U.S. SEAL MFG.

U.S. Seal MFG, a subsidiary of Smiths Group, is a long-established American manufacturer specializing in mechanical seals for pump applications. The company claims coverage of approximately 95% of the replacement mechanical seal market, offering seals in configurable combinations of elastomer, metallurgy, and sealing face materials. Their industrial seal line features precision-lapped faces (flat to one to three light bands) that provide automatic self-adjustment, contamination-free sealing, and reduced horsepower consumption compared to gland packing. The Pool & Spa division produces three seal tiers: Basic Service (Buna elastomer, molded plastic primary ring, ceramic seat) for residential chlorine pools; Premier Viton Service (Viton elastomer, carbon primary ring, polished ceramic seat) for ozone, salt chlorine, and bromine applications; and SCS Commercial Service (Viton elastomer, silicon carbide primary ring and seat, 316 stainless hardware) for the most demanding commercial environments. A dedicated Flygt Replacement Seal line provides aftermarket seals for Xylem/Flygt submersible pumps. The company operates an e-commerce portal at ussealmfgexpress.com and supports distributors with a seal identification form, Spanish-language resources, and a nationwide representative network. The technical staff holds over 75 years of combined seal industry experience.
