Hydraulic Hose Size

[jgbanshee]

I plan on routing two hydraulic hoses from my rear remotes up to the cross-member between the FEL arms for a grapple and power angle snow plow. My tractor specs the max flow for the rear remotes is 8 GPM. Should I use 3/8" hose with 1/2" QC's or 1/2" hose with 1/2" QC's. Either way the hose length will be 16' long. I dont think that heat is a problem because they are only used for a grapple and snow plow.

I used 3/8 for both uses with no problem. Some guys suggest 1/4 for grapple to slow them down.

That's what I'd do.. 1/4 hoses.. cheaper too.

I agree, 1/4" hoses. The 8 GPM figure is irrelevant because its not the cylinders for the plow or grapple do not require constant flow.

 

[jgbanshee]

So, the majority agrees that I should use 1/4" hose. Does the 8 GPM rating matter for any implement? What size QC's should I use?

What size QC's should I use?

Use 1/4" or 3/8" QD's, whatever is easier to get...does not really matter.

Does the 8 GPM rating matter for any implement?

Only if it requires constant flow-like a hydraulic PHD.

yeah.. hyd motors.. that's where high sustained flow is needed.

It is recommended to use one size larger QC for full flow.

 

[Soundguy]

I think he's actually looking 'for' restriction.. if he wanted full flow.. we'd be telling him 3/8 hose at least.

If you think you might ever use a hyd motorized attachment on the front, I would go with 3/8 in hose, and 1/2 QC's. You could still add a restrictor in the line, or a needle valve.
