Gardner Spring E38C-SS Extension Spring 0.375in Od Stainless

Product Description

The GARDNER SPRING E38C-SS is a stainless steel extension spring designed for light-duty tensioning and return-force applications across HVAC, mechanical, and general trade assemblies. It features a 0.375-inch outside diameter, a wire diameter of 0.0475 inches, and a spring rate of 6.97 lb/in. The cross-over end style provides a secure hook-to-hook connection in confined mounting arrangements. At a maximum work load of 10.03 lb and a maximum extended length of 3.1 inches, this spring delivers predictable, repeatable force output. The plain stainless steel finish resists corrosion in damp or outdoor service environments.

This spring suits residential and light commercial applications where a compact, corrosion-resistant tension element is required. Common install scenarios include HVAC damper return assemblies, access panel latches, valve linkages, and general mechanical tensioning points. The cross-over end configuration allows straightforward attachment to hooks, pins, or anchor posts without secondary hardware. It is sold in a package quantity of three units, making it practical for service trucks and parts-room stocking.

Installation Notes

Installation is typically performed by HVAC technicians, mechanical contractors, or maintenance trades. Shut down and de-energize any associated equipment before removing or installing tension springs to prevent unexpected movement of linked components. Use appropriate hand tools to seat the cross-over ends fully on their anchor points before restoring load. Verify the installed free length and extended length against the assembly specification before returning the system to service.
