yam 3.6m sib valves

Hi, hoping that someone here can help. one of the tubes on my sib loses a small amount of air over about a week, I have traced this to the valve.

The valve has no name on it that I can see ,only the yam symbol on the cap.

It uses the bayonet type of valve addaptor for inflation , the type that pushes in and twists to lock in place.

questions are.
1. can it be unscrewed out with a suitable spanner to replace the valve ?

2. has this type of valve got a generic name? (I want to ask for the correct type)

3. any ideas who might sell bits needed ?

thanks in advance.

looked at the boat again today not sure if it is this valve.

If I unscrew the outer part to get a positive ID on the valve type, will the inner part stay in place ?. thanks.

Does your valve look like any of these : The yellow pin is the original patented HR, the other 2 are Asian copies, cost much less and works very well if maintained clean.

Need to perform a soappy water test on valve, to check if air leak is on outside or inside of valve. Will need a valve tool to remove outter valve body which is screwed on to tube fabric. In leak is from inside of valve, push and keep valve at open position, with small q tip dampened in alcohol try to wipe clean in circular motion the interior silicon seal, sometimes retains, sand, debris, whatever, and valve dosen't close tight.

Happy Boating

I will try the q-tip, if not I now have a valve spanner.


If I undo the valve with the spanner will the inner part stay in place ?.

Yes the spring will stay in place, if you valve has s small center middle screw, with a small phillips screwdriver hold upper pin and check if screw is tight seated on pin, sometimes the screw loosens with use. If removing upper air valve, must be screwed in the same position it was unscrewed so lower valve matches same marked position on tube's fabric. Try the Q tip first.

Happy Boating
