Tech Products 51553-4 Vibration Isolator 1260 Lb

Product Description

The TECH PRODUCTS 51553-4 is a plate-to-plate vibration isolator rated for a maximum load capacity of 1260 pounds. It features a 1/2-13 threaded connection and mounts between two flat plate surfaces to absorb and dampen mechanical vibration in HVAC and mechanical equipment installations. The unit measures 3.125 inches in diameter and 1.5 inches in height, making it a compact, purpose-built isolator for equipment bases, fan assemblies, compressors, and similar rotating or reciprocating machinery. Installation is performed by HVAC mechanics or millwrights as part of vibration isolation systems.

This isolator is suited for use in both commercial and residential mechanical systems where equipment vibration must be isolated from building structure or equipment frames. Typical applications include rooftop HVAC units, air handling units, pump bases, and fan coil supports. The plate-to-plate mount style allows for straightforward integration into equipment base rail assemblies and equipment pads where flat mounting surfaces are present on both the equipment and the support structure.

Key Features

• 1260 pound maximum load capacity for heavy-duty mechanical equipment support
• Plate-to-plate mount type for flat surface-to-surface installations
• 1/2-13 thread size for standard fastener compatibility
• Round profile at 3.125 inches diameter for compact footprint
• 1.5 inch overall height keeps equipment profiles low

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for plate-mount equipment bases requiring a 1/2-13 threaded, round plate-to-plate isolator with up to 1260 pounds of load capacity.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Power down and lock out all associated equipment before installing or replacing isolators on operating machinery. Ensure both mating plate surfaces are clean, flat, and free of debris before torquing fasteners. Consult local mechanical codes and equipment manufacturer documentation for proper isolator placement and load distribution requirements.
