Mechanical Seals - All Spa Pumps

We stock standard and silicon carbide mechanical seals.

Standard seals are manufactured with carbon primary ring, ceramic seat, buna elastomers and stainless steel hardware and are the normal mechanical seals used in new pumps and sold as replacement seals.

Silicon Carbide seals are premium seals manufactured from superior materials and have silicon carbide primary ring and seat, viton elastomers and stainless steel hardware. They have excellent abrasion, corrosion and chemical resistance and more forgiving when dry run.
Silicon Carbide seals are available in a select range covering most of the currently used common spa pumps, but not all.
