With an outside diameter of 0.0938 inches (3\/32 inches), a free length of 0.625 inches (5\/8 inches), and a wire diameter of 0.012 inches, this spring is built for compact assemblies where precise load control matters. It delivers a spring rate of 1.3 lb\/in with a maximum work load of 0.87 lb and an initial tension of 0.10 lb. The plain stainless steel finish resists corrosion without added coating. Technicians and assemblers working with small mechanical linkages, damper actuators, or control components will find this spring a reliable fit for tight-clearance installs.\u003c\/p\u003e\n\u003cp\u003eThis extension spring is suited for residential and light commercial applications where small tension springs appear in control linkages, damper assemblies, HVAC equipment panels, and general mechanical subassemblies. Its compact geometry  -  0.625 inches free length and a maximum extended length of 1.22 inches  -  makes it appropriate for confined spaces with limited travel. It is sold in a package quantity of 3, making it practical for service trucks and shop stock where spares are kept on hand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eStainless steel construction with plain finish for corrosion resistance in humid or washdown environments\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 1.3 lb\/in for predictable, linear load response\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 0.87 lb with initial tension of 0.10 lb\u003c\/li\u003e\n  \u003cli\u003eOutside diameter of 0.0938 inches (3\/32 inches) fits compact mechanical clearances\u003c\/li\u003e\n  \u003cli\u003eMaximum extended length of 1.22 inches limits overextension in fixed-travel assemblies\u003c\/li\u003e\n  \u003cli\u003ePackaged in quantities of 3 for easy stocking and replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-replacement or supplemental extension spring for compact mechanical assemblies requiring a 3\/32 inches OD, 5\/8 inches free length stainless steel extension spring with a 1.3 lb\/in spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by HVAC technicians, mechanical assemblers, or equipment service technicians. Always de-energize and isolate equipment before accessing internal spring components. Use appropriate small-part handling tools to avoid overextending the spring beyond its 1.22 inches maximum extended length, as exceeding this limit can cause permanent set or failure. Follow the equipment manufacturer's service documentation for correct hook attachment points and orientation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 0.87 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 1.3 lb\/in\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 0.10 lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.0938 inches (3\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.012 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length (Overall Length)\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.22 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInside Hook Length\u003c\/strong\u003e: 5\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 lb\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: 37013GS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52100787929394,"sku":"37013GS","price":17.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0e5d5ee845c15304afe498237a697a41_9aa1e101-c7f1-4f74-95aa-e7891a974446.jpg?v=1790069326","url":"https:\/\/voomisupply.com\/products\/gardner-spring-37013gs-extension-spring-0-87-lb-max-load","provider":"Voomi Supply","version":"1.0","type":"link"}
