Protect your transmission from contamination with this Genuine Nissan Transfer Case Breather Hose, designed to suit all Nissan Patrol GU Y61 models. This OEM rubber hose connects the gearbox breather pipe to the chassis-mounted breather pipe, allowing the transmission to vent internal pressure while helping prevent water, dust, and debris from entering the gearbox.

Located close to the exhaust system, the original breather hose is exposed to constant heat, causing the rubber to harden, become brittle, and eventually crack. A damaged breather hose can allow water and mud to enter the gearbox during off-road driving or water crossings, potentially leading to contaminated transmission oil and costly internal damage. Replacing it with a Genuine Nissan component restores the factory breather system and helps protect your transmission in all driving conditions.
