Built for Real Farm Work
This seal size shows up in transmissions, hydraulic systems, PTO assemblies, and axle housings across many tractor brands. Whether you’re dealing with a leaky transmission seal on your utility tractor or replacing worn hydraulic seals on a larger machine, these dimensions are common enough that it’s worth keeping a couple on the shelf for when you need them.
Made to Last
Farm equipment puts seals through the wringer with constant vibration, temperature changes, and exposure to different fluids. This seal uses materials specifically chosen to resist hydraulic fluid breakdown and maintain flexibility through hot summers and cold winters. The spring-loaded lips maintain proper sealing pressure even as components wear slightly over time.
Installation Notes
Before installing any seal, clean the housing bore thoroughly and check the shaft for scratches or wear that could cause leaks. Apply a thin coat of the appropriate fluid to the seal lip—never install it dry. Use a proper seal driver if you have one, or tap evenly around the outer edge with a block of wood. Installing crooked or with nicks in the lip guarantees a quick failure.
