When you’re fighting sluggish three-point hitch operation or spotting hydraulic fluid drips around your lift cylinders, worn piston sealing rings are often the culprit. You know the signs: hydraulic fluid on the garage floor, pump whining from low fluid, or that three-point hitch that won’t stay up anymore. This sealing ring keeps your hydraulic system sealed tight where the piston does its work, preventing those frustrating leaks that rob power and make a mess.
What You’re Getting
- Precision-molded sealing ring designed specifically for MF hydraulic cylinder pistons
- Quality rubber compound that resists hydraulic fluid breakdown and temperature swings
- Direct replacement that fits properly without modifications or adapters
- Durable construction that handles the constant pressure cycles of hydraulic operation
Built for Real Farm Work
This sealing ring fits an impressive range of Massey Ferguson tractors from the legendary 35 and 65 series through the popular 100, 200, 300, 500, and 600 series machines. Whether you’re running a compact MF 35 on hay equipment or operating a bigger 300 series tractor on row crops, these are the workhorses that power three-point implements, loaders, and remote hydraulics day in and day out.
Made to Last
Quality rubber compounds resist hydraulic fluid and temperature extremes while maintaining the flexibility needed for reliable sealing. This ring is engineered to handle the demanding conditions of agricultural hydraulic systems, from sub-zero morning starts to hot summer field work with heavy implements.
Good to Know
Resealing your hydraulic system is a perfect winter shop project. Start by thoroughly cleaning the outside of all components – you don’t want dirt falling into open hydraulic lines. Work systematically through each component: pump, control valve, lift cylinder, and all line connections. Clean each O-ring groove carefully with a pick or small screwdriver – old O-ring fragments left behind cause comeback leaks. Use a bit of hydraulic fluid on new O-rings during installation; never force them.
