JJISCO specializes in large seal face components in custom and semi-standard designs to meet your size, shape, and hard material requirements. Our products aid in minimizing down time and increasing production. These seals will operate at temperatures up to 1500°C in corrosive, abrasive environments.

We thrive on unique geometries, and yet still welcome typical designs. JJISCO has large diameter capabilities up to 27" [700mm] in silicon carbide and 18" [450mm] in tungsten carbide.

In mechanical face and sealing applications, wear can occur due to diverse environmental conditions, abrasive media, slurries, and shaft deflections. This may ultimately cause a complete failure of the seal.

JJISCO offers the following material options to ensure our seals will meet your application needs:
