Seals and Sealing Products

Seals, sealants & device sealing experts

Sealing Devices offers many types of seals from O-rings that seal water, aircraft fuels and many media on pumps, electronic devices, compressors, transportation vehicles, food processing equipment and medical devices, to complex EMI shielding gaskets that block electromagnetic interference in electronic enclosures and devices.

Seals prevent or reduce fluid passage between two surfaces. Imperfect mating parts require some type of sealing device to be inserted between them to seal against loss of liquid, gas, solid fluids or particles.

Sealing Devices also provides molded rubber seals, extrusions, lathe-cuts, gaskets, packing, Teflon seals, mechanical seals, graphite, cloth, metal seals, O-rings and metal rings, and a complete line of oil seals.
