I have never tried silicon tubing with it as all my connections are petrol proof as it can be contaminated from outsides as well as internally, I don't know the manufacture of the mould oil I have as it was given to me by a chap on one of the building sites I have to visit occasionally, so I am afraid I can't be any more help than that, if I can find out what manufacture it came from I will post it on here.
