Built with a 0.016-inch wire diameter and a 0.125-inch outside diameter, this spring delivers a spring rate of 1.3 lb\/in and handles a maximum work load of 1.39 pounds. The overall free length is 1.0 inch, and it extends to a maximum of 1.91 inches under load. Each package contains 3 pieces, making it practical for service stock, prototype builds, or small repair jobs. Licensed technicians and maintenance professionals working with precision mechanisms will find this spring sized for accurate fitment in confined spaces.\u003c\/p\u003e\u003cp\u003eThis extension spring is suited for residential and commercial mechanical assemblies where consistent return force and compact dimensions are required. Common applications include HVAC equipment linkages, control panel mechanisms, appliance components, and light industrial hardware. Its small OD and low wire diameter make it a practical choice anywhere a fine-pitch, low-load extension spring is called for. Installers sourcing replacement springs for similar free-length and load requirements will find the published specs sufficient for direct comparison against existing components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.125-inch outside diameter for compact, space-constrained installations\u003c\/li\u003e\n\u003cli\u003eSpring rate of 1.3 lb\/in provides consistent, predictable extension force\u003c\/li\u003e\n\u003cli\u003eMaximum extended length of 1.91 inches with a 1.0-inch free length\u003c\/li\u003e\n\u003cli\u003e0.016-inch wire diameter for fine-pitch, light-load tension applications\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 1.39 pounds keeps stress within safe operating range\u003c\/li\u003e\n\u003cli\u003eSold in a 3-piece package, convenient for service stock and repair inventory\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 requiring a 1\/8-inch OD, 1.0-inch free length, and 1.3 lb\/in spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs should be installed by qualified technicians familiar with spring-loaded mechanism service. Always de-energize or fully relieve tension from the host assembly before removing or installing springs. Avoid overstretching beyond the published maximum extended length of 1.91 inches, as exceeding this limit can permanently deform the spring and reduce load capacity. Verify that hook orientation and inside hook dimensions are compatible with the mounting points in the host assembly before final installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.016 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.91 inches\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\u003eMaximum Work Load\u003c\/strong\u003e: 1.39 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 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: 37018GS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52027651785010,"sku":"37018GS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26c7620502c0637bd7e56a3d6b71e925.jpg?v=1790017249","url":"https:\/\/voomisupply.com\/products\/gardner-spring-37018gs-extension-spring-1-8-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
