Description
When your hydraulic remote system starts getting sluggish or you notice oil weeping around the spool valve connections, those little O-rings inside are usually the culprit. These seals take a beating from constant pressure cycling and temperature changes, and when they start to fail, your hydraulics lose power and efficiency. This 50B spool valve O-ring gets you back to smooth, reliable operation.
What You’re Getting
- Pack of 10 precision-sized O-rings—replace them all while you’re in there
- Designed specifically for 50B spool valve applications in hydraulic systems
- High-pressure rated seals that won’t blow out under normal operating pressures
- Oil-resistant construction that holds up to hydraulic fluid and temperature swings
- Direct replacement for worn seals—no modifications needed
Built for Real Farm Work
These O-rings work in general purpose hydraulic applications where 50B spool valves control remote functions. Whether you’re operating a loader, running hydraulic motors on implements, or controlling cylinders on attachments, reliable sealing keeps your system running at full capacity. When the seals are fresh, your hydraulics respond quickly and smoothly to control inputs.
Made to Last
Hydraulic O-rings might look simple, but they do a tough job. These are made from hydraulic-fluid compatible materials that resist swelling, cracking, and hardening over time. The precise sizing ensures proper compression in the valve bore, creating a leak-tight seal without binding the spool.
Good to Know
Always replace all the O-rings in a spool valve at once—if one’s failed, the others aren’t far behind. Clean the valve bore thoroughly before installing new rings, and use a light coating of clean hydraulic fluid for easier assembly. The pack of 10 gives you enough for a complete valve rebuild plus spares for the next time.
