Re: Solenoid part ? It's not a problem, I'm glad I could help. :) Most of the fittings used for CO2 are standard pneumatic fittings so any good hydraulics/pneumatics shop should sell them.

Re: Solenoid part ? Hose connectors are fairly easy to find. The thread will almost certainly be 1/8" BSPP and the hose fitting will be 6mm OD/4mm ID. At least that's the standard size for CO2 fittings. This a similar direct replacement and a sealing washer...

A single stage regulator has one regulating mechanism which reduces the cylinder pressure from around 55-60 bar to 1-2 bar in one stage. The needle valve then fine tunes the output flow. A dual stage regulator is easily recognisable because it's much larger and often appears to be two...

I would also contact JBL. It sounds like the low pressure gauge was overpressurised and has completely blown out. Replacing the gauge would be simple enough, but you need to know why the pressure got too high in the first place. If the reg has malfunctioned it won't be doing its job and using...

I might be repeating what Paul was saying because I'm not exactly sure where he meant the sealing washer should go. I'm sorry if this is the same information. The small cylindrical nylon tube (maybe about 6mm diameter x 3mm long) is for sealing between the reg and the solenoid, or between any...

I think a needle valve adjusts the flow rate at a given pressure, not the pressure itself. The UP atomiser requires higher pressure to force the gas through the ceramic; higher flow makes no difference because without enough pressure the gas still can't go anywhere. Andy's talking about being...

Your regulator shouldn't have any problem giving a high enough outlet pressure. I think 1 bar is approximately the same as 1 kg/cm2 so anything between 1.5 and 3 on your regulator will probably work.

I can't see an obvious adjustment handle on the ebay reg, but it's possible the knurled portion at the back is a handle. I don't have any experience with the TMC reg, but again, I can't see an obvious adjustment handle. The D-D regs, on the other hand, have easily adjustable output pressure...

Does the adaptor screw onto the regulator part of the way and then tighten/lock up before it's all the way on? If so, you've got the same problem I had. The reg and adaptor had the same standard thread, but the thread on the adaptor wasn't cut quite deep enough so the threads were locking up. I...

Thanks for the link, Hoggie. My problem is that I can't find anywhere to get the bottle refilled. :? I have BOC, Energas, Calor, and a couple of fire extinguisher places nearby. But the first three only rent out industrial bottles that are far too large, and the fire extinguisher places will...

I recently bought both the Boyu and the UP because I've heard good things about both and wanted to compare for myself. The UP looks a lot nicer and was easier to install because of the lock nuts, but I'm not actually sold on the build quality being better; the plastic seems quite brittle...

Thanks for the suggestion. Unfortunately all of the local Halfords' seem to have only disposable bottles, which are what I'm already using now. I go through one of those in about 2-3 weeks so I desperately need something bigger... just not too big. The ideal would be the 3kg bottles stocked by...

Thanks again for the help, that's basically what I thought. :) I live near Gainsborough and can get hold of fire extinguishers very easily, but I'd really prefer to use a "standard" gas bottle if possible. Trouble is, I'm having a lot of fun *insert sarcasm here* finding anywhere that has them...

Thanks for responding. :) With a fire extinguisher would the orientation of the bottle really matter? I've always understood the reason for standing a vapour-withdrawal bottle upright is to avoid releasing liquid CO2 into the regulator, but a fire extinguisher releases liquid CO2 anyway.

Silly question given how many people are successfully using FE's, but it's something I'm a little concerned about. Standard CO2 cylinders use vapour withdrawal, but because FE's use liquid withdrawal I worry that the regulator could be damaged or frozen if the liquid hasn't vapourised by the...

Unfortunately there's no adaptor (that I know of) to use standard disposable welding bottles on a Dennerle, but Dennerle do now make an adaptor to convert their disposable reg to FE/Refillable if that would be of any use to you. If you want to use standard disposables I'm fairly sure you'll need...

I was hoping someone who uses a disposable to refillable adapter could please help me by posting a picture of the adapter screwed onto the regulator. When I screw my adapter onto the regulator it only turns four or five times before it tightens up and won't go any further; the adapter is...

I didn't mean you didn't know that, Dave, I just meant maybe the person who told you got mixed up. :) If the Dennerle refillables ever used a non-standard thread it must have been a while ago, their CO2 lineup (BioLine/Comfort/Classic) has been the same for quite a few years now. They've only...

I've never heard of Dennerle's refillable bottles/regs being non-standard, but their disposable kits have a non-standard thread that won't fit regular disposable welding bottles. It's possible that's where the confusion came in.

I'm a big fan of push-fit connectors like the ANS splitter on Aqua Essentials. The connections are really secure provided you cut the tubing accurately and push the tube far enough in, but they're also really easy to disconnect if you need to change something. No more fighting to get tubing off...

Thanks for the links and suggestions, everyone. I'm not massively concerned about the cost of the reg, really; I just didn't want to spend £120 on the D-D kit when it comes with a lot of extras I don't need, and I can buy the same regulator from the OEM for a lot less. The running costs are...

At a glance Dennerle's bottles look just like any other disposable bottle with an external thread, but they have a non-standard thread size so only Dennerle's own bottles will fit on their regulators. It's a way to lock you into buying their products, which I don't want to do anymore - the...

If I'm not misunderstanding what you mean, I do only want one regulator. When I said "disposable reg" I just meant a regulator for standard disposable bottles. :) It's annoying that adaptors are available to make regs for disposable bottles fit a refillable bottle, but not the other way around...

Thanks for the suggestions, Bazz and Paul. The Dennerle reg is a Comfort Line for 600g bottles that I've had for years, so there isn't an adaptor like the one for the Nano reg. For a number of reasons I'd really prefer to stick with disposable bottles rather than an FE, but the difficulty is...

I'm tired of my Dennerle disposable regulator (you have my permission to laugh), both because of the expense of buying Dennerle's refills and because it has a bad habit of wildly fluctuating gas flow. It's definitely not set-and-forget. I've read about two stage regulators giving a much more...
