O rings installation tool

nylon dental type tools/picks work great but some of them are weak, so a set of metal ones is good. You can get them at Amazon, harbor freight, or dentalsuppy stores.

Regulators?

Witches hat, dental examples shown below.

For the extremely small O-rings, like those found in FX regulators, I have made several different witches hats. A witches hat can be made from something available like an ink pen barrel tip or you could order a kit from Bagnall & Kirkwood that includes the necessary O-rings to rebuild an FX regulator.

Yup, before I found those.... actually, I was just too cheap and in a hurry..



Yes, it is part of pen. And that's a part of a regulator.

Softer brass tool/picks! Steel will scratch the reg and cause leaks and creeping. Most of the nylon picks are too soft, IMO.

Still not the easiest thing to do but when in a pinch, it will get it done.

I like quality and specialty micro tools, actually all my tools are in higher scale starting from my garage and all the way to my basement mans cave.
Couple years ago I picked up a nice "nylon dental type tools/picks" set in a Trade Show, from orings supplier stand.
I never needed more so I never ordered any extra from them, but I would assume any dedicated orings suppliers may have tools solutions for you if you ask them.

How cool is that. I'm a retired dental rep. and I have a set of those O ring tools. Mine came from RPI a couple decades ago. They are somewhat proud of the darn things. Back when I was with a dental manufacturer we made those tools in our machine shop for miniature valve assembly. Can likely find similar or Amazon and Ebay W/O paying the "dental tax" be sure to use O ring lube on the tool, I like Parker Super O lube, it is Silicone based, good stuff. Firewalker, you are Minn i dam sota We may know each other...or have mutual friends.

No luck on Amazon
But there are a number of sellers on eBay
With prices varying very widely
Here is a link



Hope this helps

Yup nothing much on Amazon. The small ones from DCI on ebay are pretty reasonable tho prices vary like crazy. You can get the retail pricing @ dcionline.com prolly 59.95 for the three tool set. That's the dental tax I mentioned earlier, Dentistry is never cheap, neither is the stuff for dentistry. I recall paying about 50 bucks for my set I bought thirty years ago from RPI another dental parts vendor.
I did see some Polycarbonate picks on Amazon that looked very useful. The tools are great when you have parts with multiple O-ring grooves.

brilliant!

I love it when we can fabricate a useful tool. The dental tools detailed are quite small, the largest of the three is useful for our stuff mostly. I did see Polycarbonate picks on Amazon, they also had brass picks for removal.

Wouldn't something like this work cut to fit?


Or these:

Good thinkin! You will need to be cautious to not overstretch the O-ring. Great idea!! Lots of different sizes available tho it may take a little looking around. Heck as costly as the tools are, one could buy and throw away the product just to get the right size "spout" Put a light film of Super O lube or Silicone paste lube on the tool prior to use.
Mostly the O-ring tools like this are useful for items with multiple O-rings on the valve stem. They are equally useful for the little tiny guys. Much easier to handle that way.

did you heat the pen tube?

@Ricklin , The white jewelry tools are ear hole stretchers and come in measurable sizes. Plus they are cheap. I never knew such a thing existed until I saw these by accident. "ear stretchers" are not something I would run into on my normal daily jaunts.

Awesome, I really liked the idea of the spout, pretty darn cool and practically free...a very good price.
