Gardner Spring V4C-SS Extension Spring 26.4 Lb 0.64 in Od

Product Description

The GARDNER SPRING V4C-SS is a stainless steel extension spring designed for applications requiring controlled tensile resistance. With an outside diameter of 0.64 inches and a wire diameter of 0.08 inches, this spring delivers a spring rate of 8.45 lb/in and a maximum work load of 26.4 lb. The overall free length is 4.0 inches, and the maximum extended length reaches 6.38 inches. Initial tension is rated at 3.7 lb, meaning the spring resists opening until that threshold is exceeded. Sold in a package of 3 pieces, this part is suited for mechanical assemblies, industrial equipment, and trade applications where a compact, corrosion-resistant extension spring is required.

This extension spring is appropriate for residential and light commercial mechanical systems where tensile spring force is needed. Typical install scenarios include HVAC damper linkages, panel latches, door assemblies, and general mechanical tension applications. The stainless steel construction makes it a suitable choice in environments with moisture exposure or where corrosion resistance is a priority. The plain finish requires no additional surface treatment before installation.

Key Features

• Stainless steel construction provides corrosion resistance in humid or wet environments
• Spring rate of 8.45 lb/in for predictable, linear tensile force output
• Maximum work load of 26.4 lb suits a range of light-duty mechanical tension applications
• Initial tension of 3.7 lb keeps the spring closed until threshold force is applied
• Compact 0.64 inch outside diameter fits tight mechanical clearances
• Packaged in a quantity of 3 pieces per package

Compatibility

Designed as a standard-profile extension spring suitable for mechanical assemblies requiring a 0.64 inch OD, 4.0 inch free length, and 8.45 lb/in spring rate in a stainless steel construction.

Installation Notes

Installation is typically performed by mechanical technicians or HVAC service professionals. De-energize and lock out any associated equipment before removing or installing tension springs to prevent unexpected release of stored energy. Use appropriate pliers or spring hooks rated for the load; never overstretch the spring beyond its maximum extended length of 6.38 inches, as this will permanently deform the coils. Verify hook orientation and attachment point clearance before returning the assembly to service.
