With a 0.25-inch outside diameter and a 0.031-inch wire diameter, this spring delivers a spring rate of 3.3 pounds per inch and a maximum work load of 4.52 pounds. The plain finish stainless steel construction resists corrosion in exposed or high-humidity environments. This part ships in a package quantity of three, making it suitable for multi-unit repairs or small-batch assembly work performed by mechanical technicians and trade professionals.\u003c\/p\u003e\n\u003cp\u003eThe 37040GS is appropriate for applications requiring a compact, low-profile extension spring with a free length of 1.5 inches and a maximum extended length of 2.66 inches. Common installation scenarios include damper linkages, equipment latches, control assemblies, and light tensioning mechanisms found in residential and light commercial HVAC equipment and mechanical systems. The 0.7-pound initial tension ensures consistent preload at the start of extension.\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 exposed environments\u003c\/li\u003e\n  \u003cli\u003eSpring rate of 3.3 lb per inch for predictable, linear tensioning force\u003c\/li\u003e\n  \u003cli\u003eMaximum work load of 4.52 pounds with 0.7-pound initial tension preload\u003c\/li\u003e\n  \u003cli\u003eCompact 0.25-inch outside diameter fits tight clearance installations\u003c\/li\u003e\n  \u003cli\u003eMaximum extended length of 2.66 inches from a 1.5-inch free length\u003c\/li\u003e\n  \u003cli\u003eSold in a package of three pieces for multi-unit or backup inventory use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement extension spring for light-duty mechanical and HVAC equipment assemblies requiring a 0.25-inch OD, 1.5-inch free length stainless steel extension spring with a 3.3 lb per inch spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of extension springs should be performed by a qualified technician familiar with the equipment being serviced. Disconnect power and relieve any system tension before removing the existing spring. Use appropriate spring hooks or pliers designed for small-diameter springs to avoid overstretching beyond the maximum extended length of 2.66 inches, which can permanently deform the spring. Do not exceed the rated maximum work load of 4.52 pounds during installation or operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 4.52 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 3.3 lb per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 2.66 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\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: 0.02 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: 37040GS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52099414851890,"sku":"37040GS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/33bd9ec715c3186b0d1d83476e2eb39a.jpg?v=1790068253","url":"https:\/\/voomisupply.com\/products\/gardner-spring-37040gs-extension-spring-stainless-steel","provider":"Voomi Supply","version":"1.0","type":"link"}
