Control or multi-function valve/end cap interface seal
The parts enclosed in this kit may be used to seal the interface between either the control or multifunction valve and the end cap using either the “old” style end caps that used O-rings or the “new”
style end caps that use a gasket seal.
The mounting surface for a control or multi-function valve on the end cap determines which style
end cap your motor has. If there are O-ring spot faces on the mounting surface, use the enclosed
O-rings to seal the control interface. If there are no O-ring spotfaces, use the enclosed gasket seal.
