Built from steel with a wire diameter of 0.04 inches and a coil outside diameter of 0.309 inches, this spring delivers 1.473 in\/lb of torque at leg length across a 90-degree deflection angle. With 4.25 active coils and a leg length of 1.25 inches, it provides consistent, repeatable performance in compact spring-loaded mechanisms. Technicians and assemblers working on OEM repairs or custom fabrications will find this part a direct-fit solution where small-format torsion springs are specified.\u003c\/p\u003e\n\u003cp\u003eThis torsion spring is suited for use in residential and light commercial mechanical systems where a right-hand wound, small-diameter spring is required. Typical applications include damper actuators, control linkages, door latches, and spring-return mechanisms found in HVAC equipment and electromechanical assemblies. A maximum tool size of 0.187 inches and a rod size of 0.187 inches define the inner fitment geometry. Sold in packages of 6 with a minimum order quantity of 1, this spring supports both single-unit repairs and small-batch production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree deflection angle for precise angular spring-return applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand direction of wind for standard torsion spring orientations\u003c\/li\u003e\n  \u003cli\u003e0.309 inch coil outside diameter fits compact spring pockets and housings\u003c\/li\u003e\n  \u003cli\u003eSteel construction provides durability in mechanical and HVAC assemblies\u003c\/li\u003e\n  \u003cli\u003e1.473 in\/lb torque at leg length for predictable load performance\u003c\/li\u003e\n  \u003cli\u003e4.25 coils with 1.25 inch leg length for consistent deflection geometry\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service torsion spring for mechanical assemblies requiring a right-hand wound spring with a 0.309 inch outside diameter, 0.04 inch wire diameter, and 90-degree deflection angle.

Relieve all system tension and de-energize any associated actuators or motors before removing the existing spring. Use appropriately sized tools matching the 0.187 inch maximum tool size to avoid deforming the spring coils during installation. Inspect the mounting rod, housing bore, and adjacent hardware for wear before fitting the replacement spring.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDeflection Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDirection of Wind\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Outside Diameter\u003c\/strong\u003e: 0.309 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWire Diameter\u003c\/strong\u003e: 0.04 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Coils\u003c\/strong\u003e: 4.25\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLeg Length\u003c\/strong\u003e: 1.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTorque at Leg Length\u003c\/strong\u003e: 1.473 in\/lb\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Tool Size\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRod Size\u003c\/strong\u003e: 0.187 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel\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: 0.02 pounds\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: GT4018709-MR\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GARDNER SPRING","offers":[{"title":"Default Title","offer_id":52075685708082,"sku":"GT4018709-MR","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/af2236f13437983eb872cd0f43db0410.jpg?v=1790052068","url":"https:\/\/voomisupply.com\/products\/gardner-spring-gt4018709-mr-torsion-spring-90-deg-0-309-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
