Gardner Spring 36143G Compression Spring 0.407in Od 2.75in

Product Description

The GARDNER SPRING 36143G is a utility-grade compression spring designed for general mechanical and industrial applications. It features a 0.407-inch outside diameter and a free length of 2.75 inches, with a wire diameter of 0.054 inches and a spring rate of 12.17 pounds per inch. Constructed from steel with a zinc finish, this spring delivers consistent compression force across a wide range of load requirements. The closed end type provides stable seating during operation. HVAC technicians, plumbers, and mechanical trades commonly encounter this spring format in dampers, valves, and equipment assemblies.

This compression spring suits residential and light commercial applications where a compact, consistent-rate steel spring is required. Typical install scenarios include damper actuators, valve assemblies, pump mechanisms, and various equipment where a controlled return or resistance force is needed. The zinc finish provides basic corrosion resistance for use in dry or mildly humid environments. Parts are sold in quantities of 10 per package, making this SKU practical for service stock or bench inventory.

Compatibility

Designed as an OEM-style replacement or service stock compression spring for mechanical assemblies requiring a closed-end utility spring with a 0.407-inch outside diameter and 2.75-inch free length.

Installation Notes

Installation should be performed by a qualified technician familiar with the mechanical assembly being serviced. Power down or de-energize any equipment before replacing internal springs, and relieve all system pressure before disassembling valves or actuators. Confirm the spring pocket diameter, free length, and spring rate match the application requirements before installation. Avoid overcompressing the spring beyond its solid height of 1.36 inches during assembly.
