Bsa spitfire pressure indicator seal/ flat seal?

[rovercoupe]

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.

That would be amazing, I will get some proper measurements and give you a pm.

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.

It crossed my mind but there way too soft.

[Benelli B76]

Probably about 90 to 95 Shore A polyurethane.

Well Christmas came early thanks to neil54 sending me a few made up seals to try and got one fitted yesterday and it held air and as we speak is still holding with no leaks.

Big thanks to Neil and everyone on here for the help and keeping another rifle working.
Merry Christmas!

My Spitfire is a cracking compact carbine and makes a great 30yd Squirrel gun but it's started loosing air over the day if left but can't find where it's leaking for love nor money

John Bowkett, the designer, says there is a Teflon seal that needs to move on a regular basis or it can start to leak. Sometimes if the rifle is unused for a long period you will get a leak. John says this seal should be custom fitted to the rifle. People often replace this seal with other types of seal. The leak will stop, but you can get erratic fps results for a few shots each time you start using the rifle.
