730 loader hose leaks at swivel fitting

Hey folks, my bucket tilt hoses are leaking at the fittings. Any repair tips appreciated. Can they be repaired or do I need new hoses? Any advice on undoing the pipe fitting end of hose and ensuring a leak free connection when done?

Since the cover is falling off needs new hoses. Hose shop can make exactly like old ones.

Unless absolutely needed I do away with those hose fitting with the swivel made in them. I would look at changing the one in your cylinder picture to a 90 degree JIC adapter that threads into the cylinder (I'm guessing that is male NPT) and have the hose end be a JIC swivel of the matching size. 99 percent of the time those built in swivels are just another place to leak in my opinion and experience.

Yes, I want this to be done first time without leaks and to be safe but not overly expensive. The local hose shop charges around $80 per hose. Some hose pros on youtube said don't buy hoses at Tractor Supply, because they are prone to blow outs. I don't know what pressure rating I need for this loader, the hose pressure info is not visible. Looks like most hoses at TSC are rated 3000 to 4000 psi. Just looking for member experiences here with the same loader.

Your loader pressure should be in the range of 1900 to 2200 PSI, it depends on the pump and relief valve setting for your specific unit. I have used pre-made hoses from TSC, Surplus Center, and others as well as having hoses made at hydraulic shops and parts stores. Some reasons the premade ones are less expensive are: they aren't a brand name, they are made in fixed lengths, size diameters are limited, and end fitting styles are limited. The only drawbacks I see for the most part with the pre-made hoses, if available in diameter and pressure rating needed, are the end fitting selection is limited where fit maybe affected by having to add an adapter and the lengths may not be just what you want. I haven't experienced a problem with blowouts as long as the hose pressure rating is above the main relief pressure, plus some for a shock loading margin. I would use a premade TSC NPT hose on a loader like yours (got some on my JD). You can get a female NPT x female NPT swivel NPT adapter for the tube end and a 90 degree male pipe x female NPT swivel adapter on the cylinder, so you have a swivel on both ends to ease installation. Always use real hydraulic adapters and fittings, not hardware store fittings. Run and tight the hose without twisting the hose itself, that can cause failures. Hoses also have minimum bend radii, bending too tightly can lead to failure. Use a paste thread sealant on the tubing threads and the fitting that threads into the cylinder. The swivel fittings should have seats in them to match the internal seat in the hose end so sealant is not required, they seal on the seats, not the threads.
