    I agree. I am sure o-rings are a thorn in the side for the manufactures too, and take up a lot of man-hours with inventory, sorting etc. with little or no profit. So why don't they just publish the sizes?  I would be OK if they said, we don't sell those we consider them a consumable and they are readable available from several third party sources, go to our web sight for list of o-rings for this model.

    FX has a diagram with o-ring sizes for every model. Here's the crown http://www.fxairguns.com/wp-content/uploads/2017/12/Fx-Crown-Exploded-drawing.pdf

    Be careful to only get the sizes for your caliber.

    Thanks for that, I have that list already. There are 22 O rings used in the gun with some duplicates. I will order a supply, but what is the abbreviation NBR mean. … I suspect  it means Buna material at a Durometer  "A" hardness of 70. Am I correct? Also in the case of say Figure and index number C2, the description states O ring 10 x 2. I assume that means 10mm OD x 2mm thickness. .Am I correct?

    No, it’s the ID and thickness. I use the O-ring Store, but the other suggestions are also good. And if I find the size I want in Viton 75 duro, I use that vice Buna-N. I’m always amazed by how many O-rings are in the FX gun’s compared to the simplicity of the Eastern European girls like the Crickets… I could totally strip down and replace every O-ring in my Cricket in 1/2 hour…

    How long does it take to strip down an Impact and replace every o-ring?

    I am having a similar discussion in another thread about the complexity of FX guns.  If FX guns are so great (and I believe they are when they work), why all there so many discussions about o-rings and elaborate guides to tear the Impact down?

    I’m still on track to get a Dreamline.  Hopefully I’ll spend more time shooting it than tinkering/repairing.

    Yes, it's the rubber hardness and as Centercut said ID x thickness.

     

    Edited for a typo.

    I don't know why you would want to replace every o-ring. There are just a few that would need to be replaced and probably every 5 to 10 years unless you mess with it a lot.

    The videos are there as a customer service so you won't spend money and lose time shipping for a simple fix.

    With a lifetime supply, what is the best way to store them so they don't go bad over time? i.e. should they be kept dry? or with a few drops of oil in the storage bag. Or am I just overthinking this?

    Silicone only petroleum based products no! keep them in a drawer they should outlast you. Dry should be fine or spray a little silicone on them either way.

    Thanks sonny.

    This is what Mr Rowe uses at FX USA https://www.amazon.com/gp/product/B0081JEBFC/ref=oh_aui_search_asin_title?ie=UTF8&psc=1 The big and small bottles are the same even though the big one says brake grease. An 8oz tube is probably a lifetime supply since it never dries or goes bad.

    O-rings don't last forever. I buy o-rings in 100 packs from McMaster-Carr as I go through them rapidly. The bags come with a "cure date" and either 10 or 15 yr. "shelf life". Fresh o-rings are smooth and shiny. As they age on the shelf they get duller and take on a matt finish appearance. O-rings removed from guns in the 10-15 year old range are hard and cracking.

    Are airgun manufacturers and dealers interested in profit? IMO the whole airgun industry would benefit if the market were saturated with o-ring size list charts for each model gun and its fill probe. Speaking of fill probes they should be readily available and super cheap. Japenese car and motorcycle manufacturers learned early on their cars would sell in the US market if parts were easily obtainable. Many airgun enthusiasts end up buying multiple airguns in various brands so trying to suppress repair knowledge and parts distribution just hurts the industry as a whole. I would guess Ernest's freely shared repair videos bolstered consumer confidence to purchase those documented airguns.

    Looks like you'll have to call FX or measure one that you have.
