Gardner Spring 36245G Precision Compression Spring

Product Description

The GARDNER SPRING 36245G is a precision compression spring manufactured from AISI 302 music wire with a plain silver finish. It features a 0.18-inch outside diameter and a free length of 1.5 inches, with a wire diameter of 0.0181 inches. The spring delivers a maximum working load of 2 pounds and a solid height of 0.3740 inches. Closed and ground ends provide stable seating and consistent load distribution. This part is suited for original-equipment and replacement applications across mechanical assemblies, HVAC equipment, and fluid-control devices where repeatable spring force in a compact form factor is required.

This spring is used in light-duty mechanical applications requiring a small-diameter, precision-wound compression spring. Typical installation scenarios include valve actuators, control linkages, solenoid return mechanisms, and similar sub-assemblies found in residential and light-commercial HVAC systems, plumbing valves, and general industrial equipment. Sold in packages of five, it is commonly stocked by maintenance technicians, OEM assemblers, and field service professionals who require interchangeable spare springs on hand.

Key Features

• Precision-wound construction to AISI 302, ASTM A228, and ASTM A313 standards for consistent load performance
• Closed and ground end type for flat, stable seating in bored or countersunk pockets
• 0.18-inch outside diameter fits holes up to 0.188 inches for snug, guided installation
• 2-pound maximum working load suitable for light-duty actuator and return-spring applications
• Solid height of 0.3740 inches limits compression travel and prevents coil-bind damage
• Plain silver finish on music wire resists deformation under repeated cycling

Compatibility

Designed as an OEM-style precision compression spring for mechanical assemblies, valve actuators, and control linkages where a 0.18-inch OD, 1.5-inch free-length spring meeting ASTM A228 or ASTM A313 specifications is required.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or mechanical assemblers as part of valve or actuator service. Power down or de-energize any electrical or pneumatic actuator before disassembling the component housing. Verify the hole diameter of the receiving bore matches the spring outside diameter before installation to ensure proper guidance and prevent buckling under load. Avoid stretching or pre-stressing the spring beyond its rated maximum work load during assembly.
