Tear Aid Type A adhesive valve base. This is our enlarged adhesive base, the same we are using to make our stick - on valve. Easy to peel off as we added a small non-sticky section to the base.
The base is used for all bigger IN / OUT valves and one pump valves if you have a bad cut around the valve as it has larger area to cover / stick on.
Outer diametre: 120mm Inner diametre: 24mm - you can enlarge it to suit your valve hole diametre. Sold per piece.
