Oiling Rotary Valve Tips

How to Oil Rotary Valves

Oiling Rotary Valves

It takes three different oils to properly oil the rotary valve mechanism.  Please note that the photos below show needle applicators but we now offer these oils only with a thin plastic tip.

Start with the Ultra-Pure Complete Rotary Valve Lube Kit.
