When your hydraulic pump starts leaking from the main shaft, that’s usually the silicon carbide seal calling it quits. This precision seal might look like a small part, but it’s the only thing standing between your expensive hydraulic fluid and the ground underneath your tractor. A worn seal doesn’t just make puddles—it kills pump pressure, makes your three-point sluggish, and can damage other pump components if you keep running it.
What You’re Getting
- Precision-ground silicon carbide faces that create a leak-proof seal under high pressure
- Complete with the matching O-ring so you’re not hunting for parts
- Heat and abrasion resistant materials that handle dirty farm conditions
- Direct replacement seal that fits properly without modifications
- Professional-grade construction that maintains sealing under variable pressures
Built for Real Farm Work
This mechanical seal is designed for hydraulic pumps in tractors and agricultural equipment where shaft sealing is critical. Whether it’s your main hydraulic pump, power steering pump, or auxiliary hydraulic systems, this seal handles the pressure and contamination that come with farm work. It’s built to seal rotating shafts where standard O-rings just won’t cut it.
Made to Last
Silicon carbide isn’t just fancy—it’s one of the hardest materials you can use for a seal face. It resists scoring from dirt and debris while maintaining a smooth sealing surface that doesn’t wear out your pump shaft. The included O-ring uses quality rubber compounds that stay flexible through temperature swings and resist breakdown from hydraulic fluids.
Installation Notes
This is definitely a clean-hands job—any dirt or scratches on the seal faces will cause immediate failure. Take your time during installation and keep everything spotless. The seal orientation matters, so pay attention to how the old one comes out. A thin coat of hydraulic fluid on the O-ring helps it slide into place without damage.
