OS Series Valve Assembly with Extension Hose, for Use with CT2511 CleanTex Microduster III, or CT2512 and CT2513 CleanTex Refills (CT2505)

We do ultra-trace chemical analysis: this leaves very little residue. But I've been buying the metal valve/disposable can version for years, spending many $100's. Conclusion: (a) metal valves don't last long (b) 5 out of 15 valves were defective, leaked & caused frostbite while connecting, and dumped the entire can in one go. Others leaked over time, lost 15 cans so far. Some of my staff are not strong enough to change the can (clip is too tight... but has to be in order for it to work). The metal valves versions are thus FAR MORE EXPENSIVE and far less usable than this disposable valve version Clean Tex 2510.

It just works. You need clean air blown at something--this is it.

I purchased the replacement valve assembly. I used it a few times and the valve began to leak. And then it would let all the air out of the can within a day. I lost several full cans because of this. Very bad!
