Oxygen Service 200bar Needle Valve 1/4" NPT
Handy little 200bar valve which can be used for throttling your oxygen supply on a transfill whip or similar. The chromed brass body/handle and PCTFE (Kel-F) seat mean you can feel slightly better about the choked flow of oxygen running through at sonic speeds. It’s not technically a needle valve in the sense of having a needle seat for ultra-fine and repeatable control for laboratory applications, but neither are most so-called “needle valves” out there and it will do the job no worries. The flow direction is reasonably important for proper operation, so make sure you select best option. Ships free (or at least, you only pay the maximum shipping once) with any of my other items, so why not check them out. WARNING: messing with high pressure oxygen can result in injury, death and/or generally vast amounts of damage to property and people. You need to be prepared to accept the risk, design and use your system properly and be aware of the consequences of failure.The "Oxygen Hacker's Companion" (see separate listing) is an excellent resource to help avoid blowing yourself up.
