The 72377SCS compression spring is a meticulously engineered component designed for a wide range of industrial applications requiring reliable performance and durability. Crafted from premium 0.082" diameter 302/304 stainless steel, the 72377S spring design exhibits reliable strength across its 10.4 active coils, withstanding repeated compression cycles with a maximum load of 18.1 lbf without succumbing to fatigue.

We manufacture the 72377S design to provide a compression spring that is 3.5" long at rest and provides a consistent rate of 9.4 lbs/in along its recommended maximum of 1.921" deflection. For best results, your application should fully accommodate the inner (0.813") and outer (0.975") diameters of this spring and be designed for its closed & ground end configuration.
