Gardner Spring GE0300-037-1370 Extension Spring 0.3in Od

Product Description

The GARDNER SPRING GE0300-037-1370 is a small-format extension spring designed for applications requiring controlled linear tension over a defined travel range. With an outside diameter of 0.3 inches, an extended length of 2.37 inches, and a wire diameter of 0.037 inches, this spring delivers a rated spring rate of 6.6 pounds per inch. An initial tension of 0.65 pounds keeps coils closed at rest, which reduces unwanted movement before the load is applied. It is used in light-duty mechanical assemblies, HVAC actuators, linkage returns, and similar trade applications where compact geometry and repeatable force are required.

This extension spring fits light-duty residential and commercial mechanical assemblies where a small-diameter, low-mass return or tension element is needed. Typical install scenarios include control linkage returns, damper actuator assemblies, panel latches, and similar mechanisms found in HVAC equipment, plumbing fixtures, and electrical enclosures. The package includes 3 pieces, making it practical for service calls where a spare is advisable.

Key Features

• Outside diameter of 0.3 inches for compact fitment in tight assemblies
• Extended length of 2.37 inches provides defined travel range
• Wire diameter of 0.037 inches suited for light-duty tension loads
• Spring rate of 6.6 pounds per inch delivers consistent, predictable force
• Initial tension of 0.65 pounds keeps coils seated before load is applied
• Packaged in quantity of 3 to support field service needs

Compatibility

Designed as a light-duty extension spring for use in residential and commercial mechanical assemblies requiring a 0.3-inch OD form factor with a 6.6 pound-per-inch spring rate.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or mechanical contractors during equipment service or actuator linkage repair. Ensure the mating attachment points match the spring hook style and that the assembly is de-energized or shut off before replacing any spring component. Avoid stretching the spring beyond its rated extended length, as permanent deformation will affect force output and service life.
