Engine Crankcase Breather Hose for Mercedes-Benz 300SEL

This URO engine crankcase breather hose is a direct replacement for the factory hose used on 1970-1973 Mercedes-Benz 300SEL models. It restores crankcase ventilation flow after the original hose hardens, cracks, or splits from heat and oil vapor exposure.

  • Material: AEM for resistance to engine heat and oil vapor
  • Molded hose design for OE-style routing and fit
  • Two hose connectors with one branch
  • End 1 inside diameter: 0.713 in.
  • End 2 inside diameter: 0.742 in.
  • Guaranteed fitment for the listed application
  • 24-month unlimited mileage warranty

Detailed Product Overview

Built for the crankcase ventilation system, this URO breather hose helps maintain proper airflow between engine components and the ventilation circuit. On Mercedes-Benz 300SEL applications, a worn hose can allow leaks that disrupt hydrocarbon control and reduce the effectiveness of the crankcase breather system. This replacement hose is shaped to match the original routing and uses AEM material to better withstand the operating environment around the engine.

This part number 1160940191 is a direct OE-style replacement for Mercedes-Benz 300SEL models from 1970 through 1973. It also cross-references URO-011605 for the same application.

What It Helps Fix

  • Cracked or split crankcase breather hose
  • Oil vapor leaks around the ventilation hose
  • Restricted crankcase ventilation flow
  • Improper hydrocarbon emission control from a failed OE hose
  • Fitment issues caused by a deteriorated molded hose

Installation Notes and Tips

Verify the hose routing and connector diameters against the original part before installation. Because this is a molded hose, correct orientation matters for proper fit on the Mercedes-Benz 300SEL crankcase ventilation system. Inspect nearby breather and vacuum components for age-related wear while the hose is removed.

Quality Assurance

URO backs this replacement hose with a 24-month unlimited mileage warranty. The part is built from heat- and oil-vapor-resistant material and is intended to restore crankcase breather function on the listed Mercedes-Benz 300SEL applications.
