Square seal / Lathe cut / Die cut

Square Seals describe rectangular cross section seals. These are typically used as static face seals, static radial seals, bumpers, sleeves, dampeners, etc. They are manufactured by lathe cutting (“Lathe Cut seals”) or by die cutting (Die Cut seals). Lathe cut square seals are manufactured from a sleeve of rubber mounted to a mandrel and turned, with individual seals parted off using a radial cutting process. Die cut square seals are cut from sheet stock using a stamp die.

Special Applications

Optimized for static face seal, special consideration surface finish interface at cut face on lathe cuts, corner radii on molded versions.
