preset blow burst disc

[Skeet]

Hmmm....HPA burst discs arent two peice liek teh Co2 ones...they are a complete unit....they have a hole at teh top, from which air will escape, if teh burst disc at the bottom, fails. I think they are made of Nickel or something, teh actual discs, theya rent copper I dont think....

both my 7500psi and 1800psi appear to have holes through them

youve got the nut bit at the top, then under this youve got a cylinder secion wiht the PSI rating, its this bit thats got the hole. then it steps into a smaller cylinder and goes into the preset. both of them look identical....?

ps, im a bit of a noob

Can you take a pic.
