Tech Products 51553-1 Vibration Isolator 450 Lb

Product Description

The TECH PRODUCTS 51553-1 is a plate-to-plate vibration isolator rated for 450 pounds of load capacity. It mounts between two flat surfaces to absorb and dampen mechanical vibration, reducing noise transmission and protecting equipment from vibration-induced wear. With an overall diameter of 3-1/8 inches and a height of 1-1/2 inches, this isolator uses a 1/2-13 thread configuration. It is a standard trade component installed by HVAC technicians, mechanical contractors, and equipment installers in commercial and industrial settings where vibration control is required.

This isolator is suited for use under HVAC equipment, compressors, pumps, fans, and other mechanical units mounted on flat structural surfaces. The plate-to-plate mount style makes it appropriate for base-mounted applications where both the equipment base and the mounting surface are flat. It is commonly specified in mechanical rooms, rooftop installations, and equipment pads where vibration isolation is part of the system design.

Key Features

• 450 pound load capacity for heavy mechanical equipment support
• Plate-to-plate mount type for flat surface-to-surface installations
• 1/2-13 thread size for secure fastening
• 3-1/8 inch overall diameter provides stable footprint
• 1-1/2 inch installed height for compact clearance requirements
• Lightweight at 0.5 pounds for easy handling during installation

Compatibility

Designed as a standard plate-to-plate vibration isolator for use with base-mounted HVAC equipment, pumps, compressors, and fans requiring a 1/2-13 threaded mount and flat surface mounting on both sides.

Installation Notes

Installation is typically performed by licensed HVAC technicians or mechanical contractors as part of equipment commissioning. Power down and de-energize all equipment before positioning isolators. Ensure both mounting surfaces are flat and clean before seating the isolator to achieve rated load distribution. Verify that fastener torque and equipment weight are within the 450 pound rated capacity before returning the system to service.
