ZF 634306204 – O-Ring 22x32x3.5 mm NBR/FKM 70 Shore A for Marine Engines and Gearboxes
The ZF 634306204 O-Ring is a robust sealing element designed to deliver leak-free performance in high-pressure and high-temperature systems. Constructed from high-quality nitrile rubber (NBR) or fluoroelastomer (FKM), it provides excellent resistance to oils, fuels, water, and a wide range of chemicals. This O-ring is ideal for static applications such as dipstick systems, gearboxes, and marine engines, helping to protect internal components from contamination and fluid loss.
Key Features:
- Material: NBR or FKM for chemical and thermal resistance
- Rated for temperatures from -40°C to +150°C
- Pressure resistance up to 60 bar (870 psi)
- Provides a secure seal to prevent fluid leakage and contamination
- High elasticity for a tight, durable fit
- Suitable for marine, automotive, and industrial use
- Precision dimensions ensure easy installation and reliable operation
