Q:

Drilling into Clylinders…Catalinas Official Response

I thought I would go straight authorities in HPA tanks to answer this question. Catalina Cylinders.

Here is the email correspondence about the matter:

Subject: Question…

I have a question. I read on a airgun forum of a person drilling and threading a hole into the bottom of a 490cc 3000psi tank and installing a gauge to read the pressure inside the tank. He has been warned this is not safe.

Could you please give your position on this so it can be relayed to others who might attempt this modification.

Thank You,

Adam Vigil

This is an unacceptable practice and can be very dangerous. Catalina Cylinders in no way, supports such an action. Any cylinder that has been altered in this way, should never be charged again and pulled from service.

I just drilled and tapped my dads 5000 PSI main nitrogen cylinder for another valve. In hopes that I could charge two smaller pressure testing bottles at once.

…JOKING!

Thank you Adam for posting this.
Here’s hoping the warnings are heeded.
Walter….

Well, they would say that, even if they knew, technically, there wasn’t that much risk in it.

I still wouldn’t have one up against my cheek though. Food that’s a few days past it’s sell-by date is one thing… 😆
