Making PEX Connections
Dan: Hi, I’m Dan. Welcome to Watts Workshop. I’m here with Steve. And we are going to learn how to make PEX connections.
Steve: Hi Dan.
Dan: Steve, what do we have here?
Steve: Yes, today I brought with me pre-cut lengths of half inch PEX pipe, some brass PEX fittings, some plastic PEX fittings, stainless steel cinch clamps, copper crimp rings and quick connect fittings.
Dan: What’s so special about these guys?
Steve: Dan, this fittings are designed specifically for useful PEX pipe to make a nice tight clean connection.
Dan: Okay let’s get started.
Steve: Okay Dan, first one we’re going to do is the copper crimp ring
Copper Crimp Ring
Steve: We’ll need a couple of things, you’ll need PEX pipe, brass or plastic PEX fittings either one is fine. Its personal preference, copper crimp rings with good quality crimp ring tool, a nice sharp tubing cutter and a Go-No Go Gauge that comes with the tool, so let’s get started First thing you want to do is take your pipe, and make sure that you’ve got a nice clean square cut on the pipe. Next you want to take your copper crimp ring and slide it over the pipe and you get a nice tight fit on the pipe. Take your fitting, insert it completely into the pipe to the shoulder of the fitting and then push the fitting back towards the shoulder to within a quarter of an 8 of an inch of the shoulder. I’m going to ask you to hold that. At this point when you take your crimp ring tool, open it completely and seed it around the copper crimp ring squarely. And you may have to move that crimp ring back just a little bit to get it close to the shoulder. Squeeze it all the way through, open it back up and your crimp ring connection is complete.
Dan: Steve, you mentioned the Go-No Go Gauge. Can you explain that again?
Steve: Sure Dan. The Go-No Go Gauge is just a tool to make sure that you’ve done a correct grip. You’ll look for the half inch portion of the tool and there’ll be a no go section and a go section. And what you want to do on each of your crimp is to check the no go sign should not go onto the fitting and the go sign should go onto the fitting completely. That’s how you know whether you made a good connection. If either one of them don’t work, you have to cut the connection out and redo it.
Stainless Steel Cinch Clamp
Steve: We’re going to start with our PEX pipe, our brass or plastic fittings, instead of crimp rings, this time, we’re going to use stainless steel cinch clamps, our tubing cutter and our two types of cinch clamp tool. One is a one handled tool; one is a two handled racket and I will explain how both are used. So we’ll start with our PEX pipe. Make sure that it is cut nice and square. Take the cinch clamp, put it over the pipe, and insert the fitting. Now the nice thing about the one handled cinch clamp tool is that it is just that one hand and it allows you to maneuver the cinch clamp and place it on the pipe. So you insert your cinch clamp. Use the tool; push down on the tool until it can’t go any further and then finally, with trigger on the side of the tool, you release the tool and your cinch is done. Now the other type of tool is the two handled. It’s a little bit more difficult to use because you have got to use both hands if you won’t have the ability to do maneuver that cinch clamp so you have to use the tool to do it. We will start with our pipe. Make sure that it is cut square. Take the cinch clamp. Place it over the pipe and start the fitting. Now this one I’m going to have you hold. Open the racket tool completely; insert the ear of the cinch clamp and you may have to wiggle this just a bit to get it into position, once it’s in position, go all the way through with the tool and the tool will release itself when the cinch is done.
Steve: All finished.
Brass and Plastic Quick-Connect
Steve: Alright Dan, let’s move on to quick connect fittings this is the easiest method to join PEX pipe but its also useful for joining copper and CPVC as well. We’ll start with our PEX pipe and our quick-connect fitting with our PEX pipe insert, our sharp cutters and a pencil. So the first thing that we want to do is take our pipe, make sure that we have a good clean square cut using the measurement guide on the fitting. Mark a line from the outside of the fitting to the line, take your PEX pipe insert, place it into the pipe, and then insert the pipe into the fitting until you’d reach that line. That’s the connection.
Dan: That’s it?
Steve: That’s it.
Dan: Steve thanks again for showing us the three basic types of PEX Connections. Before these are any further advice you could give us?
Steve: Well Dan, few things; one like anything, it takes a while to get used to making these connections so I highly recommend that the user try one of each or a few of each connections so that they could get used to how the connections are actually made. Secondly, even though PEX is widely approved in North America for plumbing service, I’d still recommend that you check with your local code authority to make sure it’s approved in your area and lastly, before you seal any fitting up in a wall make sure that you run your leak check with either air or water to make sure there are no leaks. If there are leaks, disconnect the fitting or cut the fitting out and redo the job.
