ZF 634304106 – O-Ring 34x42x4 mm (3425 NBR70) for Gearboxes, Pumps, Engines

ZF 634304106 – O-Ring 34x42x4 mm (3425 NBR70) for Gearboxes, Pumps, Engines

The ZF 634304106 O-Ring (3425 NBR70) is a high-performance sealing component engineered for marine, industrial, and automotive systems. Made from Nitrile Rubber (NBR) with a hardness of 70 Shore A, this O-ring delivers reliable resistance to oils, fuels, hydraulic fluids, and petroleum-based liquids. It ensures a secure and leak-free seal in components such as gearboxes, pumps, engines, and hydraulic systems, even in moderate to high-pressure environments. Easy to install and meeting ISO 3601-1 standards, it is ideal for applications requiring long-lasting, durable sealing under thermal and mechanical stress.

Key Features:

• Manufactured from NBR 70 Shore A for strong, resilient sealing
• Excellent compatibility with oils, fuels, and hydraulic fluids
• Suitable for pressure up to 1.5 MPa (217.5 psi)
• Temperature range: -40°C to +120°C
• Resistant to water, oil, and petroleum-based substances
• Standard circular O-ring shape for easy replacement and installation
• Minimizes leakage, contamination, and system wear
