Putting silicone grease on seals, and dowty seals when servicing your PCP Air Rifle'

[chaz]

As above really, I'm in the middle of changing the seals on my Daystate (FAC) Air Ranger in .25 Cal.

I've been told to replace the seals dry, by some, yet others say they last longer, and fit on more smoothly if I use a very small amount of silicone grease. 

I'd appreciate some constructive opinions/ experiences as to the better way forward. I'm more inclined to think a small amount of silicone grease would aid fitting and sealing??.

Cheers

I always use a very light smear of silicon grease on o rings ,did the same when diving for scuba gear and airguns for probably 30 year ‘ less is more .
