Then, place the collar and hose into a vice and lubricate your fitting. This is the difficult part, as getting the stems to line up isn't easy. That said, if you're really forcing it, you're likely doing it wrong and should start again. Begin tightening the fitting inside the collar and keep going until you approach the point where they're within touching distance. At this point, do NOT tighten any further. Having these two pieces touching is over-tightened and can lead to leaks and breakages, leave a small gap for safety.With that, you've got your hydraulic hose fitting installed securely and ready for work. It's not a big nor difficult job, but getting it right is crucial to ensuring that your machine works correctly the next time it's fired up. That's why we've decided to put together this brief guide on how to fit a reusable hose fitting safely and correctly.That's the case with hydraulic hose fittings, which are integral to the successful operation of millions of machines around the globe. If fitted incorrectly, these fittings can leak, disconnect or (in the most extreme cases) snap off entirely. First, get your length of hydraulic hose and hose cutter. There's a good chance that the hose will have been cut straight in the factory but we're still going to give it a trim. Get your hose cutter and make a straight, clean cut at the top of the hose, just taking enough off to level it out. Now, thread your outside collar into the hose, using your wrench to turn it counter-clockwise as you go. Make sure not to over-tighten the outside collar by looking into the fitting, the hose should just touch the base, and not overlap any threading inside the chamber.
