I posted the need for some parts for the rebuild of my Hydraulic system, piston, Cylinder and "O" Rings Kubota L275. NO one, No one had the "O" Rings either single or in a kit. The big was the Back Up Ring on the piston $68.00 for one from Kubota and other sources. I dismantled the assembly and took it to my local Gasket and "O Ring company, they fixed me up with metric "O" rings and a back up ring (not exact) but will work, same material Complete set $20.
