- How to properly make a hydraulic hose assembly
Today we are going to review how to properly assemble a hose and explain why we do the things that we do when we are assembling a hose. First things first, we want to make sure to have a nicely cut piece of hose. We always want to make sure the edges are straight not curved, I recommended a straight blade or what is sometimes referred to as a wavy blade to get a good cut through the metal of the hose. You want both of the ends of the hose to be straight. The next thing we do once we cut the hose is we are going to shoot what they call projectile through the hose using a Production Facility Launcher. The projectile goes in at the top of the Launcher while the end of the hose gets put on top of a nozzle that is on the side of the Launcher. Using shop air the projectile goes in the nozzle, through the hose, and comes out the other side. Now this gets it to the ISO cleanliness level that is in the book, it’s through a system from one of our other distributors. So if you’re interested in any of these pieces of equipment we use today give RG Group a call, we’ll make sure you can get one. Typically what other people in the market will do is they’ll take just a normal air hose after they cut it, blow it out, and sell it to customers. While this is okay for some hoses there can still be dirt in there that is going to cause a lot of problems down the line in your system, depending on your pump and your cylinder.
So now what we want to do is couple the hose. Every manufacture is a little different, since we are a partner of Parker we use their coupling tools. For this video we didn’t have a depth gauge handy so we used the collar of the fitting, this is how we are going to judge how deep the fitting is going into the hose. So we put what we call a little “scribe line” on the hose that way when they are pushing it down we know how far to put the hose in so its deep enough not to blow off. You use a little bit of hose lube, which you can buy anywhere. You bring the hose down to where it sits on the line, and the reason you place the hose on the line is because below is what it’ll look like after it’s crimped, this is a safety measure that you should do to insure a perfectly coupled hose so make sure that you can still see your scribe line.
We have a -8 hose in the crimper so we have to use a -8 die. Every crimper is a little different so make sure to check your own guide. Inside the die cage is a depth to make sure that you’re resting on your ledge, this is a bottom out crimper so when it bottoms out you have the perfect crimp. Notice that you can see your scribe line still to insure this was put into the machine properly and crimped. Every piece of hose has crimp specifications when you check your crimp spec you use calipers on all 4 sides. You add them together and divide by 4 the average should be within 10 thousands of your crimp diameter and in this case it would be between .945 and .965 because we are using the -8 hose. The next thing we do is we wipe off the end of the hose to make for a hose that’s almost ready to go out the door.
There is one thing missing before the hose is completely finished, you want to make sure it’s capped. Why? Because if an uncapped hose goes into the back of somebody’s pick-up truck, rolls around in there, and then they go and put it into their system any number of things could have gotten inside the hose that now is going right into their system. So we use another machine that specifically caps hoses. This is a nifty little shrink wrap cover that slides right over top of your fitting and then you can push the hose in and the wrap shrinks down to form fit over your fitting. It’s not going to come off and now you have a perfectly sealed and capped hose assembly and you can do the exact same thing to the other end. There is a little strip on the cap that you can pull off whenever you are ready to use it. This is a step to step guide for complete clean hose assembly.
