Cheap Check Valve for Direct Butane Injection

Unread postAuthor: saladtossser » Sun Jun 26, 2005 8:43 am

it is not for venting, but for spraying butane in easily and it is self sealing right after u remove the butane.

edit: u move the magnet out of the way and back when done.

good, but you need some gasket material around the hole to give it an extra good seal

A metal flap, so simple. The inner pressure will just push it harder against the wall of the chamber.

Pick up some of those neodymium magnets if you can, that's pretty much the only kind that will stick that hard.
