The Hypro Leather Cup Kit typically repairs problems associated with reduced pressure, or leaking from the front of the pump. Works on the Hypro 5210C and 5210C-H Piston Pumps, but also works on the 5206C and 5206C-H Piston Pumps.

The Leather Cup Kit 3430-0037 consists of the following parts:

  • 2 x Piston Cap Screws (2220-0013)
  • 2 x Washers (2270-0012)
  • 2 x O-Rings (1720-0030)
  • 2 x Leather Cups (2150-0001)
  • 2 x O-Rings (1720-0065)
  • 2 x Seal Rings (1440-0012)

It is strongly recommended that you also purchase the item Pair of O-Rings for Cylinder Head (1720-0028x2), because the o-rings are difficult to replace/remove when swollen with chemical, and can break easily. In addition, it is the perfect opportunity to replace these parts since the pump has already been partly disassembled to install the Leather Cup Kit.

Only by Rittenhouse! We have created a new repair kit for the 5210 Hypro Pump and the part number is 3430-0037special. It is the exact same as the 3430-0037 Repair Kit with the addition of the piston guides. Make your rebuild complete.


  1. The Leather Cup Kit fixes most problems associated with the 5210C.
  2. Leather cups have superior chemical resistance to rubber cups.
