Supco

Founded in 1945 in the Bronx, NY by two naval engineers, Sealed Unit Parts Co.,Inc (SUPCO) originated as a service company for refrigeration systems. SUPCO developed the first electronic vacuum gauge in 1990. During the latter part of the decade, master distributor partnerships for product lines, such as Therm-o-disc components, bolstered SUPCO's position as a key supplier to the HVAC/R and Appliance wholesale distributors.
