Gardner Spring 37041GS Extension Spring 0.25in Od

Product Description

The GARDNER SPRING 37041GS is a small-diameter extension spring manufactured from stainless steel with a plain finish. It is designed to store and release tensile energy when stretched, returning to its free length once load is removed. With an outside diameter of 0.25 inches, a wire diameter of 0.031 inches, and a free length of 2.5 inches, this spring is suited for compact mechanism applications. The spring rate is 1.74 pounds per inch, the initial tension is 0.70 pounds, and the maximum work load is 4.52 pounds at a maximum extended length of 4.7 inches. Mechanical technicians, HVAC service techs, and equipment repair professionals commonly install this type of spring.

This extension spring is appropriate for use in light-duty mechanical assemblies where a small, corrosion-resistant tensile spring is required. Typical applications include HVAC damper linkages, control panel latches, appliance mechanisms, and general-purpose industrial equipment. The stainless steel construction makes it suitable for environments with moderate moisture exposure. This part is sold in a package quantity of three, making it practical for service kits or bench stock.

Key Features

• Stainless steel construction with plain finish for corrosion resistance
• Spring rate of 1.74 pounds per inch for predictable load-deflection behavior
• Maximum work load of 4.52 pounds with a maximum extended length of 4.7 inches
• Initial tension of 0.70 pounds holds the spring closed under zero applied load
• Compact 0.25 inch outside diameter fits tight clearance assemblies
• Sold in a package of 3 pieces for service stock convenience

Compatibility

Designed as a general-purpose replacement extension spring for light-duty mechanical and HVAC equipment applications requiring a 0.25 inch OD, 2.5 inch free length stainless steel spring with a 1.74 pounds per inch spring rate.

Installation Notes

Installation should be performed by a qualified technician familiar with mechanical spring assemblies. De-energize and lock out any equipment before replacing springs to prevent injury from unexpected mechanism movement. Use appropriate pliers or spring hooks to seat the end loops without overstretching the spring beyond its maximum extended length of 4.7 inches. Overstretching a spring past its rated maximum load will permanently deform the coils and compromise performance.
