Schrader Core Removal Tool Review - Appion VS Navac 

Hands-down, the best core remover tool is the field piece VC2G it has two valves one of them for your service port. It also does 5/16 and quarter inch and it also has a sight glass to see if you’ve actually got the core

Its 5/16 not 3/8. Thanks for the review wasnt a big fan of the Appion sucker leaked. Went back to old school C&D.

You keep saying that it’s a 3/8 it’s a 5/16

That's 5/16 not 3/8
