GW inner tube valve - black washer

No air leaks!

Constantly struggling with air losses in tyres? Apart from tyre punctures, it is often the area where tyres are attached to the inner tube that the air escapes through. If you get a GW valve washer, you eliminate the problem - it ensures maximum durability in the areas most vulnerable to air loss.

How to install it?

It is extremely simple - you can either use the cold-cure or hot treatment method. After installing it, place a rubber washer on the thread and tighten the GW valve.
