The VALUE COLLECTION 03308814 is a stainless steel compression spring designed for use in mechanical assemblies, industrial equipment, and trade applications requiring consistent return force. The spring measures 0.72 inches outside diameter with a 1 inch free length and a wire diameter of 0.054 inches. It delivers a spring rate of 12.59 lb/in and handles a maximum work load of 8.34 pounds. The stainless steel construction resists corrosion in wet, chemical, or outdoor environments. This spring is sized to fit a 0.75 inch hole diameter and reaches a solid height of 0.255 inches under full compression. Mechanical technicians, HVAC service pros, and maintenance trades use this type of spring in valve assemblies, latches, damper mechanisms, and general control components.
This compression spring suits residential and light commercial applications where a compact, corrosion-resistant return spring is needed. Common install scenarios include HVAC damper linkages, plumbing valve internals, electrical enclosure latches, and general industrial maintenance. The 1 inch free length and 0.72 inch OD make it a practical fit for tight-clearance assemblies. Springs of this specification are also stocked as shop inventory by mechanical contractors for fast field replacement of worn or broken return springs in control systems and mechanical actuators.
Designed as a general-purpose OEM-style replacement compression spring for mechanical assemblies requiring a 0.72 inch OD, 1 inch free length, and 12.59 lb/in spring rate.
Installation should be performed by a qualified mechanical or trade technician. Before replacing a compression spring in any assembly, de-energize electrical components and relieve any system pressure per standard lockout/tagout procedures. Use appropriate hand tools and eye protection when handling compressed springs during installation or removal. Verify that the replacement spring matches the original free length, wire diameter, and spring rate before finalizing the assembly.
