Decades of Experience Providing High-Quality Sealing Solutions to OEMs.

Colonial Seal Company was founded in 1994 by Vietnam-Era USMC Veteran, Stephen Maloney and quickly established itself as an important distributor of high-quality oil seals, O-rings, and hydraulic seals. In 2000, the company acquired Advanced Seal Technologies which designs and manufactures custom lathe-cut seals. ISO 9001 certification was attained in 2008 for the distribution and design support of sealing products used in industrial and automotive applications. In May 2023 the company acquired SSP Manufacturing.
