Gardner Spring 37009GS Extension Spring 3/32 in Od

Product Description

The GARDNER SPRING 37009GS is a small-diameter extension spring manufactured from stainless steel and suited for precision light-load applications. With an outside diameter of 0.0938 inches (3/32 inch nominal) and a wire diameter of 0.0100 inches, this spring delivers a spring rate of 1.04 lb/in with a maximum work load of 0.52 lb. The free length is 0.375 inches (3/8 inch), and the maximum extended length is 0.83 inches. The plain finish stainless steel construction provides corrosion resistance in demanding service environments. This part ships in a pack of 3 pieces, making it practical for bench stock or small repair quantities.

This extension spring is appropriate for light mechanical assemblies, control linkages, and instrument-level tensioning applications common in HVAC controls, electrical enclosures, and small equipment mechanisms. Its compact geometry suits installations where space is constrained and low-force return tension is required. Technicians working on damper actuators, relay mechanisms, or similar small-component assemblies will find this spring a direct fit for light-duty extension tasks. The stainless steel material makes it a dependable choice in environments exposed to moisture or mild chemical exposure.

Installation Notes

Installation of small extension springs in control or mechanical assemblies should be performed by qualified technicians familiar with the host equipment. Always de-energize and lock out the equipment before accessing spring mechanisms. Use appropriate small-tool fixtures to seat hook ends without overstretching the spring beyond its maximum extended length, as exceeding rated extension can permanently deform the coil. Follow the equipment manufacturer's service documentation for correct hook orientation and attachment points.
