Gardner Spring V25C Extension Spring 9.42 Lb 0.38 in Od

Product Description

The GARDNER SPRING V25C is a galvanized steel extension spring engineered for reliable tensile force in light-to-medium duty mechanical assemblies. With an outside diameter of 0.38 inches and a wire diameter of 0.0475 inches, the spring delivers a rate of 1.78 lb/in with a maximum work load of 9.42 pounds. The free length is 6 inches, extending to a maximum of 10.05 inches under load. An initial tension of 1.50 pounds provides resistance to extension before the spring begins to deflect. The zinc-plated galvanized finish adds corrosion resistance, making this spring suitable for both indoor and light outdoor applications. HVAC technicians, millwrights, and general mechanical tradespeople commonly use extension springs of this profile in damper linkages, panel latches, and return mechanisms.

This extension spring is suited for residential and light commercial applications where a compact, small-diameter tensile spring is required. Typical use cases include HVAC damper return assemblies, door and panel latch mechanisms, and general mechanical tensioning applications. Each package contains 6 pieces, making it practical to keep spares on hand for service calls or production line use.

Key Features

• 0.38 inch outside diameter with 0.0475 inch wire diameter for compact fit in tight assemblies
• 1.78 lb/in spring rate provides predictable, linear extension force
• Maximum work load of 9.42 pounds with a maximum extended length of 10.05 inches
• 1.50 pound initial tension resists unwanted extension under no-load conditions
• Galvanized and zinc-plated steel construction for corrosion resistance
• Packaged in quantities of 6 for efficient stocking and service use

Compatibility

Designed as a direct-replacement or general-purpose extension spring for mechanical assemblies requiring a 0.38 inch OD, 6 inch free-length tensile spring with a 1.78 lb/in rate.

Installation Notes

Extension springs should be installed by a qualified mechanic or technician familiar with spring-loaded assemblies. Always de-energize or relieve tension from the surrounding mechanism before removing or installing springs to prevent snap-back injury. Use appropriate hook or loop attachment tools to seat the spring ends without overextending the spring beyond its maximum extended length of 10.05 inches. Inspect hooks or attachment points for wear before installation to ensure secure retention.
