Durable EPDM Material and Molded Construction

The URO ERR4763 breather hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. This material choice helps maintain hose integrity under engine bay conditions. The molded design ensures the hose matches the exact contours required for proper fitment on Land Rover Defender 90, Defender 110, Discovery, and Range Rover vehicles. With two hose connectors and no branches, the hose provides a direct and secure path for crankcase ventilation.

  • Reduces oil vapor and emissions entering the intake system
  • Helps avoid engine performance issues related to crankcase ventilation failure
  • Minimizes risk of oil leaks and contamination in the engine bay
  • Supports compliance with emission control standards

Installation Notes and Tips

The molded shape facilitates alignment, but care should be taken to avoid twisting or stretching the hose during installation. Inspect surrounding components for wear or damage to maintain overall system integrity.
