What Clean Seal, Inc. does
Clean Seal, Inc. is a privately held, founder-owned manufacturer of extruded rubber seals, gasket profiles, and automotive hoses, founded in 1978 by Juanita Moore and headquartered in South Bend, Indiana. The company was established to commercialize extruded rubber seals as a clean alternative to the sticky butyl seal materials then in use for window and door applications, and has since expanded into a multi-vertical industrial supplier. Its product portfolio is organized into five categories: extruded seals and gasket profiles (D-sections, P-sections, U-channels, cord stock, pedestal sections, rectangles/squares, triangles, bar stock, ribbed/miscellaneous sections, silicone profiles); Clean Grip profiles (edge trim, trim seals, spring grip seals, dual durometer); automotive hose products (SAE J20R3 heater hose, Nomex heater hose, gas tank and soft wall fuel fill hose, SAE 30R7 standard premium fuel line, Low Perm CARB Tier III hose, SAE 30R14T2 high-pressure fuel hose, windshield wiper/vacuum tubing, molded and formed hoses, thermal reflective sleeve); Clean Trim Moldings (aftermarket universal moldings, lip trim, drip rail); and Splicing and Die Cutting Services (cold glue and hot vulcanizing splices, custom cut-to-length, drilling, notching, die cutting). The core technology is a rubber extrusion process producing constant cross-section profiles with a natural skin surface and closed-cell construction, with material options including EPDM, silicone, nitrile, and polychloroprene.
The company operates a sales-led, direct-to-customer go-to-market model staffed by experienced sales personnel and in-house customer service, supported by a 2026 product catalog, downloadable technical literature, social media presence (LinkedIn, Facebook, X), and industry trade show participation including IBEX for the marine industry. Pricing is quote-based and not publicly disclosed, with a $125 minimum per line item for domestic shipments and $300 for international; warehouse stock items are available in quantities as low as 100 feet and many ship within 24 hours. Revenue is generated from one-time sale of finished extruded rubber seals, automotive hoses, and aftermarket trim moldings, plus value-added custom manufacturing services (cutting, splicing, die cutting) where tooling and die charges may apply. The company is ISO 9001:2015 certified and holds CARB Tier III (EO# Q-19-082) and CARB LEV II (EO# Q-19-156/Q-19-002) regulatory certifications on regulated fuel hose products, serving OEMs, marine, RV, automotive aftermarket, and transportation industry customers from a single South Bend, Indiana facility with international shipping capability.
