With an outside diameter of 0.312 inches and a wire diameter of 0.0286 inches, this spring delivers a spring rate of 0.55 pounds per inch and a maximum work load of 2.77 pounds. The free length is 2.5 inches, extending to a maximum of 6.77 inches under load. It is suitable for light-duty mechanical assemblies across HVAC equipment, plumbing hardware, and general industrial applications. Licensed technicians and maintenance professionals working on equipment with tensioning mechanisms will find this a dependable OEM-style replacement component.\u003c\/p\u003e\u003cp\u003eThis extension spring fits applications requiring a compact, low-load tensioning element. Common uses include damper linkages, door closure mechanisms, valve actuator returns, and small equipment latching systems found in residential and light commercial service environments. The spring ships in a package quantity of six, making it practical for service shops and technicians who replace these components routinely across multiple units.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.312 inch outside diameter suits tight-clearance mechanical assemblies\u003c\/li\u003e\n\u003cli\u003e0.55 lb\/in spring rate provides consistent, predictable return force\u003c\/li\u003e\n\u003cli\u003e2.77 lb maximum work load rated for light-duty tensioning applications\u003c\/li\u003e\n\u003cli\u003eExtends from 2.5 inches free length to 6.77 inches maximum extended length\u003c\/li\u003e\n\u003cli\u003e0.0286 inch wire diameter for precision load control\u003c\/li\u003e\n\u003cli\u003eSold in a package of 6 for multi-unit service efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement extension spring for light-duty mechanical assemblies in HVAC, plumbing, and general industrial equipment requiring a 0.312 inch OD spring with a 0.55 lb\/in spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with spring-loaded mechanical assemblies. Always de-energize or depressurize the equipment before replacing any spring components to prevent injury from sudden release of stored energy. Inspect mounting hooks or attachment points for wear or deformation before installing the new spring. Do not stretch the spring beyond the rated maximum extended length of 6.77 inches during installation or operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0286 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 6.77 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.55 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 2.77 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6 pieces\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GARDNER SPRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: E20C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51998943445298,"sku":"E20C-SS","price":17.35,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f5d5bbd0cb4c172042ac3af3109a1e2_c035f88b-6852-45d2-9a9b-a28a0b9908d9.jpg?v=1789995212","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e20c-ss-extension-spring-0-312in-od-2-77lb","provider":"Voomi Supply","version":"1.0","type":"link"}
