<div dir="ltr">Thanks for the input guys.<div> My 02 bottles will be medical bottles that come already cleaned and be outside with 02 cleaned first stage regulators on them to go to LP right away and then I'll buy 02 cleaned LP hose to go to the SS threw hull fitting that's welded to the hull.</div><div> The sked 80 SS threw hull, 90 degree street ell and 1/4" turn stop valve weren't cleaned though so those should be easy to clean based on your input. I'll also go with factory 02 cleaned rubber hose to the flow meter so it would be just those three thing. </div><div>Just out of curiosity though, if a fire occurred from carbon/contamination or whatever, would the fire just burn very briefly in the hose and then go out or would there be an explosion that would rupture the hose? As I recall, the unfortunate fire that occurred at NASA in the capsule with the three astronauts, wasn't that a quick fire with no explosion? </div><div><br></div><div>Rick</div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Sun, Mar 12, 2017 at 7:49 AM, Sean T.

You need something with a high affinity for hydrocarbons which is residue free. Simple green and formula 409 are mentioned in the Oxygen Hacker's Companion, but I always use orange TKO. I use vinegar on regulator and valve parts to remove corrosion, and will scrub these after the vinegar soak, and then wash them with an orange TKO solution as the next step before rinsing with distilled or filtered water. Cylinders just get a hot orange TKO solution wash, followed by a clean water rinse.</p>
<p dir="ltr">I wouldn't use solvents for cleaning lines for oxygen service, although you can if you subsequently flush the lines to remove all traces of the solvent afterwards. A quick detergent solution flush, followed by a clean water rinse, followed by blowing out with clean dry air or nitrogen should suffice. I like to pull vacuum on everything I put together to ensure that any remaining water or volatiles are evaporated, but that may not be practical for everyone.</p>
<p dir="ltr">Note also that I only ever bother with this for 100 % oxygen service at high pressures. Most of the time, I assemble tubing and fittings as delivered, blow it out once with nitrogen to remove any loose particles, and call it a day.</p>
