Gardner Spring V31C Extension Spring 0.18 in Od 2.54 Lb

Product Description

The GARDNER SPRING V31C is a small-diameter steel extension spring designed for light-duty tensioning applications across mechanical, HVAC, and equipment assembly work. With an outside diameter of 0.18 inches and a wire diameter of 0.023 inches, this spring operates within a compact profile while delivering a maximum work load of 2.54 pounds and a spring rate of 0.42 lb/in. The overall free length is 6 inches, extending to a maximum of 10.75 inches under load. A galvanized, zinc-plated finish provides corrosion resistance for both indoor and light outdoor service environments. Sold in a package of 6 pieces.

The V31C suits applications requiring consistent, measured tension over a moderate extension range. Typical use cases include HVAC damper linkages, control panel latching mechanisms, light equipment enclosures, and general mechanical assemblies where a low-force, small-diameter extension spring is specified. The zinc-plated steel construction holds up in environments with incidental moisture exposure. This spring is appropriate for both OEM equipment assembly and field service replacement work performed by HVAC technicians, millwrights, and equipment mechanics.

Installation Notes

Extension springs should be installed and removed by qualified technicians familiar with stored-energy hazards. Always de-energize or depressurize the associated equipment before servicing spring-loaded assemblies. Use appropriate hooks or tooling to seat the spring ends securely and avoid overstretching beyond the rated maximum extended length of 10.75 inches, which can permanently set or damage the spring.
