MVHR O ring seals - lubricant?

[Sparrowhawk]

The assembly pictograms that come with the ducting and seals show some kind of liquid being dripped onto them.

 

Nowhere does it specify what it is.

 

Have you done this and if so what did you use?

Silicone, same stuff I use to fit push-fit drainage.

I just used silicone lube. Similar to the link, but way smaller, that size if you want it to last a few lifetimes.

That would work.

Went for silicone grease in the end and it made the task a piece of piss.

 

Thanks for your help!
