8 threads are plenty (ie about 1/2 the diameter).... providing the engineers got it right, and the material and threading are within spec.... I still think the O-ring should be inboard of the threads, however....Bob
There is a thread on one of the other Forums that talks about a filter splitting lengthwise because it was made from pipe with a seam that was not up to the job....Bob
So it finally happened, I have warned people from buying cheap Chinese golden filters. It's just too risky if you can't hydro test them. I even volunteered to hydro one if someone would send me a sample.But it's fortunate that no fatalities on this incident. There are many of those things out there just waiting to explode. Don't cheap out on HPA equipment it's not worth it. I even hydroed one Alsafe carbon bottle before putting any air in it, I don't want to rely on Chinese manufacturers promise to keep my hobbies safe. Marko
how did the alsafe/liaoning bottle test ?I bought one recently for a project.
