PHYSICAL PROPERTIES
T-N11/N22 Seal Heads
Our T-N11/N22 type seal heads are designed with a reduced outer diameter, making them fully compatible with ANSI seal chamber dimensions. The rotary portion of our seal is typically smaller than the stationary seat, and can fit straight box bores where many other seals cannot.
These seals are direct replacements for industry-standard T-E / 1 heads as well as C / 21 models.
Note: The N11/N22 seal designs max shaft size is 2.25″. For larger shafts, please refer to our other seal types.
