Some good points listed above, but I think there is some confusion over whats actually required. We are all talking about one-way valves, but whats actually required is a roll-over valve, which are commonly available ish and been used in circuit racing sine jesus was a lad

I believe they work by once rolled-over (past 90 degrees) the free ball-bearing (which is not spring loaded) inside blocks the exit, deemon tweeks have some, but I must say none of them look very "karting"

a real bargain at Ł278+Vat.....WTF......

am sure there is a 6mm push-fit plastic version out there somewhere for Ł2 including post, but where the hell is it!!!......anyone?

Hold on a mo.....Amazon might have just come up trumps, I think this is what everyone is looking for, used on bike fuel caps to prevent spill when rolled over, but allows breathing when upright:

Ł5.65 sounds far more karting!!!
