What Martin Fluid Power(MFP Seals) does

Martin Fluid Power Company, Inc. — operating commercially as MFP Seals — is a U.S.-based manufacturer and distributor of hydraulic, pneumatic, and specialty sealing devices founded in 1977 and headquartered in Madison Heights, Michigan. The company operates through wholly-owned manufacturing subsidiaries covering horizontal and vertical injection molding of thermoplastics and elastomers (Plant 1, Madison Heights; IPMtek), CNC machining of plastics and elastomers up to 40-inch diameter (Plant 2, Madison Heights), and custom die cutting (Gad-Jets, Franklin, Ohio). Its product portfolio spans standard O-rings and backup rings, hydraulic/pneumatic seals, spring-energized seals (XS Seal®), oil and grease seals, bushings and wear rings, sanitary gaskets, oil & gas-specific sealing kits rated to 15,000 PSI, and Michael-Stephens branded seal repair kits interchangeable with major OEM equipment. MFP Seals formulates and sells proprietary compound lines including Fluorochem® perfluoroelastomers (FFKM grades qualified to AMS 7257, NORSOK M710, FDA, and USP Class VI), Ultraflex™ thermoplastic polyurethanes, X-Pac® and O-Pac® U-cup seals, and Hydrowype metallic wipers, with quality controlled by a non-contact vision measuring system accurate to 0.4 µm.

The company's go-to-market is direct sales-led via territory managers and customer service teams at eight stocking locations across the U.S. (Madison Heights, Troy, St. Joseph, Tampa, Phoenix, Houston), the U.K. (Lincoln), and Taiwan (Taipei), supported by an RFQ-based quoting system rather than transactional e-commerce, and by participation in industry events such as the Design 2 Part Show and IFPE. Customer segments are vertically organized, with primary exposure to oil & gas (BOP seals, hammer unions, wellhead seals qualified for sour service) and mobile equipment/industrial hydraulics (mining, construction, agricultural aftermarket), and secondary applications in aerospace, semiconductor, food/pharmaceutical/sanitary, and mining. Distribution is augmented by resale partnerships with Simriz (Freudenberg-NOK Simrit FFKM compounds), Hydrowype metallic wipers, Claron Polyseal piston seals, Hallite metric piston seals, and Michael-Stephens seal kits. The company is privately held, appears founder/family-controlled under CEO Mike King and President Ryan King, holds CAGE Code 0X8S1 for government contracting, and does not publicly disclose revenue or accept outside institutional investment per the available material.
