It features a 0.3-inch outside diameter, a free length of 0.687 inches, and a wire diameter of 0.022 inches. The spring delivers a rated spring rate of 3.91 lb\/in and supports a maximum work load of 2.17 pounds. Closed and ground ends provide stable seating and uniform load distribution. This part is suited for instrumentation, HVAC actuators, valves, and other mechanical control components where dimensional precision and corrosion resistance are required.\u003c\/p\u003e\u003cp\u003eThis compression spring fits applications in residential and commercial mechanical systems where a compact, small-diameter spring is needed. Typical installations include valve assemblies, actuator mechanisms, relay components, and precision instrument housings. Its stainless steel construction makes it appropriate for environments with exposure to moisture or mild corrosives. Engineers, technicians, and assemblers working with control hardware will find this spring meets tight dimensional tolerances required in production and field repair contexts.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePrecision spring type with closed and ground ends for stable, flat seating under load\u003c\/li\u003e\n\u003cli\u003eStainless steel construction (AISI 302) provides corrosion resistance in harsh or humid environments\u003c\/li\u003e\n\u003cli\u003e0.3-inch outside diameter fits a 0.312-inch hole diameter for close-clearance installations\u003c\/li\u003e\n\u003cli\u003eSpring rate of 3.91 lb\/in supports predictable load-deflection behavior across the working range\u003c\/li\u003e\n\u003cli\u003eMaximum work load of 2.17 pounds with a solid height of 0.128 inches\u003c\/li\u003e\n\u003cli\u003eMeets AISI 302, ASTM A228, and ASTM A313 material standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a precision replacement or OEM-style component for mechanical assemblies requiring a small-diameter compression spring with closed and ground ends in stainless steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of compression springs in valve, actuator, or relay assemblies should be performed with the system depressurized and de-energized before service. Use appropriate hand tools and spring installation fixtures to avoid overstressing the spring during seating. Verify that the mating bore or guide pin matches the specified hole diameter and wire clearance before assembly. Consult applicable equipment service documentation and any relevant mechanical codes for proper spring replacement procedures.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFree Length\u003c\/strong\u003e: 0.687 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.022 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSolid Height\u003c\/strong\u003e: 0.128 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter (Recommended Bore)\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring Rate\u003c\/strong\u003e: 3.91 lb\/in\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Work Load\u003c\/strong\u003e: 2.17 pounds (9.66 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\u003eSpring Type\u003c\/strong\u003e: Precision\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\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\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.01 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: 36040GS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52094879596850,"sku":"36040GS","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0994fe5420b60d7f87f56efa935bf782.jpg?v=1790065440","url":"https:\/\/voomisupply.com\/products\/gardner-spring-36040gs-precision-compression-spring","provider":"Voomi Supply","version":"1.0","type":"link"}
