Center Seals ♦ Custom Seals ♦ DIN Seals ♦ Double Face Seals  ♦ Large Diameter Seal Faces ♦ Seats ♦ O-Ring Seals 

We thrive on unique geometries, yet still welcome typical designs. Small diameter capabilities to 0.25" [6mm], and large diameter designs up to 27" [700mm] in silicon carbide and 18" 450 mm] in tungsten carbide. 

We provide axial designs, including seal faces in mechanical seals. We offer all types, standard and custom, as well as steam joints and valve seats. We also offer radial designs, including multi-segmented rings, shaft seals, gas seals, control rings, and seals for regulating devices.

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:
