Valve

Hi All,

I wonder if any one can help me, I Need a replacement inflation valve for my 2.5m compass inflatable, as it slowly deflates. The Compass rep is extremely unhelpfull and rude.
Ive attached an image of the offending item.
Would be most gratefull of any help or advice.

Thanks.

I've got some Leafield valves for sale-measure the valve you've got and I'll see if I'v got one around the same dimensions.

Thanks for your help

The white plastic bit measures 27mm dia
The rubber seal measures 38mm dia
Total length when assembled 35mm

I have seen this valve on several boats that were labelled "Capri" here in Canada. The boats were made by Stomil in Poland. I have never been able to repair/rebuild this valve.

I have removed the parts like you have done, cleaned them, even added thin layers of rubber to the diaphragm (the rubber disc on the left) in an attempt to get a better seal with the body of the valve. Nothing worked, ever.

I suggest replacing the valve. I have done this two ways. First, and easiest, is to cover the existing valve opening and install the new valve in another location. Second way is to remove the glued in rubber base on the inside of the tube using a heat gun. You might have to modify the hole in the tube depending on the dimensions of the replacement valve.

Good advice (imo), these valves are going to be hard to come by, i believe the compass inflatables are made of hypalon too so replacing the valve with one of nos4r2's would be easier than a PVC equivalent, is there a round patch where the valve goes?

Dougg · 03 March 2007, 16:31

Yes the round patch is approx 150mm

The way to do it is to use a heat gun to get this patch off, you should then have access to the inside of the tube, you can place the cage section of the valve inside, glue a patch on and screw the valve in to the cage section....... i'm making this sound easy, if you neeed some more help on this PM me and i'll run you through it.

Hi - thanks for all the info here it's been very useful

I found that after being in unused storage for several years I had the same problem with the same boat............ but just cleaning and using silcone grease around and in the valve and lid seals seems to have solved the slow deflation problem for the boat to be perfectly serviceable (over night and several days at high pressure)

It's usually stored deflated in a locker as I used it as a shore tender only when cruising - this simple fix seems to have solved the problem for me, hope it helps someone else

all best
