It features a 0.42-inch outside diameter, a 2-inch free length, and a 0.047-inch wire diameter. The spring delivers a rated spring rate of 11.5 pounds per inch and a maximum working load of 15 pounds. Closed and ground ends provide flat, stable seating surfaces for consistent axial loading. This spring suits maintenance technicians, mechanical assemblers, and trade professionals who require a reliable, spec-grade compression spring for precision mechanical applications.\u003c\/p\u003e\n\u003cp\u003eThis spring is commonly used in HVAC equipment, plumbing assemblies, electrical enclosures, and general mechanical systems where controlled compression force is required. Its compact form factor and precision tolerances make it suitable for valve assemblies, actuator mechanisms, latching hardware, and similar load-bearing spring applications in both residential and light commercial equipment. Solid height of 0.683 inches limits travel and prevents coil bind under maximum load conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.42-inch outside diameter with 0.438-inch recommended hole diameter for guided installation\u003c\/li\u003e\n  \u003cli\u003e11.5 pounds per inch spring rate for predictable, linear compression response\u003c\/li\u003e\n  \u003cli\u003e15-pound maximum working load rated capacity\u003c\/li\u003e\n  \u003cli\u003eClosed and ground end type for flat seating and accurate load transfer\u003c\/li\u003e\n  \u003cli\u003eMusic wire construction meets AISI 302, ASTM A228, and ASTM A313 standards\u003c\/li\u003e\n  \u003cli\u003e0.683-inch solid height limits coil bind under full compression\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision OEM-style compression spring for mechanical assemblies requiring a 0.42-inch OD, 2-inch free length, closed and ground end spring with an 11.5 pounds per inch spring rate.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by mechanical technicians or trade professionals familiar with spring-loaded assemblies. De-energize or depressurize the system before replacing any spring component. Use the recommended 0.438-inch hole diameter for guided-fit installation to maintain proper axial alignment and prevent buckling under load. Do not compress the spring below its solid height of 0.683 inches during assembly or testing.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.42 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.047 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.683 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 11.5 pounds per inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Load\u003c\/strong\u003e: 15 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRecommended Hole Diameter\u003c\/strong\u003e: 0.438 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Closed and Ground\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Music Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Plain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: AISI 302, ASTM A228, ASTM A313\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Precision\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161904\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: 36449G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52112305094962,"sku":"36449G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bc2e8aac5b34d59686c5cc7d961937cf.jpg?v=1790077564","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36449g-precision-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
