It features a 0.312-inch outside diameter and a 0.0286-inch wire diameter, giving it a compact cross-section suited for tight clearances. With a spring rate of 0.76 lb\/in and a maximum work load of 2.77 pounds, it delivers consistent, predictable force through its travel range. The free length is 2.0 inches and the maximum extended length is 5.09 inches. Sold in packages of 6, this spring is a practical stocking item for service technicians and maintenance professionals who routinely replace worn or broken extension springs during equipment service calls.\u003c\/p\u003e\u003cp\u003eThis spring suits applications where a small-format extension spring is needed to maintain tension, close a damper, return a lever, or hold a component in a resting position. Typical use cases include HVAC damper linkages, control panel latches, appliance mechanisms, and light-duty machinery. Its compact OD and predictable spring rate make it a reliable drop-in for similar-specification springs in residential and light commercial equipment. The package quantity of 6 supports bench-stocking needs for service fleets.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.312-inch outside diameter fits tight clearance installations\u003c\/li\u003e\n\u003cli\u003e0.76 lb\/in spring rate provides consistent, linear return force\u003c\/li\u003e\n\u003cli\u003e2.77 lb maximum work load suitable for light-duty tensioning\u003c\/li\u003e\n\u003cli\u003eFree length of 2.0 inches with maximum extended length of 5.09 inches\u003c\/li\u003e\n\u003cli\u003e0.0286-inch wire diameter for fine-pitch coil construction\u003c\/li\u003e\n\u003cli\u003eSold in a package of 6 for convenient bench stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or stocking extension spring for light-duty mechanical and HVAC-related assemblies requiring a 0.312-inch OD, 2.0-inch free length spring with a 0.76 lb\/in spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs should be installed by a qualified technician familiar with mechanical assembly procedures. Before replacing a spring, de-energize and lock out any powered equipment per applicable safety codes. Inspect mounting hooks and anchor points for wear or deformation before installing a new spring. Do not stretch the spring beyond its rated maximum extended length of 5.09 inches, as exceeding the maximum work load can cause permanent deformation or failure.\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: 2.0 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 5.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 0.76 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: 0.05 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: E18C-SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51971269591346,"sku":"E18C-SS","price":16.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7f5d5bbd0cb4c172042ac3af3109a1e2_67e6c4d2-56a1-42eb-a825-18b7893f3bde.jpg?v=1789955248","url":"https:\/\/voomisupply.com\/products\/gardner-spring-e18c-ss-extension-spring-0-312-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
