BOGERT AVIATION 90 DEGREE OIL QUICK DRAIN PROBE

Bogert Aviation 90 degree Oil Quick Drain Probe

The first big improvement is that the probe is leak proof. The AVI design could leak where it mates to the valve plunger making a mess. The new design incorporates an O-ring seal around the valve body preventing leaks. The O-ring also locks the probe to the valve body. The second improvement is the compactness of the probe. It is actually shorter than the BJ 107B making it easier to install.
