O.G. Supply has been in business since 1948 and has built a solid reputation around the world as an innovative sealing solution provider to the boiler and waterworks industry. With millions of hand-hole/man-hole and flange gaskets placed into service, we have become experts in the art of sealing high pressure/high temperature steam.

Our headquarters is located in Cibolo, Texas. Just 30 minutes from the heart of San Antonio. The 10,000 sq ft facility was built in 1988. In 2019 we added another 12,000 sq ft which includes a wide selection of industrial gasket manufacturing processes. While we specialize in high volume OEM components, we also have the ability to engineer or reverse engineer a sealing solution to help you meet your exact requirement, regardless of size, shape, or quantity.
