You don't get safety information provided on a sticker on any other pneumatic components. If I crank a cast iron fitting into a stainless steel tank to far the tank won't hold air anymore, but there is no warning for that. I have yet to buy a cylinder that came with documentation about anything. Everything is online if you want it. Clippard had installation instructions on the product page that specified the torque for fitting to seal the connection. When FIRST posted this:

Clippard recommends using 2-4 layers of Teflon tape and tightening the ¼” NPT fitting to 10-12 inch pounds (do not to exceed 15 inch pounds).

last year they didn't make it up, it came from the instructions Clippard provided.
