It measures 0.688 inches outside diameter and 1.25 inches free length, with a wire diameter of 0.0909 inches and a solid height of 0.68 inches. The spring delivers a spring rate of 84.6 pounds per inch and supports a maximum work load of 40.2 pounds. Closed ends provide stable seating on flat surfaces without additional hardware. This part is suited for use by mechanical maintenance technicians, industrial service professionals, and tradespeople working on equipment that requires a compact, corrosion-resistant compression spring.\u003c\/p\u003e\u003cp\u003eThe SS-18M is appropriate for light-duty mechanical assemblies across HVAC, plumbing, electrical, and general industrial applications. Its stainless steel construction makes it well suited for environments where moisture, mild chemicals, or temperature cycling would degrade carbon steel alternatives. The closed end design and utility classification make it a straightforward drop-in for standard spring seats in valves, latches, switches, and similar components. Package quantity is 6 units per pack.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eStainless steel construction resists corrosion in wet or chemically active environments\u003c\/li\u003e\n\u003cli\u003eClosed end type provides flat, stable seating without grinding or additional machining\u003c\/li\u003e\n\u003cli\u003eSpring rate of 84.6 pounds per inch for consistent, predictable load response\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 40.2 pounds suits light-duty mechanical assemblies\u003c\/li\u003e\n\u003cli\u003eCompact 0.688 inch OD and 1.25 inch free length fits tight clearance applications\u003c\/li\u003e\n\u003cli\u003ePlain finish maintains dimensional tolerances with no added coating buildup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service stock utility compression spring for mechanical assemblies requiring a 0.688 inch OD, 1.25 inch free length, closed-end stainless steel spring.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of compression springs is typically performed by mechanical or maintenance technicians as part of valve, switch, or mechanical assembly service. De-energize and relieve all pressure or tension from the assembly before removing the existing spring. Ensure the spring seat surfaces are clean and free of debris to allow proper seating of the closed ends. Do not compress the spring beyond its solid height of 0.68 inches during installation or operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.688 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.0909 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.68 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 84.6 pounds per inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 40.2 pounds (178.81 N)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Closed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Type\u003c\/strong\u003e: Utility\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Stainless Steel\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\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\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: SS-18M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52000701481266,"sku":"SS-18M","price":17.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f467eadc624385983a0c3dc366592f7d.jpg?v=1789996614","url":"https:\/\/voomisupply.com\/products\/gardner-spring-ss-18m-utility-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
