The ARB High Pressure Bulkhead Kit (6mm to 35mm O-Ring Type) is an essential replacement hardware component designed for high-performance ARB Air Locker installations and heavy-duty onboard air systems. Engineered to create a leak-free, high-pressure seal through axle housings or firewall barriers, this heavy-duty bulkhead fitting converts and secures 6mm air lines into 35mm O-ring style ports with precision and reliability.
Manufactured from corrosion-resistant nickel-plated brass and fitted with high-durability rubber O-rings, this fitting withstands extreme trail vibration, thermal expansion, and intense air pressures generated by heavy-duty onboard compressors. Designed to fit flush against axle housings or structural brackets, the bulkhead assembly ensures smooth air pressure delivery to actuate differential lockers without pressure drop or air loss. Ideal for overland vehicles, rock crawlers, and custom 4x4 builds, this genuine ARB component maintains peak locking differential performance in demanding off-road conditions.
