FX Most commonly replaced O-rings on an FX Impact M3

The 9 that all have to do with rear plenum, and the 6 that all belong to the reg 2 area. If yours is an M3 get the ones for the reg 1 area as well. These three areas are typically the first to start leaking.

It would be wise to also stock up on the bottle o rings, all o rings tied to the barrel, gage x rings, and 12mm Dowty seals.

The o rings inside the cocking block parts, those rarely fail

I have a full oring set for my MK2 purchased from orinsandmore, each size a small bag of 25.
Every time I take my Impact apart I replace the oring which was removed.
The most part numbers I spent were the breach oring and the 2mm on the Valve Rod end (for a known reason).
After many years of playing with my Impact I think I settled with a setup so the remaining orings are in safe number :)

If you need a full list of the O-Rings, it's on an Excel spreadsheet here. oringsand more part numbers are included, in most cases.

Thank for your excel sheet... I order from local online store in my country with Very cheap price.. But if I order from the fx retailer in Indonesia the price will be 500% up..
Btw I can't find x ring in my local online stores... Any idea what is x ring? I just give the store the spread sheet but they don't have the x ring... The other orings are available with cheap price...
 
Metric X rings look something like this and are normally the seals for the gauges....
