H68C

  • Rubber cup push fit
  • Higher operating speeds

PARTS

H68C uses the same parts as the H68 but relies on an additional rubber cup (C) that fits over the head.

 

It is best suited for applications where the cavity / bore may be worn (i.e. made from cast-iron). The cup provides greater friction-resistance and allows the seal to run at higher operating speeds.
