H68U

  • Stationary-based Design
  • Compact
  • Cavity Seal

H68U is the unitised, cartridge  version of the H68. The seal head and seat are crimped together during manufacture and supplied as a single unit. The seal has three points of sealing;   the seal faces, at the bore and  at the shaft. As it is shaft sealing, shaft size is a critical dimension.

 

The unitised design holds the lapped and polished seal faces together during storage and transport which avoids damage and contamination of these key components.
