* The complete seal part number consists of the basic part number plus the material dash number plus CW (clockwise) or CCW (counter-clockwise), designating the shaft rotation direction; e.g., 432-8-11 CW. The shaft rotation direction is determined relative to the lubricant end of the seal. Actual diameter varies as a function of material selected. New tooling may be required for certain materials.

** For gland details, see Chapter D5 of the Kalsi Seals Handbook. Gland depth can be varied to achieve specific objectives; see handbook.

*** Non-standard cross-sectional size

‡ PN 432-8-* has a wider footprint compared to PN 432-4-*.
