Cork pop guns

I've made a few cork pop guns using a PCV pipe and a dowel with an O ring to
ensure a tight fit. But I need advise as to the proper lubricant to prevent
the thing from sticking.
Vaseline and KY Jelly work fine for a while but soon lose their
effectiveness.

I thank you for your help.

I wonder how long it will take this thread to go off topic? Whoops! I
think it just did!

PS How can the people in Kentucky eat that stuff?

Have you tried using a cork instead of dowel with an o-ring?
That seems to work well. Wine bottles are not sealed with o-rings.
Or try one of the new plastic corks?

Try Dow Corning 111 silicon grease

Works for YEARS to lubricate orings in scuba gear, but probably should
be re-lubed yearly

Petroleum based lubricants will break down or break down the rubber
O-ring. Try silicon lubricants. They last longer without decomposing.
You should be able to get silicon based grease at any auto parts
outlet.

It has a little bit to do with how tight the O-ring fits the pipe.
Try machining down the groove that holds the O-ring, than if you get
too much leakage, try a second O-ring, in parallel to the first.

And use silicone grease.

Make sense?
