hello fellow Impact owners..I seen you post on ordering bulk orings from oringsandmore.com and was hoping that you could help me out with a couple of questions….which orings are the right ones to order is it "Buna metric" when i click on item i don't see the NBR so don't know if I ordering the right ones also what about the little white orings"PUR" …..and just to confirm example 7.5×1.5 NBR 70 

1st # is inside Diameter 2nd # is Thickness 

And 3rd # is hardness any help would be greatly appreciated……Thank You

Sorry I am not recognizing these your cellphone screenshots, too much to scroll. Here are the Buna 70 and Buna 90 oring links from a PC:

- https://www.oringsandmore.com/metric-b90-orings

Hope these helps.

Pretty much comes to a point you will need to print out the BOM (bill of material) and go over one-by-one (with a highlighter pen) and decide yourself which orings you would want to replace to harder material or just to keep some spares in your drawers.

I ordered a full bag everything touching to a barrel/inside liner, and replaced all these NBR70 to NBR90, the main difference is the material hardness. The harder orings on barrel will "float" less in high heat and promises less shift to POI, but honestly I don't know yet how these will behave in deep freezing winter (me in Canada).

Just went thru the same. Ordered everything except the two or three PUR- PolyEurothane. Can’t source it anywhere, even oringsand more can’t point me to a place that carries them. Closest I found was Allieexpress, or go straight to FXUSA to get them, but I’ll hold out a bit longer.
