Braided hoses offer great abrasion resistance but are harder to assemble than smoother coatings as they need a cover/socket to prevent unravelling of the braided strands. The stainless steel braid can rub against other components wearing through them like a file. Braided nylon hoses have an inner stainless steel braid covered by an outer nylon mesh to prevent this abrasion. The nylon mesh however can get dirty and gunked up with contaminates. These types of hoses are typically used with crimp or reusable type AN fittings.
Push lock fitting use hoses with smooth outer skins over braided mesh. The braided mesh strengthens and protects the inner liner that handles the fluid. Push locks are often used with fuel and oil and therefore must be compatible with the harsh fluids. Common types include silicon or PTFE. Alcohol or e85 fuels can degrade some types of inner liners and so must be used with compatible hose types. The smooth outer cover hoses can look like generic rubber hose but don't be fooled these hoses have multi-layer designs often with specific mesh weaves for the application. The multiple layer design allows the hose to be flexible but still maintain strength under high temperatures and pressures.

I want to completely re-hose one of our forklifts, and figure the cost of that might be enough to justify putting the money into a crimper and assortment of fittings/hose. I don't think it will be cost saving at the volumes I do over a year, but the added ability to make a hose at anytime seems well worth the trouble. Also being able to change a machine over 1 hose at a time rather than pulling/capping/marking a dozen hoses to drive over to the hose store. etc.
It would be great to hear from anyone who makes hoses. Other than hose, end fittings, and a machine..am I not thinking about any major space or cost factors involved? I feel like 3 hose sizes and 4-5 different style fittings for each would have made 90% of the hoses I have ever needed. Here is a picture showing a similar sized setup I think to the amount of stuff I am looking at adding, though I would keep mine more compact and stored away. Thoughts? thanks
