Log spliter qustion

[WranglerX]

Get quality hydraulic return line and with proper barbed connector worm type hose clamps should be good.... THe hoses on my splitter wer 25 years old ans still good (I think) but in adding new engine and I decided to replace hoses and filter. Tha ias about 5 years ago, all is still good........

I bought a 3/4" hyd. Hose all good now except oil filter I might have to change that because the gasket around it did not stop the fluid and it went on the floor.

Well I changed the line from 1/2" to 3/4" I bought a clear line and put it on and started the spliter and it spit fluid all over! .
I use hose clamps on each end I checked before starting the spliter I think I have to buy pex crimp rings and a better line.

Now you know why it's just worth buying a hydraulic hose for a return line. 2gal of fluid prob cost the difference between low pressure hose and a hydraulic hose.

Surplus center is where I got all my 3/4 log splitter lines.

Might look here... But my 22 ton splitter uses 1/2 inch hoses on pressure and 3/4 bulk onreturn sides....

Many of the 22 ton splitters only have 11 gpm pumps, and so it's normal to use 1/2" on high pressure side, 3/4" on low pressure side.

Heck, i think most hydraulic lines on my tractor are only 1/2”.

Most tractors flow a heck of a lot less fluid through their SCV and auxiliary lines, than a log splitter.

You want proper hydraulic lines for everything except the suction line between the tank and pump inlet. Assuming your filter is on inlet to tank, any line between the pump and filter can see some pressure, even if it's only super high between pump and cylinder. The suction line should be proper suction line, as regular unreinforced hose can collapse.

Mine came with clear hose.
Use collar type clamps.

Is it at least re-inforced?!?

The most popular clear tubing that is resistant to hydraulic oil would be clear versilon PVC plastic, which has a max pressure rating of only 30 psi at 72F in 3/4" ID... and burst pressure goes down with temperature.

There are hard (semi-flexible) clear plastic tubings, such as polyethelene tubing that has a pressure rating of 190 psi at 72F and a max working temperature of 180F, but this is still incredibly low for a hydraulic system. This essentially translates to a blown line anytime someone is a little lax on their filter change routine.

No
There are no threads running through the tube.
It has stayed put for 10 yrs.
This is on a 16 tonner.
It is sufficient for the suction side of that splitter.

I had thought you said low pressure side, which still sees positive pressure, depending on flow rate, viscosity, and filter condition. The pressure there should be relatively low, but it's still positive pressure.

But suction tube is another matter, that's actually at negative pressure relative to atmosphere. A suction tube may collapse inward, but will never blow out.

Yes you are correct.
Low pressure return needs to be fitted hydraulic hose.
Had to read the op again.

There is pressure on the return line! It blew a hole in the clear line I had that why I bought a hdy. line it has 31 or 3200psi.
