WATER PUMP SEALS

H68U

  • Unitised Seal
  • One-Piece Cartridge Type
  • Press-Fitted Into Housing
  • Shaft Sealing
  • Suits Automotive Pumps

H68U is a unitised, cartridge-type

version of the H68. The rotating and

stationary assemblies are crimped together during manufacture and supplied as a single, one-piece unit.

 

The seal has multiple points of sealing. Aside from the sealing faces, leakage is prevented over the shaft as well as the stationary housing bore due to the tight tolerance fit (tool recommended).
