300 SERIES HOSE
Step 1 Bind the hose with a couple of turns of masking tape and mark the exact point at which the cut is to be made. Cut through the tape using a bench mounted shear, fine toothed electric cutting wheel, or fine toothed (24 tpi or finer) hacksaw. Remove the tape, clean up any loose strands of wire, and ensure that the Teflon liner has been cut through cleanly.
Step 2 Place both hose sockets onto the hose "back to back" (one end of the hose generally flares out, the other stays put - slip the sockets over the end that has stayed put). Using a suitable EXACT mandrel (XM series - found in the tools section), a pick, or a small screwdriver flare out or separate the Teflon liner from the stainless steel braid. Ensure that the Teflon liner will slip over the spigot of the hose fitting (the EXACT mandrel does this automatically during the flaring process) and remove the fitting.
Step 3 Place the correct - sized olive onto the Teflon liner making sure that none of the steel braids slip in between the olive and the liner. Push the olive onto the liner until the liner bottoms against the inner shoulder of the olive.
Step 4 Hold the fitting tightly in a vice (using soft jaws or a vice with surface ground jaws in order not to damage the fitting) and push the hose and olive onto the fittings spigot, making sure that it goes all the way home.
Step 5 Screw the collar onto the fitting by hand to begin with, and then, with the fitting mounted in the vice, with the correct size spanner. It is not necessary to screw the collar on all the way (although this is acceptable) - a gap of about 0.025" - 0.040" (0.65mm - 1.00mm) between the collar and the fitting is generally desirable. If assembling angled fittings or banjo fittings, check the alignment of the hose ends before tightening the final turn.
**Note - It is a good idea to pressure test all assemblies before use. EXACT can supply, or advise on construction of, a test rig for this purpose. Please remember to ensure the bore of the finished hose is free of any foreign matter before it is fitted. This is best done with an air line (dry air).
