Solon Manufacturing Company

Established in 1949, Solon Manufacturing Co. is an ISO 9001:2015 registered company that designs and manufactures industrial products used across every industry that employs bolted connections or requires gas, pressure, or liquid density measurement. Solon® Belleville Springs & Washers maintain bolt preload and keep bolted connections tight. They are particularly useful where vibration, differential thermal expansion, relaxation and bolt creep/yield are problematic. Electro-mechanical and pneumatic Solon® Pressure Switches control and monitor operating conditions and are critical in fluid or gas control. Solon® SF6 Gas Density Switches for high voltage circuit breakers measure and regulate SF6 gas density and leakage over a wide temperature range.
