Tech Products 51161 Vibration Isolator 45 Lb 1/4-20

Product Description

The TECH PRODUCTS 51161 is a round, stud and plate mount vibration isolator rated for loads up to 45 pounds. It measures 1 inch in diameter and 0.75 inches high, with a 1/4-20 threaded stud and a 0.5-inch thread length. Designed to absorb and dampen mechanical vibration, this isolator mounts between equipment bases and supporting structures to reduce noise transmission and protect surrounding components. HVAC technicians, plumbers, and mechanical contractors install these on compressors, fans, pumps, and similar rotating or vibrating equipment where noise and vibration control are required.

This isolator is suited for light-duty commercial and residential applications. It installs anywhere a compact, low-profile mount is needed to isolate vibration between a piece of equipment and its mounting surface. Common applications include small air handlers, fan coil units, fractional horsepower motors, and pump assemblies. The 1/4-20 thread size is a common fastener standard, making this isolator straightforward to integrate into existing mounting hardware setups without custom fabrication.

Key Features

• 45-pound maximum load capacity per isolator
• 1/4-20 threaded stud and plate dual mount configuration
• Compact round profile at 1 inch in diameter and 0.75 inches high
• 0.5-inch thread length for secure fastener engagement
• Low-profile design suitable for space-constrained installations

Compatibility

Designed as an OEM-style replacement or new-install vibration isolator for light-duty HVAC, plumbing, and mechanical equipment requiring 1/4-20 stud and plate mounting up to 45 pounds per mount point.

Installation Notes

Installation is typically performed by a licensed HVAC technician or mechanical contractor. Power down or de-energize all associated equipment before mounting or replacing isolators. Ensure the combined isolator load rating meets or exceeds the total equipment weight when selecting the number of mount points. Follow applicable mechanical codes and equipment manufacturer guidelines for isolator placement and spacing.
