FedPro, originally founded as Federal Process, manufactured its first can of Gasoila® Pipe Thread Sealant in 1915. Small batches were made to meet the high quality standards set by our founders. Those standards have not changed in 100 years. We still manufacture our chemicals in small batches so we can closely monitor the quality and reliability you've come to expect from FedPro. Our brands have earned a reputation for being the products of choice in the petroleum, plumbing, LP Gas, HVAC, automotive, hardware, and general industrial markets.
