Has anybody ever wonder why the HiPac was not designed to screw directly to the valve replacing the back end of the valve. And a better question is why isn't there anybody on the forum making them for us Canadians, instead of having to get them from the US.?

So that you can go back to CO2 without changing the gun, and so that no disassembly is required?....

No Canadian is making them as there is zero profit in the venture.

Ok so not much profit in making them for sale. As far as attaching one directly to the valve. Is there any danger to doing so ?

Walter... succinctly put.

Joe...threading a similar device directly into the valve does not provide any safety issues...providing the device itself poses none.:rolleyes:

The big advantage I can see would be eliminating that tiny hole between the HiPac and the valve which limits the air available for the shot to the volume of the valve itself.... More power would be available, but likely fewer shots if you took advantage of that....

Yeah, the plug-n-play simplicity as it is provides the majority of HiPAC owners with all they want. For the rest of us who want to modify stuff it offers some nice improvements over CO2, and with a bit of tweaking of the valve or the new stainless steel high flow valve from the same guy, there really doesn't seem a need to change it fundamentally. And of course some will appreciate the utility of going back to CO2 if there isn't a pump handy. I can't stand CO2 so not for me, but I see loads of 12g cartridge fans in this forum so mine is probably a minority opinion.

As for the cost, I got mine a couple of weeks ago and have to say it seems a great deal. Better workmanship than that put into my Brocock Atomic to be sure. And since I already have the Gehmann pump for my Pardini and Brocock there's no added cost for filling; it'll pay for itself in saved CO2 within a few months. For some reason there seems to be a lot of doubt on various sites regarding HiPAC reliability, but it seems to me the maker has a solid product, and he's very responsive in his network54 dedicated forum.

Perhaps an optional model for direct attachment to the valve might be a better solution. The manufacture of such a device would be much easier and faster to make. Time is money, they say. Also there would be no need for special seats, that still need replacing occasionally. Since the 22xx series guns are so accurate, a permanent conversion to PCP makes sense, at a fraction of the price of currently available PCP rifles.
the concept would certainly appeal to enough shooter's to make it worth while.

I can't think of any good reason this couldn't be done. Sounds like a good idea to me. If only I could turn the thread to engage in the end of the tube I'd give it a go. Although, since it's threaded into the valve, maybe it shouldn't engage the threads in the tube as well - you'd never get both to tighten at the same point. You would need to secure it somehow. The front frame screw could be one point, ok for low pressure fills. Add extra screws for high pressure?

No need for threads at the front, and since the pressure is all internal within the valve/conversion unit no real need to anchor it with more than the stock valve screw, IMO.... Some way to prevent it from being unscrewed from the valve while under pressure would be a good safety idea, though....

I'm with Bob on this one..no need to pin the valve in this scenario. Would use a hole to bleed off pressure IF someone puts a big enough wrench on it to unscrew it while under pressure. Similar to regulators, and co2 valves on bottles...or a qb78.

That would be the simplest solution, Al, and a good one.... I would suggest that since you have to take the valve out of the gun to fit it (the first time) there is no reason to have any flats/etc. on it to tighten it more than hand tight.... A piece of 3/4" tube, turned down to fit inside the 22XX tube, two threaded end plugs sealed with O-rings, the front one with Foster fitting, and with the one at the back having a groove to miss the trigger screw and internal threads and O-ring seat to attach to the valve and it's done.... Not that cheap to make, though, with all that threading.... but could be any length.... Unless you put a joiner in the tube to step up the diameter, it would be smaller volume than the same length 22XX tube, of course, because it has to fit inside.... That step up means 4 more threading operations and 2 more O-rings, a joiner, and double the cost.... unless you can do pressure rated welding....

At what point do you just say the heck with it, buy a 2260 tube and a Disco valve and fill fitting?.... especially in Canada where if the tube is a 2240 or 2250 it remains a pistol so has to stay under 500 fps.... That makes a pretty limited market this side of the border, IMO....

X 3. Unless it was something special that I was going to build for myself. But as for a client, its not cost effective....IMHO.

It looks to me that the front half of the hipac is currently made of a solid piece of steel, milled and threaded. I don't know anything about machining didn't realize cutting threads was such an expensive and time consuming undertaking. As for buying a disco tube and valve instead ? I did just that and the cost was more than tripple of my hipac and 3 extensions.It is why I'm looking into this idea. Because now I have a hipac with 3 extensions that I want to use, but I want to make it seal better.
with the help from you fellows, I may take a different approach, but need further assistance. What I was wondering is this. If I fine thread the nipple on the hipac, and drill and thread the end of the valve, would there be enough threads to safely hold the pressure. Since the diameter of the joint would be small, 5/16" or there abouts, and approximately 3/8" long. Would that be adequate to withstand 2k pressure ? I think it should be as it is about the same size as the threaded fitting on the hill pump hose. Maybe a little smaller in diameter, but longer.And thats good for over 3k pressure.
