Building AN Hoses And Flaring Hardlines Isn't Withcraft, It Just Takes The Right Tools And A Little Practice

14. Expect a large amount of rubber debris left in the hose when you cut a hose with a hacksaw or a high-speed cutoff wheel. Depending on your application, this debris will go straight to your carburetor, engine bearings, or transmission. Using air to clean out the debris rarely does the job. Here I pulled a piece of paper towel through a hose with a wire.

15.Remove the tape before assembling the hose end. You’ll either never get the hose through the fitting or you’ll cause a serious leak if you leave on the tape.

16.Shoving the stainless braid into the socket end can be a bear if the braid has frayed too much. Those little wires will poke holes in your fingers in a hurry, so use a small screw driver or awl to coax the braid into the socket end.


17.Koul Tools has come out with a great new product that acts as a funnel to get all those steel finger pokers into the socket. It’s almost like a magic box for assembling braided hoses. XRP hose ends are smaller than others on the market, so Koul Tools ships a little disc to move the socket closer to the opening. I ended up wrapping a piece of tape around the socket to take up a little slack on the sides.

18.Clamp the Koul Tools composite tool into your vice. Confirm the socket is centered in the tool opening and wedge the end of the hose into the device. Turn the hose in a clockwise motion while pushing it into the tool. Within ten seconds the hose was all the way into the socket.

19.The hose end depth should be lined up with the insertion mark on the outside of the socket. The mark is just short of the depth of the threads inside of the socket. It’s also a tool used to determine the proper length to cut the hose for your application.

20.Tighten the nipple into the vice using aluminum vice jaws to safely hold it in place without damaging the finish. Put anti-seize lubricant on the threads and inside the hose to ease assembly. Be careful with anti-seize. It gets everywhere in a hurry.

21.Mark the hose end depth with tape or a permanent marker so you know if the hose pushes out during assembly. Tape can slip during assembly, so a permanent marker is a safer way to mark the hose.

22.Thread the hose and socket onto the nipple by hand as far as it will go to ensure you’re not cross-threading them. Be sure to push the hose with ample pressure while turning it to keep the hose from pushing out of the socket during assembly.

23.Use a wrench to finish tightening the assembly. If your wrench is damaged, there’s a good chance it will damage the anodized finish, so use a good one. You’re done tightening when there’s a gap of .030 or less between the socket and shoulder of the nipple.

24.By using the mark or tape on the hose, make sure the hose didn’t slip out of the socket during assembly. If it did slip, loosen the fitting and try again. If that doesn’t help, you may need to start over completely. For insurance, XRP suggests cleaning and then testing the hose at twice the maximum operating pressure. It should also be periodically checked for leaks under normal operating conditions.
