It features a 0.36-inch outside diameter, a 0.049-inch wire diameter, and a spring rate of 18.1 pounds per inch. With an initial tension of 1.2 pounds and a maximum extended length of 1.2 inches, this spring is suited for applications that require controlled resistance to stretching. It is commonly installed by HVAC technicians, appliance service pros, and mechanical equipment specialists working on light-duty assemblies requiring precise spring return force.\u003c\/p\u003e\u003cp\u003eThis extension spring fits compact mechanical assemblies where space is limited and consistent return tension is critical. Typical applications include damper linkages, small actuator assemblies, door latch mechanisms, and light-duty control linkages found in HVAC equipment and related trade hardware. The compact outside diameter and short extended length make it appropriate for tight-clearance installations inside equipment enclosures or panel assemblies.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.36-inch outside diameter for compact, tight-clearance fitment\u003c\/li\u003e\n\u003cli\u003e18.1 pounds per inch spring rate for consistent, predictable tensile resistance\u003c\/li\u003e\n\u003cli\u003e0.049-inch wire diameter providing durability in light-duty cycling applications\u003c\/li\u003e\n\u003cli\u003e1.2-inch maximum extended length suited for short-travel linkage assemblies\u003c\/li\u003e\n\u003cli\u003e1.2-pound initial tension for controlled preload without slack\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 0.36-inch OD, 0.049-inch wire diameter, and 18.1 pounds per inch spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eExtension springs of this type are installed by HVAC technicians or mechanical service professionals. Power down or de-energize the equipment fully before servicing any spring-loaded linkage. Use appropriate hand tools and eye protection when stretching or seating extension springs, as stored tension can cause the spring to release unexpectedly. Verify the replacement spring rate and extended length match the original specification before installation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.36 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.049 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Extended Length\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 18.1 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInitial Tension\u003c\/strong\u003e: 1.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.4 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: 36-49-1370\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51961859539250,"sku":"36-49-1370","price":17.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/450f24091e6ef945704e0a0bbf491eaf_33a508b4-3490-4f11-9978-b15d364f1c9f.jpg?v=1789947323","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36-49-1370-extension-spring-0-36in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
