Someone else may correct me, but I think that any oil will be good
enough for your application. That is I don't think you will notice
the difference between a 5 mm hg vacuum and a 5 micron hg vacuum for
degassing resins.

Hello, I have just bought a Welch 1402 second hand which I want to use
to degas silicone and urethane/resin.



2) what oil is acceptable to use I have some Robinair direct drive oil
and in a thread I researched somebody mentioned curt lesker and
company Tv-019 I want as good a vacuum as I can get without recking
the pump, but I am not sure I want to pay Welch Duo seal oil prices.



Any other advice/sources would be sincerely appreciated.
Thanks Steve
