vibration Isolator 360 Lb Plate Stud

Product Description

The TECH PRODUCTS 51551-1 is a plate/stud vibration isolator rated for 360 pounds of load capacity. It measures 3.125 inches in diameter and 1.5 inches in height, with a 1/2-13 threaded stud connection. This isolator is designed to absorb and dampen mechanical vibration between equipment and its mounting surface, reducing noise transmission and protecting structural connections. HVAC technicians, mechanical contractors, and equipment installers commonly use this type of isolator when mounting compressors, air handlers, pumps, and other vibrating mechanical equipment to curbs, bases, or structural supports.

This isolator suits residential and light commercial HVAC and mechanical applications where equipment vibration must be isolated from a building structure or mounting pad. The plate/stud configuration allows it to be sandwiched between a mounting plate and a structural surface, with the threaded stud securing the assembly. It is suited for installations where a compact, low-profile isolator is required and the load per mounting point falls within the 360-pound rating.

Key Features

• 360-pound load capacity per isolator for effective vibration control at each mounting point
• Plate/stud design allows secure sandwiched mounting between equipment base and support surface
• 1/2-13 threaded stud provides standard compatibility with common mechanical fasteners
• 3.125-inch overall diameter provides a stable footprint in a compact form factor
• Low-profile 1.5-inch height suits tight clearance installations
• Lightweight at 0.5 pounds, minimizing added load to the mounting assembly

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for HVAC equipment, pumps, compressors, and mechanical units requiring a 1/2-13 plate/stud mount with up to 360 pounds of load capacity per point.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors. De-energize and lock out all equipment before installing or replacing isolators. Verify that the total equipment weight is distributed evenly across all mounting points so no single isolator exceeds its rated capacity. Follow equipment manufacturer mounting instructions and applicable mechanical codes for proper isolator placement and fastener torque procedures.
