Rein Crankcase Breather Hose

The Rein Crankcase Breather Hose line offers replacement crankcase ventilation hoses, also called PCV hoses or engine breather hoses. They are engineered for European vehicle applications. The crankcase ventilation system routes blow-by gases from the engine crankcase back to the intake so they can be burned. This helps control internal engine pressure and keeps emissions down.

Key Features:

• Direct-fit replacement design that follows the original equipment hose routing and connection style
• Made from oil- and heat-resistant materials suited to the under-hood environment
• Helps restore proper crankcase ventilation when original hoses have become brittle, cracked, collapsed or leaky
• Helps prevent oil leaks, vacuum leaks, rough idle and excess crankcase pressure caused by worn hoses
• Available in multiple part numbers, each matched to a specific engine ventilation application

Rein is an aftermarket supplier of replacement parts for European vehicles. Replacing an aged breather hose is a practical maintenance step that supports reliable engine operation and long-term durability.
