Burst discs?

[Euphie]

Anyone know where I can get new Air America style burst discs? They seem to just be little pieces of metal held in by a nut, so I figure they probably have some industrial use, but I have no clue where to go about getting spares

You have an early "two piece" burst disc, that was made up of a hollow setscrew and a loose disc of brass or bronze. That's the way burst discs were back in the day (and not just in paintball) but there was an issue with people constantly overfilling CO2 tanks and blowing the discs.

And, instead of learning to properly fill the tanks so that didn't happen, they would stack two discs in there so that wouldn't happen.

That was, of course, extremely dangerous, so the industry went with what was called the "unified" burst disc. The disc is crimped to the end of the bolt, so you replace the whole works. And morons can't stack them to keep 'em from going off.

Just pull the disc you have and just swap it with a 'unified' of the appropriate pressure. Old style replacement discs are extremely hard to find these days.

Doc.

The burst discs are on the rail itself, are there any unified burst discs that don't stick up, or I am going to have to use half of the rail? The Apocalypse seems pretty sturdy, so maybe the rail would hold only using half of it?

All the unified discs I'm aware of, stick out of the port. The old versions like you're talking about, if they blow, while they save the tank, the single point makes the bottle spin off like a rocket. The Unified ones have cross vents to blow the air in two, four or six different directions, cancelling the impulse for it to go rocketing away.

I have a very limited few of the old separate discs in my collection, but they're all CO2, and either 1800 or 2200 rated. You need just a bit more than that.

The short rail might be your best bet. Ir try contacting the "new" Air America and see if they can set you up with a replacement.

I think I may have some of those old disks my old CP reg took them and CP gave me a extra bag of them when I had it serviced by them. Let me see if I can find it.

Edit: this what you are looking for? If so PM me your address. I got two of each I will send you.

Ducks: Those discs should be printed with a value- they have ratings just like the Unified ones. Was it a CP inline reg? I can't recall if CP made a tank reg.

If it was an inline reg disc, it's probably rated for 1800 psi. If it's a tank reg, it's rated for whatever the tank was. (4.5K for a 3K tank, etc.) The Apoc will need a 7K or 7.5K disc.

[Chuck E Ducky]

This was for a CP bottle reg. So standard 4.5k reg high and low. Not sure if that helps or not.

[DocsMachine]

If that's the case, they should work just fine. Are they stamped with numbers?

No one is thicker then the other so that’s the Hp one.
