This bond then prevents lubricant from escaping. Colonial Seal Company supplies an extensive range of standard and non-standard oil or grease seals for a variety of mechanical applications. We offer general purpose and special purpose seals in several styles and materials. We can supply custom made seals to OEM drawings and specifications. Our oil seals are used in an extensive range of applications such as bearings, electric motors, gear reducers and a variety of pumps.
