Seals and O-Rings

Seals are small components with outsized consequences. A failed seal lets contamination in and lubricant out—taking bearings, gearboxes, pumps, and hydraulic systems down with it. Specifying the right seal is one of the cheapest reliability improvements available.

KSIS supplies oil and grease seals, O-rings and O-ring kits, pump and mechanical seals, hydraulic rod and piston seals, shaft repair sleeves for worn sealing surfaces, and gaskets and packing. We can match dimensions and materials to your application—including high-temperature, chemical-resistant, and food-grade compounds.

Bring us a worn seal or the equipment specs, and KSIS will identify and source the correct replacement, in the material your service conditions demand.
