Blower Oil Level Sight Glass
At RBS we have found this to be a truly handy device. With this oil sight gauge installed on the front of your supercharger you can be assured that there is oil in the front of your gear case.
This unit is black anodized alum. with a clear site glass and uses a O-ring to seal. Threads are 1/2-20" and simple to install on any roots blower.
