Lubing your Impact

I don't have one, but it seems like Silicone grease might work well. I use it a lot in construction for sliding doors. Easy wipe off, clear, doesn't collect dirt excessively, and is am excellent lubricant

Anywhere rubber or plastic rubs against something, silicone makes a good choice. However like you said, any wet lube will grab and hold onto potentially abrasive debris carried by the wind and such so it may be a net negative in, say, a windy desert (sandy) environment. In most cases however I would say its fine.

Meanwhile silicone is a terrible lubricant for metal-on-metal so use something else there. Dry lubes like molybdenum disulfide powder, tungsten disulfide powder, or even simply graphite burnished onto the metal surfaces do great in most cases. The upsides being of course that they don’t trap debris but also don’t cause temperature-related issues like wet lubes which change viscosity. Just bear in mind these dry lubes don’t work so well with aluminum so you may find a wet lube is necessary in some cases.

I was going to say the same thing... If you make the metal on metal mistake with silicone one time and you’ll never do it again! Might as well weld the pieces together!

Have a great day. Stoti

Yes if you need a wet lube for metal on metal, a moly-based grease is fine. Frankly most anything but silicone...we have no high speeds, high load, or high temperature challenges that lubricants are often called upon to handle.

nervoustrig is on tract here. I would add that a lubricant with PTFE (Polytetrafluoroethylene) applied and wiped close to a dry layer will provide all the needed friction lubrication you need for current air gun tolerances.

I'm in agreement with nervoustrig as well. Anything moly based for metal on metal.

The top and bottom of the Impact cocking block has 4 little plastic pucks that the block slides on. Shouldn't need any lube as the Delrin pucks are slick and incredibly tough.. Replacement pucks are a specialty item and expensive (I lost a couple), but can be purchased from FX.

As for lube, less is better. Lube attracts dirt, so I only lube where absolutely needed. Recommend that you not lube the cocking block as the pucks serve that purpose.

Aint hatsan blitz high speed I that thing lets off 45 rounds in 2 seconds?, I read somewhere moly is bad for fast moving parts like bearings.
