Larger sized Boston Valve with top cap for your inflatable.
These are the bigger versions that fit Jobe and Connelly tubes among others,
There is much confusion about which Boston valve to get so please take care when making your selection - if in doubt you can always purchase both and send one back for a refund.
These measure about 24mm to the outside of the thread on the Valve - if you are measuring the insert please allow for this - it will be less by the depth of the thread
These are the bigger of the Boston Valve and measure about 24mm total diameter - this equates to a 22mm inside diameter of your valve hole if you are measuring it without the Valve
Always a good idea to have a spare in your boat shed or garage in case you loose the one supplied with your Inflatable Ski tube.
Easy to fit - unscrew and refit this inflatable spare Valve
