ARB 4x4 Accessories 170112 Differential Axle Breather Kit for drivetrain differentials, transmissions and transfer cases

#ad
ARB #ad - The air filter is the arb compressor air filter, which is a splash resistant air filter with a washable high flow sintered bronze filter cartridge. The manifold has 4 axle breather ports allowing for between 1 and 4 breather lines to be connected.

The 8mm push-in fittings make the installation simple and fast. It is very compact allowing it to be installed in virtually any location. 8mm polyethylene tubing is flexible, oil resistant, water resistant and heat resistant. 8mm tubing has been selected over the standard 6mm tubing to improve the air flow and reduced the chance of oil blockages in long breather lines.

The kit comes with self tapping screws, but the manifold mounting holes are large enough to allow mounting using an M6 1/4 inch bolt or stud, which is the common size in most vehicle engine bays. The axle breather manifold is machined from billet aluminium and anodized, making it lightweight and resistant to the elements.
