Gardner Spring E37C-SS Extension Spring 0.375 in Od Stainless

Product Description

The GARDNER SPRING E37C-SS is a stainless steel extension spring designed for light-duty mechanical applications requiring consistent tensile force across a defined travel range. With a 0.375 inch outside diameter and a wire diameter of 0.0475 inches, this spring handles a maximum work load of 10.03 pounds at a maximum extended length of 2.66 inches. The spring rate is 8.43 pounds per inch, providing predictable linear resistance throughout its travel. Cross-over end style allows for secure loop attachment in tight assemblies. At 1.75 inches overall length in the free state, this is a compact spring suited for confined mounting locations. Typically installed by HVAC technicians, equipment assemblers, and mechanical maintenance professionals.

This extension spring is suited for residential and commercial mechanical assemblies where corrosion resistance and reliable load characteristics are required. Common applications include HVAC equipment linkages, damper return mechanisms, light-duty panel latches, and general equipment assemblies that operate in humid or washdown environments where stainless steel construction is preferred over carbon steel alternatives. The cross-over end style simplifies hook engagement during installation and reduces side loading on the attachment points.

• Sold in a package quantity of 3 pieces per pack

Compatibility

Designed as an OEM-style replacement or service stock extension spring for light-duty mechanical assemblies requiring a 0.375 inch OD cross-over end spring in stainless steel.

Installation Notes

Extension springs should be installed and removed with appropriate spring hooks or pliers to prevent overextension beyond the maximum extended length of 2.66 inches, which can permanently deform or fatigue the coils. De-energize or mechanically lock any system under load before removing a spring from service. Wear eye protection when handling loaded springs, as unexpected release can cause injury. Verify the attachment points are clean and free of burrs before seating the cross-over ends.
