Burst disks???

[DiveGearExpress]

I just wish you would list them in the "Valves" section so they would be easy to find.

Always been there, under Service Parts....

The search box also works...

Does 9 you're fine, 10 you're mine apply to the DOT?

While you are correct, I have never seen them there before. I always just searched PRD.

Valves should be serviced no less often than the hydro schedule. Burst disc replacement occurs during valve service....

If you want to be pedantic, legally they MUST be replaced within 10 years of the manufacture date of the burst disc itself. Replace at hydro is easier to keep track of and for a part that cheap it's not worth tracking. Per CGA S-1.1

Really? can you cite this? We run a hydro facility and do 1000's of cylinders a year, been audited by the DOT and have never heard of nor seen in the CFR's for burst disc replacement requirement at hydro.

You're only doing hydro, you're not responsible for the valves....
Either way, I did cite it, it's in S-1.1 It is mentioned several times in there for each of the different types of valves.

Really? ..

Agree, In addition...valves are always removed prior to hydro at the dive shop. Valves don't travel with the tank to the hydro guys.

The theme of this thread is concern of the burst disk. The disk is in the valve. The 5 year tank hydro period is a convenient time to replace the disk as the valve is removed by the owner, LDS or in many cases the hydro facility who couldn't care less about the disk.

CGA S1.1 is not incorporated by reference in Title 49 CFR section 171.7 it has no force of law, but would be at best and industry recommendation Federal Register :: Request Access

Alright I see the requirement for PRD's but not a blanket replacement requirement. A CG1 type burst disc is not required for periodic replacement, i.e. such as SCUBA and most HP industrial gas cylinders. The requirement for leak test is required though at every filling. A CG7 type PRD does require periodic periodic replacement, e.g. Propane cyls such a forklift safeties S1.1 section 9
