It has an outside diameter of 0.5 inches, a wire diameter of 0.0625 inches, and an overall free length of 8 inches. Under load, it extends to a maximum of 12.95 inches. The spring rate is 2.05 lb\/in, with an initial tension of 4.6 lb and a maximum work load of 18.67 lb. The zinc-plated, galvanized finish provides corrosion resistance in typical indoor service environments. Sold in a package of 3 pieces.\u003c\/p\u003e\n\u003cp\u003eThis extension spring is suited for residential and light commercial equipment where a small-diameter, moderate-load tension spring is required. Common applications include door assemblies, damper linkages, equipment latches, and mechanical return mechanisms found in HVAC systems, appliances, and general trade equipment. It is installed wherever a controlled return force or tension load is needed along a linear axis.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGalvanized and zinc-plated finish for corrosion resistance in indoor environments\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 2.05 lb\/in for predictable, linear load response\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 18.67 lb with an initial tension of 4.6 lb\u003c\/li\u003e\n  \u003cli\u003eExtends from 8 inches free length to 12.95 inches maximum extended length\u003c\/li\u003e\n  \u003cli\u003eWire diameter of 0.0625 inches with 0.5 inches outside diameter\u003c\/li\u003e\n  \u003cli\u003eSold in a pack of 3 pieces, suitable for stocking or multi-unit service calls\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement extension spring for mechanical assemblies requiring a 0.5 inches OD, 8 inches free-length tension spring with an 18.67 lb maximum work load rating.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eExtension springs should be installed by qualified mechanical or HVAC technicians familiar with tension-spring applications. Always de-energize and relieve any stored mechanical tension in the assembly before removing the existing spring. Use appropriate spring hooks or installation tools to seat the spring ends without overstretching beyond the 12.95 inches maximum extended length. Exceeding the maximum extended length can permanently deform the spring and reduce service life.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Free Length\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 12.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 2.05 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 4.6 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 18.67 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Galvanized, Zinc-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.42 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: V40C\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52082151784754,"sku":"V40C","price":23.65,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7ba871dbfc50dc545e26a501d56b33cd_af571e76-ee92-4ea9-96ac-1bac108fd978.jpg?v=1790056607","url":"https:\/\/voomisupply.com\/products\/gardner-spring-v40c-extension-spring-18-67-lb-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
