custom 3 tank whip and low hours homefill unit

[Swim]

This whip already has a quick connect on it for homefills, so it will not require any homefill mods. As well it is designed to make your tanks stationary. This is made for working and filling at the same time, not for filling tanks, and disconnecting. There is a needle valve on the working end so that you can shut it off in between shifts easily. there are 1340 hours on the homefill, and it was bought right here on TMP from a person that sells them on the reg. The homefill will have the cover back on it when I ship it out. The gauge on the whip works, but the oil has leaked out, and you may want to remove it or replace it, but it works and I liked having it there. Also I would like to note that I never charge tanks over 1500 (if I even let them get that high) because I feel like it takes some life from your homefill, so this unit has not been abused. Considering the annoyance of shipping this, I may ask for references if I am not familiar with a buyer. Looking to get 300 OBO for the whip and 450 shipped for the homefill. THANX FOR READING

Oil??? In an oxygen gauge..?

So I've cleaned this up, not out of any favoritism, but because misinformation is as bad as no information, often worse. To re-cap the removed posts:

Swim posted his system (above) and some users expressed concern about an oil-filled pressure gauge and a heated conversation about the safety of oil near oxygen ensued. Adding oxygen to the fire, some members used it as an opportunity for name calling, insults, and other ToS breaking matters. The rest was a meta conversation about rules and actions of mods/admin.... I've left Mute's comment that started the whole thing, and below I attempt to calm everyone and add some context to the issue. Anyone interested can read on, but please consider this post the end of the oxygen safety discussion in this thread.

---------------------------------------

Oxygen is one of those things that I find most people who work with it don't really understand it.

Safety is another similar aspect of our industry. Most glass blowers I meet practice safety from a "I heard this once so I do it without question" and never really take the time to learn the ins-and-outs of anything.... monkey see, monkey do.

Most of the time that's as good approach to safety as any, as long as it's actually safe... and in this case, I'd agree that most of the people expressing concern are doing so from the right place - not wanting anyone to get hurt.

What is important is just because you don't understand things, and so don't do them, doesn't mean someone else with more information than you is wrong.


In the matter of oxygen pressure gauges, they are absolutely built in a specific fashion. To save cost most makers make all their gauges to the same design (oxygen safe), then calibrate and label them according to their intended gas... here's a semi-detailed look at the process: https://www.youtube.com/watch?v=-xF7d0nuFTw you'll see, gas never leaves the pressure tube to come in contact with anything external to that system, including the needle or anything it's in.

In any case, an oil filled sight glass on a gauge is perfectly fine for oxygen. Under normal use the oil (almost always silicone or mineral oil) (edit: or glycerine, as per the video, I guess...again not flammable) has absolutely no contact with the gas being measured. In the event of some failure in which the oil leaks out, it could, in theory, come in contact with high pressure oxygen. Mineral and Silicone oils are not flammable and have extremely high flash points, so they present relatively low risk of spontaneous combustion in a high oxygen environment.

I hope you guys learned something here, and we can allow swim to continue his sales post. As with anything you buy from our members the forum doesn't accept any liability or warrant the function or use of things sold here. Gas, particularly oxygen related, systems should always be inspected before use by someone knowledgeable in design and application of the target system. If you're not comfortable working with a material, don't.

Very nice.

Thanks for that Doug!

[Swim]

I received 12 lbs of greasy glass for this "unsafe" whip and homefill. HAHAHAHAHAHAHAHAHAHAHA , from greasy himself no less.

[Swim]

I apologize to the forum for my outbursts, but not to the people trolling my post without good info, I still think they should be castrated, thats just me.

[Mute]

Congrats.

Truth is I didn't know about the gauge issue. I honestly wasn't "trolling". At least not on purpose.

This is the second time I've been called names over this. I really don't appreciate it. Especially not from Doug.

Have a nice day

Nice Cleanup Doug...

Anyone know what size of fitting the home fill nip is?
I got a stainless braided hose that has a 3/8th" threaded and its not the same size as the homefill nip so I got to make an adapter.
