Gates EMH105 Engine Crankcase Breather Hose

The Gates EMH105 is a direct-fit engine crankcase breather hose, also known as a PCV (Positive Crankcase Ventilation) hose, engineered to OE-exact specifications for a precise, reliable replacement. Designed as part of Gates' comprehensive emission control and ventilation hose line, this hose restores proper crankcase ventilation system function and performance.

Key Features:

• OE-Exact Fit: Engineered to match original equipment specifications for a direct, hassle-free installation with no modifications required
• High-Quality Materials: Constructed from durable rubber and/or plastic compounds built to withstand heat, oil vapors, and the demands of the crankcase ventilation environment
• Wide Temperature Range: Rated for temperatures from -40°F to +275°F (-40°C to +135°C) for reliable year-round performance
• Emission System Restore: Effectively returns the PCV and emission control system to proper operation, helping prevent pressure buildup, oil leaks, and excessive oil consumption
• No Remanufactured Components: Built entirely from new materials for maximum service life

The crankcase breather hose carries blow-by gases and oil vapors from the engine crankcase to the intake manifold, where they are re-burned rather than released into the atmosphere. A failed or degraded breather hose can result in increased crankcase pressure, oil leaks, rough idle, and reduced engine performance. The Gates EMH105 is a trusted OE-quality replacement that keeps the ventilation system operating as intended.
