Tech Products 51553-2 Vibration Isolator 660 Lb

Product Description

The TECH PRODUCTS 51553-2 is a plate-to-plate vibration isolator rated for up to 660 pounds of load capacity. It measures 3-1/8 inches in diameter and 1-1/2 inches in height, with a 1/2-13 threaded mounting configuration. This isolator is designed to absorb and dampen mechanical vibration between equipment bases and mounting surfaces, reducing noise transmission and protecting structural connections. It is commonly installed by HVAC technicians, mechanical contractors, and equipment installers who need a reliable isolation solution beneath compressors, air handlers, pumps, or other vibrating mechanical equipment.

This vibration isolator is suited for both commercial and residential mechanical installations where equipment vibration must be isolated from the building structure or mounting pad. The plate-to-plate design sandwiches the isolating element between two flat mounting surfaces, making it appropriate for equipment pads, rooftop units, inline pumps, and similar applications. Its compact profile allows installation in tight mounting configurations without significant height addition to the equipment footprint.

Key Features

• 660-pound load capacity for heavy mechanical equipment support
• Plate-to-plate isolator design provides stable, flat-surface mounting on both sides
• 1/2-13 thread size for standard hardware compatibility
• 3-1/8 inch overall diameter in a low-profile 1-1/2 inch height package
• Lightweight at 0.5 pounds for easy handling during installation

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for mechanical equipment requiring plate-to-plate mounting with a 1/2-13 thread and up to 660 pounds of load capacity.

Installation Notes

Installation is typically performed by HVAC technicians or mechanical contractors as part of equipment mounting or replacement service. De-energize and lock out all equipment before beginning isolator installation or removal. Verify that the mounting surface is clean, flat, and capable of supporting the rated load before securing the isolator. Follow all applicable mechanical codes and equipment manufacturer mounting specifications when determining isolator placement and fastener torque.
