Sticky button on Nauticam vacuum port.

My outer o-ring sometimes seeps a bit on the vacuum cap. The second seal on the button means it's not a problem, but because you never soak the button itself, it can get a little sticky sometimes. Is the Nauticam o-ring compatible with a little silicone lube? My button stuck in the last time I pulled the camera and I had to pry it out. I'll replace the outer o-ring before my next dive.

Hey Larry.

Sorry to hear that you have a small leak. Yeah, the o-ring is the typical nitrile butadiene type, silicone lube will be OK.

But it sounds like you have a small leak. Hopefully replacing the o-ring will stop it. My vacuum cap doesn't leak at all. And to help with the valve sticking, maybe removing it from the housing and giving it a good rinse in fresh water could help?

Good luck!
