About Colonial Seal

Colonial Seal Company was founded in 1994 by Vietnam-Era USMC Veteran, Stephen Maloney, and established itself as a distributor of oil seals, O-rings, and hydraulic seals. The company acquired Advanced Seal Technologies in 2000, which designs and manufactures custom lathe-cut seals. Colonial Seal obtained ISO 9001: 2015 certification in 2008 for the distribution and design support of sealing products used in industrial and automotive applications, and in May 2023 the company acquired SSP Manufacturing. The company currently operates out of a 10,000 square foot distribution facility in Westville, New Jersey and a 2,500 square foot manufacturing facility in Gibsonia, Pennsylvania.
