ZF 634801215 – Sealing Ring Ø42x49 mm for Marine Transmissions and Hydraulic Systems
The ZF 634801215 Sealing Ring is a durable and precisely engineered sealing component designed for marine transmissions and hydraulic systems. With an outer diameter of 42 mm and an inner diameter of 49 mm, it ensures a tight, leak-free seal in high-pressure environments. Manufactured from high-grade elastomer (NBR), it offers excellent resistance to oils, hydraulic fluids, saltwater, and abrasion. This sealing ring is ideal for submerged and rotating applications in marine conditions, withstanding temperatures from -30°C to +120°C and pressures up to 20 bar. It helps preserve hydraulic integrity, reduce wear, and extend component life.
Key Features:
- Outer diameter: 42 mm; Inner diameter: 49 mm – for precise, secure sealing fit
- Material: High-quality nitrile rubber (NBR) with saltwater and oil resistance
- Designed for use in ZF marine transmissions, pumps, and hydraulic shafts
- Effective sealing under submerged and high-pressure conditions (up to 20 bar)
- Operating temperature range: -30°C to +120°C
- High wear and abrasion resistance for long service life
- Easy installation and elastic recovery >90%
