Tech Products 51550-2 Vibration Isolator 540 Lb M12

Product Description

The TECH PRODUCTS 51550-2 is a plate-to-plate vibration isolator rated for loads up to 540 pounds. It is designed to absorb and dampen mechanical vibration between two bolted surfaces, reducing structure-borne noise and protecting connected equipment. The isolator uses an M12 thread size and measures approximately 79 millimeters in diameter and 38 millimeters in height. It is commonly installed by HVAC technicians, mechanical contractors, and industrial maintenance professionals in applications where vibration isolation between rigid mounting plates is required.

This isolator is suited for residential and commercial mechanical systems where vibrating equipment must be isolated from supporting structures. Typical applications include HVAC equipment mounting, compressor bases, fan assemblies, pump installations, and other mechanical machinery that generates sustained vibration. Its plate-to-plate design makes it a straightforward fit in bolted sandwich-mount configurations where both the top and bottom faces contact rigid plates.

Key Features

• 540-pound load capacity for heavy mechanical equipment support
• M12 thread size for standard metric bolt compatibility
• Plate-to-plate isolator design for sandwich-mount installations
• 79 millimeter overall diameter provides stable footprint
• 38 millimeter installed height suits low-clearance mounting scenarios
• Reduces structure-borne vibration and associated noise transmission

Compatibility

Designed as an OEM-style replacement or new-installation vibration isolator for mechanical equipment mounting applications requiring an M12 plate-to-plate isolator with a 540-pound load rating.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Equipment must be fully de-energized and safely supported before removing or installing isolators. Follow the equipment manufacturer's torque guidelines for M12 fasteners and verify that the total static load does not exceed the 540-pound rated capacity of the isolator. Consult applicable mechanical codes for vibration isolation requirements in your jurisdiction.
