Hey Guys,

I know I've seen them before, but can't find them now...

Has anyone seen the stainless steel tube caps that snap/press fit into 1/2" or 3/4" tube? I want to use them to cap my my sightglasses.

Thanks,

Bryan
 
I'm sorry. I can't recall where you saw the tubing caps. You really do not want to seal the top of the sight glass tightly. It can create an airlock and not allow any fluid into the tube, like a diving bell.
