ZF 634402538 – Sealing Ring Ø38 × Ø44 × 4 mm for ZF Marine Transmissions
The ZF 634402538 Sealing Ring is a precision interlocking piston seal specifically engineered for ZF marine and industrial transmission systems. Constructed from durable NBR (Nitrile Butadiene Rubber), this component ensures excellent hydraulic pressure retention, oil resistance, and long-lasting performance in high-load, high-speed environments. Its low-friction, wear-resistant design reduces component wear and promotes smoother piston movement. With a press-fit installation and interlocking geometry, the seal ensures a secure fit, minimizes leakage, and enhances the overall reliability of the transmission system.
Key Features:
- Engineered for ZF marine and industrial transmissions
- Made from wear-resistant NBR elastomer for long durability
- Low-friction surface for smooth piston operation
- Interlocking seal design ensures precise fit and secure sealing
- Excellent resistance to oils, fuels, and hydraulic fluids
- Rated for high-pressure environments up to 150 bar (2175 psi)
- Temperature resistant from –40°C to +150°C (–40°F to +302°F)
- Reduces leakage and improves hydraulic system efficiency
- Easy press-fit installation simplifies assembly and maintenance
- Ideal for high-speed, high-load piston applications
