We Check Fitment Before We Quote

06 · Quality & Documents

Quality Checks on Precision Parts

If a plunger or valve plate is even slightly out of tolerance, the injection quantity can be wrong and the part can fail its bench test. We apply strict quality control to these parts, and we can provide documents so you can pass quality proof on to your own customers.

Quality Control

  • Checks on plungers and valve plates
  • Checks on ball seats and pump elements
  • Fitment checked against the OE number

On Request

  • Quality certificates
  • Samples before a volume order
  • Sales contract for each order
