Foreline backing pump & hose

[James_Ball]

I have a 50g tube coming next week. Just in time for getting the RV-3 pump running as foreline backing.

Should be a lifetime supply there. I just looked, mine is 25g and I have been using it for 20+ years now. It is about 3/4 used up but I would have more if I had not let a few others use it, who would squeeze out way too much when they did.

25g was $107 50g was another $30 so I figured why not. What sold me was reading that the silicon greases have a reputation for spreading away from their place of application. Further, the Apezion grease will stay put and actually scavenge trace volatiles.
