Description

When you’re out in the field and notice fluid seeping around your tractor’s axle or hydraulic components, that little rubber ring might not look like much—but it’s what keeps everything sealed tight and working right. This square axle O-ring is designed to handle the unique sealing challenges around square axle shafts where standard round O-rings just won’t do the job.

What You’re Getting

Precise fit for square axle shafts—no more trying to make round seals work on square applications
High-quality rubber compound that stands up to hydraulic fluids, gear oils, and temperature swings
Flexible design that maintains a tight seal even as components move and vibrate during operation
Direct replacement that installs without modifications or special tools

Built for Real Farm Work

This O-ring fits a wide range of Massey Ferguson tractors from the compact 100 series utilities all the way up to the big 600 series row-crop machines, plus articulated tractors and industrial telehandlers. Whether you’re running a 240 on hay ground, pulling implements with a 399, or operating a telehandler around the farmyard, this seal keeps critical fluids where they belong.

Made to Last

Farm equipment operates in tough conditions with dust, moisture, temperature extremes, and constant vibration. This O-ring is manufactured from premium rubber compounds that resist swelling from fluid contact while staying flexible enough to maintain sealing pressure through years of use.

Installation Notes

Clean all sealing surfaces thoroughly before installation and check for any nicks or damage that could cause leaks. A light coating of clean hydraulic fluid helps the O-ring slide into position without damage. Replace any O-rings you disturb during repairs—if one has failed, others are likely getting marginal too.
