Understanding This Part
A rod buffer seal is used ahead of the primary rod seal to help manage pressure fluctuations. Match the original buffer profile and its position in the sealing arrangement; a buffer seal and a back-up ring serve different roles.
Fitment Verification
Before ordering, confirm the KOM-707-51-70650 reference against your OEM reference number, machine model, cylinder location, bore and rod size, pump/motor series, and serial-number range. Manufacturer names and part numbers are used for identification and fitment reference only. If you are unsure, compare the old parts, measurements, and parts-book callout before installation.
