When your hydraulic lines start weeping or you notice that telltale puddle forming under your tractor, it’s usually one of these small but critical seals that’s giving up the ghost. This HM18 metric seal with its precise 0.438-inch width is designed to keep hydraulic fluid where it belongs—inside your system, building pressure and moving implements instead of staining the ground.
What You’re Getting
- Metric HM18 designation ensuring exact fit for European and modern tractor hydraulic fittings
- 0.438-inch (11.13mm) width specification for precise sealing in hydraulic connections
- High-pressure resistant construction that handles the demanding loads of agricultural hydraulics
- Quality rubber compound designed to resist hydraulic fluid breakdown and maintain flexibility
Built for Real Farm Work
This seal fits hydraulic systems found on tractors with metric hydraulic fittings—common on newer equipment and many European brands. Whether you’re dealing with loader circuits, three-point hydraulics, or remote valve connections, this seal maintains the tight tolerances needed for efficient hydraulic operation.
Made to Last
Hydraulic seals take a beating from constant pressure cycles, temperature changes, and exposure to hydraulic fluids. This HM18 seal uses materials specifically chosen to resist swelling, cracking, and hardening that kills cheaper seals. It’s built to maintain its sealing properties through thousands of pressure cycles.
Installation Notes
Always clean the sealing surfaces thoroughly before installation—any contamination causes immediate failure. Use proper installation tools to avoid nicking the seal during installation. A light coating of clean hydraulic fluid on the seal helps it seat properly without damage.
