Leaky Inflatable Boat Valves

[Fog Ducker]

Hi, I have an inflatable boat that I use as a tender for my Sirius 21. I bought the inflatable used, its an Air Concept, the problem is the valves leak air around the threads when they are in the boat. they are quite difficult to screw in, and take out of the boat. If I use a pair of Channel Lock pliers to put them in they wont leak, but in other inflatables I've had in the past you could just put the valves in hand tight and they wouldn't leak. Do any of you guys know of anything that I can put on the valve threads to make them easier to put in and take out, and to stop the leak.

The gasket should make the seal, not the threads, so the real answer is probably a new gasket.

If you want something to put on the threads, you might try this - https://www.escopro.com/dow-corning...MI_vGY56qS3QIVD9vACh0OSA94EAQYBSABEgIhdPD_BwE

It is both a lubricant & a sealant. It is the material that Luxfer recommends specifically for use on the O-rings that seal the valve to the neck on the scuba tanks that they make.

I agree, the gasket, a.k.a., gland, may be weak or worn.

A good product for lubricating valves on inflatables is 303 Aerospace Protectant, as it contains no silicone (which would render glue repairs impossible).

The best site and supplier I have found for inflatable repair knowledge and supplies is NRS:

I found on my inflatable, if there was any sand in the threads I could not get it tight enough to seal. As others have said grease or new gaskets can help too if your treads are absolutely clean. Hope this helps. Happy sailing.

I had all of the valves replaced on my Achilles 8 1/2' hypalon inflatable last year. Plus, a couple of leaks were repaired. That boat was bought in 2000 and has been used a lot--still in good condition. So, it has been worth it not to have to fuss with leaky, worn out valves! Dinghy stays inflated!!

If you want to try new valves (which I assume would come with new gaskets), I have had good luck with these folks:
