Description
When your hydraulic system starts weeping fluid around a fitting connection, that little O-ring is usually what’s given up the ghost. This small but critical seal sits inside Weatherhead Z Series crimp fittings and keeps hydraulic fluid where it belongs – inside the system, not dripping on your shop floor or creating muddy spots in the field.
What You’re Getting
- Precision-sized 5/8 inch O-ring designed specifically for Weatherhead Z Series crimp fittings
- Oil-resistant rubber compound that handles hydraulic fluid, temperature swings, and pressure cycles
- Exact replacement that restores proper sealing without system modifications
- Quality construction that maintains flexibility under compression for reliable long-term sealing
Built for Real Farm Work
This O-ring is an essential component in Weatherhead’s Z Series crimp fitting system, which you’ll find throughout hydraulic systems on tractors, implements, and equipment. Whether you’re repairing loader hydraulics, fixing remote cylinder connections, or rebuilding hydraulic components, having the right O-ring ensures your fittings seal properly and your hydraulics operate at full pressure.
Made to Last
Despite their simplicity, O-rings face harsh conditions. Heat cycles cause them to harden and lose elasticity. Chemical exposure from fuels and fluids degrades rubber compounds. This replacement O-ring is engineered to handle those challenges with materials that resist hydraulic fluids and maintain their sealing properties through thousands of pressure cycles.
Installation Notes
Always clean the fitting thoroughly before installing a new O-ring, and check that the groove isn’t damaged or worn. A light coating of hydraulic fluid helps the O-ring slide into place without rolling or twisting. Don’t over-tighten the fitting – proper O-ring compression happens gradually as you snug the connection.
