Leaking Lines

[Mark_G]

I acquired a logsplitter that mounts on my tractor from Tractor Supply. I keep having leaks where the hoses connect to the valve. I use thread paste with Teflon as advised and tighten well. The last time I let it dry for days before I used it and it still leaks. I cleaned the threads last time with an alcohol wipe to make sure it would seal well before I applied it. Any advice when I unscrew them yet again, clean them and re-attach?

Thank you,

I had the same issue with mine. I had to tighten them very very tight. I thought I was going to break the fitting but it finally stopped leaking.

If the threads are NPT, they deform to help make a seal. New hoses may be the answer if they have been taken apart a lot of times.

You might try Loctite 5452 on the threads.

It will work with the following, NPT, O-ring boss (ORB) or JIC fittings

NPT threads were never designed to be used over and over, about three to five times.

Install an adapter and go to JIC fittings.

Thanks all. They were/are new hoses for the splitter. I was afraid to tighten any further. I will see if I can find the locktite.

Is one end of the hose fittings a swivel?

If not, the pulsing and expansion of the hose can loosen the hose connection.

Are they indeed NPT threads?? or are they o-ring boss fittings that need the o-ring replaced???
