Gardner Spring 36050G Precision Compression Spring

Product Description

The GARDNER SPRING 36050G is a precision compression spring manufactured from music wire (AISI 302, ASTM A228, ASTM A313) with a plain silver finish. It features a 0.3 inch outside diameter, a 1.5 inch free length, and a 0.0382 inch wire diameter. The spring delivers a 13.5 lb/in spring rate and handles a maximum work load of 12.25 lb. Closed and ground ends provide stable seating and consistent force application. This type of small-format precision spring is used in mechanical assemblies, valve mechanisms, and equipment service applications across HVAC, plumbing, and industrial trades.

The 36050G suits applications requiring a compact, light-duty compression spring with predictable deflection characteristics. Its solid height of 0.571 inches and hole diameter of 0.312 inches make it compatible with close-tolerance bores and shafts common in valve bodies, actuators, and small mechanical components. Trade professionals sourcing OEM-style replacement springs or building custom assemblies will find this spring appropriate for residential and light commercial equipment where precise load and rate specifications are required.

Key Features

• 13.5 lb/in spring rate for consistent, predictable force across the compression range
• 12.25 lb maximum work load rating
• Music wire construction meets AISI 302, ASTM A228, and ASTM A313 standards
• Closed and ground ends for stable seating and reduced buckling tendency
• 0.312 inch hole diameter fits standard close-tolerance bore applications
• Plain silver finish suitable for general mechanical environments

Compatibility

Designed as a precision OEM-style compression spring for use in mechanical assemblies, valve mechanisms, and equipment components requiring a 0.3 inch OD, 1.5 inch free length spring with closed and ground ends.

Installation Notes

Compression springs of this type are installed by mechanical technicians working on valve assemblies, actuators, or small mechanical components. Confirm the mating bore and shaft dimensions match the 0.312 inch hole diameter and 0.3 inch outside diameter before installation. Inspect the spring seat surfaces for burrs or damage that could affect seating and load distribution. Follow all applicable equipment manufacturer service procedures when replacing springs in pressurized or energized systems.
