Rubber Priming/Filling Plug

Shipping information

The rubber priming plug sits in the filling hole in the reservoir recess and provides a connection for priming, as well as a seal against the elements and it allows the system to breathe.

The rubber priming plug has a female luer which connects to either the breather tube in normal use, the Lube Tube or Magnum HCR Tank (if an accessory has been added), or the filling & priming spout on the oil bottle to prime the system.


This rubber priming plug has to be taken off if you want to fill the reservoir! Watch our video on how to fill and prime the system here.
