One of the two 1/4 inch ID hoses from the skid steer to the quick attach grapple developed a leak. I went to the supplier today for a new hose. They were out of 1/4" fittings, so they sold me a 3/8" hose, with the correct ends. The rest of the hoses on the grapple are all 1/4" hoses. Can it do any harm to use the larger hose for the one hose connecting to the skid steer? It seems like it would be OK to me, but I don't want to do any damage to anything. Thanks.
For that, it'll be fine. As long as you can properly secure it, no problem .
You never have problems going bigger.
Seems I heard the wife say something similar once
Well as long as it wasn't your ex-wife telling you that!
As long as the pressure rating is the same as the replaced one... AND
