    Bsa spitfire pressure indicator seal/ flat seal?

    I have a spitfire and one of the seals has gone and it's a bit of a odd one, it's a flat seal not a o ring and don't even know what to call it to try and get another! Pics below of said seal.



    It looks to be 9x3x3mm
    It's the one off the fill level probe so it was easy to get out.
    Any ideas as to what to call it or wether one could be made up? It's annoyingly just a shade bigger than a co2 bulb seal which would have been perfect if a bit thicker.

    Looks like polyurethane. Easy to make, if you have not got a lathe it can be punched out of polyurethane sheet using hollow leather punches. You could also try John Bowkett who designed these and has parts. I buy sheets and rod off the horrible bay.

    I think I can make one of these. I have a set of punches and some sheet.
    PM me your address and I will send you what I produce.

    When I make these on the lathe you automatically get the hole concentric with the outside diameter. Using punches takes more skill or a bit of ingenuity.
