*** IN STOCK SHIPS TODAY *** Many of races have been lost and catastrophic engine failure caused due to a race transmission having no or low air pressure causing incorrect gear or no gear changes to happen during a run.
With this little fitting it simply installs in the racers air bottle with an Allen wrench and provides a double O-ring seal at the air bottle valve. Don't trust a plastic washer to seal that can crack or break treat yourself to one of these and be done with it.
Check your air bottle that it has internal threads on the valve as most due but better to be sure.
Works with all Lenco and B&J air bottles.
