It features a 0.72-inch outside diameter and a 1-inch free length, making it a compact, high-cycle component suited for mechanical assemblies across HVAC equipment, plumbing fixtures, valves, and general industrial hardware. The spring delivers a 97 lb\/in spring rate and supports a maximum working load of 53 pounds. Closed and ground ends provide stable seating and consistent load transfer under compression. Technicians and assemblers working with OEM replacement components or custom mechanical builds will find this spring a direct-fit option where precise load characteristics are required.\u003c\/p\u003e\u003cp\u003eThis compression spring fits into applications where controlled force and consistent deflection are critical. It is commonly used in valve assemblies, actuator mechanisms, pump components, and similar hardware found in residential and light commercial HVAC, plumbing, and industrial systems. The 0.72-inch OD is sized to fit inside a hole diameter of 0.75 inches. Its compact 1-inch free length and 0.451-inch solid height allow installation in space-constrained assemblies. Sold in a package of 5 units with a minimum order quantity of 1.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.72-inch outside diameter with a 0.75-inch recommended hole diameter for a snug bore fit\u003c\/li\u003e\n\u003cli\u003e97 lb\/in spring rate for predictable, linear force response under load\u003c\/li\u003e\n\u003cli\u003e53-pound maximum working load capacity\u003c\/li\u003e\n\u003cli\u003eClosed and ground ends for flat, stable seating and accurate load application\u003c\/li\u003e\n\u003cli\u003eMusic wire construction meeting AISI 302, ASTM A228, and ASTM A313 standards\u003c\/li\u003e\n\u003cli\u003ePlain silver finish suitable for dry or lightly lubricated mechanical environments\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or aftermarket compression spring for mechanical assemblies requiring a 0.72-inch OD, 1-inch free length, closed and ground end compression spring with a 97 lb\/in spring rate.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by mechanical technicians or assembly technicians working on valve, actuator, or pump components. Always de-energize or depressurize the assembly before removing or installing compression springs to prevent uncontrolled release of stored energy. Confirm the bore diameter, free length, and spring rate match the application requirements before installation. Use appropriate hand tools and eye protection when compressing or seating the spring.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Precision Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.72 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.085 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.451 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 97 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 53 pounds (242.44 N)\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\u003ePackage Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 31161904\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: 36557G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":51971202416946,"sku":"36557G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9bbf1f7a6f4dee4a25ae9e42152113b.jpg?v=1789954599","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36557g-precision-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
