Overview
SO-HPP-SP1 is the spool-piston O-ring used in the 20% Clark Pump reversing-valve end blocks. The guide shows this seal in the bore groove before the spool piston is fitted.
The associated end-block bore is 1 inch, compared with 1-1/4 inches on the documented 7%/10% pumps. Select SP1 for the identified 20% arrangement; the “1 inch” description does not provide the seal’s full inside diameter and cross-section.
