Okay. Silicone Grease is the only thing you should use.I followed your advice as well, beforehand of getting a new handle
No WD-40 should be allowed near rubber O-rings. Imagine WD-40 sucking into the vacuum cylinder and deteriorate the O-ring's prematurely.
You will loose vacuum pressure if the O-rings are bad.
