Gardner Spring GE0300-0551250S Extension Spring

Product Description

The GARDNER SPRING GE0300-0551250S is a close-wound extension spring designed to resist pulling forces and return components to their original position when load is released. It measures 0.3 inches in outside diameter with a wire diameter of 0.055 inches and a maximum extended length of 1.56 inches. The spring rate is 55.0077 pounds per inch, and initial tension is 1.6685 pounds, meaning it requires that load before it begins to extend. Sold in a package of 3 pieces, this spring suits tight-clearance assemblies across HVAC, plumbing, electrical, and general mechanical applications where a compact, light-duty tension element is needed.

This spring is appropriate for residential and light commercial equipment where a small-diameter, low-force extension spring is required. Typical applications include damper linkages, valve return mechanisms, panel latches, and control assemblies. The inside hook length of 1.25 inches allows for straightforward loop-to-post or loop-to-pin attachment without modification in most standard mounting configurations. Technicians working on HVAC equipment, appliances, or mechanical control panels will find this spring a practical direct replacement or repair component.

Key Features

• Spring rate of 55.0077 pounds per inch for consistent, predictable return force
• Initial tension of 1.6685 pounds holds coils closed until the working load is applied
• Outside diameter of 0.3 inches fits tight-clearance mounting locations
• Wire diameter of 0.055 inches provides a balance of flexibility and durability
• Inside hook length of 1.25 inches accommodates standard pin and post attachments
• Packaged in quantities of 3 pieces per pack

Compatibility

Designed as a direct-fitment extension spring for mechanical assemblies requiring a 0.3 inch OD, 0.055 inch wire diameter, and 1.56 inch maximum extended length. Verify spring rate and initial tension requirements against the original equipment specification before installation.

Installation Notes

Installation should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. De-energize or isolate the equipment and relieve any stored mechanical tension before removing or installing springs. Use appropriate needle-nose pliers or spring hooks to seat the loops onto mounting pins without overstretching the spring beyond its rated extended length. Do not stretch the spring beyond the maximum extended length of 1.56 inches, as permanent deformation will compromise spring rate and service life.
