Those who use remotes with their paintball guns know what I'm talking about. We've all been there.

Remotes give us the unbridled freedom of a well balanced, air tank-free, weapon of mass paint destruction. But they also have the tendency to drive us crazy off field.

The plain old quick disconnect quickly gets old. Having to reach behind our backs to screw and unscrew the air supply, and to shoot down the remaining pressure inside the gun, is an annoyance to say the least.

Slide checks bust Orings like gangbusters, no matter how much we oil them, or sand smooth their surfaces. They work anywhere from a couple of hours, to a couple of months. Then to change the Orings out requires a complete disassembly of the quick disconnect, and slide check, to get to the Orings.

On/Off ball valves are a slight improvement. But they don't vent the pressurized gas from the gun, so you still have to shoot the gun down, before you can pop the quick disconnect off. I also had a problem with the little blue plastic levers on them breaking off, leaving me with an "always on" ball valve, which was worth next to nothing.

Someone on this forum (I'm sorry, I don't remember who), mentioned having used the Pro-Line Pro Adapters. I decided to check one out for myself, in my quest for hassle free remote utilization.

I picked one up at the great price of $25 from our friends at HotshotPaintball.



As you can see, the Pro-Line Pro is a complete replacement for the standard quick disconnect that comes with remotes. To install, unscrew the your existing quick disconnect parts, wrap a little teflon tape around the threads, and screw the new Pro-Line parts in. Altogether, the Pro-Line Pro is about two inches in length, from the gun, to the end of the remote. Thats shorter than the normal quick disconnect/slide check combination.

How does it work?

Inside the female piece is a spring tensioned valve that is normally in the closed position. No need to slide any moving parts. Just gas the remote up, and the valve is ready sealed.

Inserting the nipple into the female receiver, pushes the valve open, releasing gas into the gun. Now this requires more force than you're used to, but you'll get used to it. The nipple is long, so you have plenty of room in length, to "jam" the nipple forward into the receiver. Just make it a quick and sharp jab.

To release the nipple, just push the button. The gas from the gun will vent (out of the nipple itself), and the valve in the female receiver will close, as the nipple pops out. Hold on tight, because it will pop out fast.

The bonus? Remember how sometimes if your quick disconnect accidentally popped off the nipple, that little oring inside would be blown out and get lost? Will this won't happen anymore. There are no Orings to burst, or lose. And theres no mistaking whether or not the slide check is "on", or not.

Overall, this is one tough, well made, quick disconnect, that is the perfect replacement for anyone wanting to ditch their slide check.    

It might have been me. I know I'm obsessed with mine. Good review!

Someone asked me a question about attaching the Proline Adapter on a SpecialOps Paintball Dogleg Air-through Stock.

The base of the Proline Adapter is wider than a standard quick disconnect. In order to replace the quick disconnect nipple that comes with the Dogleg stock, I had to file a small piece off of the lip at the bottom of the stock.

The picture below gives a clearer view of this.

^^Sweet! Thanks for answering my question! And with pics...

Thats how a quick disconnect for a air compressor works i believe

That's how a standard pneumatic/hydraulic quick disconnect works. I've been using a miniature version of the ones carpet cleaners use. This looks like it would be infinitely simpler to apply and easier to use.

Mine has worked great for a while, but now it randomly disconnects. Any ideas?

One thing. There actually IS a tiny o-ring inside. Mine broke and I was never able to find another the right size, but these are, by far, the best Q/Ds out there.

Well back in the old days.............we would not have glorified that coupling by calling it a Proconnect. The Proconnect was actually developed by the Staubli Corporation. The difference was easy to tell. A true Proconnect actually had the word "paintball" engraved on the side of it. What you have there is still a Staubli connector (an RBE-03?) that was held in great disdain by true Proconnect owners.

But alas, along came N2/Compressed air, as well as low pressure, and the orifice size on the male part of the Proconnect was just too small to flow air fast enough. It also cost about 15 bucks more. And the great purveyors of cheap, National Paintball, hijacked the Proconnect name for the coupling you have.

The main complaint was that they did pop off every once in a while (CO2 is at the upper range of their pressure rating), but they are still vastly superior to anything else out there. If you play with a remote, they are the ONLY way to go.

I have one of these for my first A-5 and totally love it. I've had it for almost a year and would never consider using a slide check instead of this. It's never let me down.

Anyway, I just checked the Hotshot website to discover that they no longer carry this connector! They have something else called a Pro-line Proconnect, but the item pictured is not the connector that is reviewed here. I'm very very sad that I can't find another!
