Learn how to service your valves and get them o2 compatible.
DISCLAIMER: Always adhere to the standard mixing safety protocols, and remember clean valves, tanks, regs etc. never guarantees a risk free environment. Always keep gasflows SLOW and keep the heat LOW.

I have a manifold from the 1960's that needs serviced so I can get operational for my classic twin 72's

@billhyatt3159 4 года назад

thanks very helpful only one note my manifold and valves are made buy Apex and they use an allen key (Hex drive.) the same size as is used for removing an A clamp adaptor insert, to remove the handles not a split flat bit screw driver took me a while to work this out!

Thank you for doing this video. Can you also do a dive cylinder oxygen cleaning video?

Good info...... Thanks..... But how long we need to clean the valve......

@erikfri898 3 года назад

beautiful video! if special hydrocarbon free detergent is not available then fairy or dishwasher powder or washing machine powder or similar household detergents do leave hydrocarbon traces on the metal parts? are not safe for 100% oxygen?

@danmirga Год назад

Thanks for the video! No problem leaving the burst disc on the valve during ultrasonic cleaning?

@lutfisken 5 лет назад

Perfect video!

@noanoa4283 4 года назад

Cool

@ozjohnno 2 года назад

looks great, but what about servicing the isolation valve between the first stages? Can you please do a video on that ?

@benbos1925 2 года назад

That is exactly the same as the other valves.

@hoyerdiving9974 4 года назад

Great video! Do you have a link for the airgun that connects to a regulator 1st stage? And for the 'split-screwdriver' tool used to open the knob retainer on the valve?

@benbos1925 4 года назад

Pathless where do you live? But find a “bestdivers” dealer they have that kind of stuff. Sesrch for valve tool. The airgun i made myself. Screwed in an inflator coupling into a normal lp airgun

@hoyerdiving9974 4 года назад

@@benbos1925 Thanks for the tip! I'm based in Denmark. Managed to find an airgun that will connect to my 1st stage, but haven't been able to track down one of these valve tools yet.

@benbos1925 4 года назад

Pathless nå en Dansker, prøv eventuel Bjarne fra Aquashoppen eller John fra Scansub eller Tommy fra scubagear.

19:12 on recreational cylinders, we see dive shops and manufactures suggesting crystal lune be applied to the valve threads before screwing into the dive cylinder. Is it common practice to omit the grease when performing an O2 cleaning or one of those debatable points of preferance?

@petrospapaioannou2036 3 года назад

What happens to the nylon part that is deep inside? Does it wear off?

@Beachgirl7654321 Год назад

At 16:08 when you're lubricating the o-rings on the stem, are you also lubricating the threads on the stem?

@DeGrigo_ 4 года назад

Thank you for this video. But very I missed how clean a tank. And in description maybe possible write all names this liquids and lubes?

@ew2ss 3 года назад

interesting too

@AHJKALKI 2 года назад

What's the two fang tool called ?

@papaalphaoscar5537 5 лет назад

Thanks for the vid. Just one question. Is this the actual way you O2 clean your valves or is this just for demonstration purposes? I'm now feeling a bit too anal the way I do mine. :-D

@MichaelWerle 3 года назад

I was thinking that as well.. going on about hydrocarbon free cleaning fluid, but no final inspection with UV lights, uses a paper towel (hydrocarbons!) to dry the components, and not wearing nitrile gloves when reassembling.. but again, maybe I've also been taught to be too anal when it comes to O2 clean.. after all it's mainly the outside parts that are being handled.

@gchqjtrig6492 5 лет назад

Would you wear clean plastic gloves during a real reassembly?

@marccollin7379 5 лет назад

for clean 02 you are supposing to use glove...

@poseidonswe 3 месяца назад

What if the valve is stuck to the steeltank with m25x2 thread?

@beachsandy1 Год назад

How to service spindle struck

@SeattleRingHunter 7 месяцев назад

Struck or stuck as in seized? Likely locked by unmanaged salt water that has seized. Have you tried soaking the valve in fresh water for a period of time?

@mikkosport2300 3 года назад

Oxygen clean, but... no nitrile gloves. Also is the plier oxyge clean? A lot of places to introduce hydrocarbons to the internal parts of the valve. Tainki into account that yhe internals should handle really high pressure O2! Not very professional.

@SeattleRingHunter 7 месяцев назад

I was quite concerned with the bare hands handling of the cleaned components. Let’s face it most bench air compressors used to air blast parts dry needs to be seriously considered as to what quality of air is being used. 😮
