Daniel Hogan, one of founding partners has always stated that the end consumer doesn’t know the results of the quality of the hydro-test, they only see the stamp on the bottle. That being said, it stands to reason that a company that doesn’t spend much time or effort to properly label your tank after testing may not have put much effort into testing it. Here at paintball hydro we understand that paintball tanks are exposed to PEG (the fill of a paintball), sunlight, moisture, and generally being tossed into gear bags or rubbed on the ground. To combat these issues, we make sure to overcoat our hydro labels with a solid coat of high grade epoxy to make sure they stay on.
We test the integrity of the threads on each bottle with a no-go gauge to ensure the threads are deep enough for the valve not to blow off. Ninja paintball is the only other company that we know of that does this, probably because they know something about the bottles they sell. Paintball players who fly frequently with their bottles take the valves on and off for the TSA should be especially concerned with this issue. Most players only have their valve off every five years for testing, and it’s less of a concern. Pro players who have had the valve removed and reinstalled several times usually sell off their old bottles and there are lots of used bottles out there.
Fiber wrapped bottles take time and patience to test properly. We love this sport and we wouldn’t speed our way through a test because the fiber wrapped bottles take longer to test than a solid aluminum or steel tank. We understand the consequences of a bottle failing out in the real world while someone is holding it.
Hydro tests cost about the same everywhere, so it makes sense to go with a company that you trust and who understands what paintball cylinders go through in their lifespan. Check out their website, talk to someone who works there, and go with a company you trust.
