It features a 0.72 inch outside diameter, a 2.5 inch free length, and a 0.0669 inch wire diameter. The spring delivers an 18.0 pound maximum work load and a 13.75 pound-per-inch spring rate, making it suited for applications requiring consistent, repeatable force over a defined travel range. Closed and ground ends provide flat, stable seating surfaces. This part is appropriate for use by maintenance technicians, mechanical assemblers, and trade professionals working in HVAC equipment, plumbing assemblies, or industrial mechanisms where a compact, high-tolerance compression spring is required.\u003c\/p\u003e\n\u003cp\u003eThis spring fits into applications where the mating bore diameter is up to 0.75 inches. Its solid height of 0.725 inches and music wire construction make it a practical choice for medium-load compression duties in residential and light commercial equipment. Typical install scenarios include valve assemblies, actuator mechanisms, and component retention applications where a precision-grade spring is specified. The silver plain finish indicates no additional coating, which is standard for indoor or protected environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.72 inch outside diameter with 0.75 inch maximum hole diameter fit\u003c\/li\u003e\n  \u003cli\u003e2.5 inch free length with 0.725 inch solid height\u003c\/li\u003e\n  \u003cli\u003e18.0 pound maximum work load and 13.75 lb\/in spring rate\u003c\/li\u003e\n  \u003cli\u003eClosed and ground end type for flat, stable seating\u003c\/li\u003e\n  \u003cli\u003eMusic wire construction per AISI 302, ASTM A228, and ASTM A313\u003c\/li\u003e\n  \u003cli\u003ePlain silver finish, no additional coating\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a precision-grade OEM-style compression spring for mechanical assemblies requiring a 0.72 inch OD and 2.5 inch free length specification.

De-energize and depressurize the assembly before removing the existing spring or installing this part. Ensure the mating bore and pilot dimensions are within specification before seating the spring. Confirm the compressed height does not exceed the solid height of 0.725 inches under maximum load conditions.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Precision Compression\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 18.0 pounds (97.86 N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 13.75 lb\/in\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: 0.0669 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.725 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\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\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: 36551G\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52081197744434,"sku":"36551G","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/024563d428703acdbf730cb5e74ed09a.jpg?v=1790056058","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36551g-precision-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
