Gardner Spring 37038GS Extension Spring 0.25 in Od

Product Description

The GARDNER SPRING 37038GS is a stainless steel extension spring designed for light-duty tensioning applications across HVAC, plumbing, electrical, and general mechanical systems. It features a 0.25 inch outside diameter, a 0.026 inch wire diameter, and a free length of 2 inches. The spring rate is 0.87 pounds per inch, with an initial tension of 0.40 pounds and a maximum work load of 2.70 pounds. When fully extended, the spring reaches 4.64 inches. The plain finish on the stainless steel construction provides resistance to corrosion in wet or humid environments. This spring is suitable for installation by HVAC technicians, plumbers, and electricians working with light mechanical assemblies.

This extension spring is appropriate for residential and light commercial applications where a small-diameter, low-load tensioning component is required. Typical uses include control linkages, damper assemblies, access panel latches, and other mechanical return mechanisms found in HVAC equipment, electrical enclosures, and plumbing assemblies. Each package contains 3 pieces, allowing for on-hand replacements during service calls. The compact free length of 2 inches makes it suitable for confined mounting spaces common in trade equipment.

Installation Notes

Extension springs should be installed by a qualified technician familiar with the mechanical assembly being serviced. Power down or de-energize any equipment before accessing spring-loaded components. Use appropriate spring hooks or pliers to seat the spring without overstretching beyond the maximum extended length of 4.64 inches, as exceeding this limit can permanently deform the spring. Refer to the equipment manufacturer's service documentation for correct spring placement and attachment points.
