9mm inflate one way and 11mm deflate/dump valves
With ultra strong self adhesive base
If you need let say 4 inflate and 1 deflate with standard adhesive just choose 5 x inflate valves at discount price and leave me a message that you actually want 4 inflate and 1 deflate.
Standard self adhesive backing is 75mm in diameter. Go for standard self adhesive base if you able to remove the old valve without damaging bladder
Large self adhesive backing is 100mm in diameter. The large base will allow you to repare bladders with heavily damaged area around the valve.
1. Peel off by immersing your old valve to boiling water and gently peel off. If it doesn't work then cut the old valve.
2. Wipe area where valve will be sticked with alcohol pad (provided)
3. When the area is dry, peel of the paper backing and place valve on bladder
4. Press valve from center to outward gradually.
Other valves are available, see my other items on ebay.
