AN fittings and hoses are often found installed on high performance and race cars. AN hoses are used for fuel, oil, coolant and hydraulic fluids. AN stands for Army-Navy as the specification was developed based on a standard for flexible fluid connections used during World War II. They are often used in aviation but like most high performance aviation equipment they eventually ended up on race cars and then street cars.
People use AN fittings because they look cool and provide a secure fitting that seals hoses better than traditional push on nipples and hose clamps. They form a serviceable connection that provides a reliable seal. AN fittings can also be used for leak free bulkhead pass throughs like those found on the outside of fuel cells.
Nice kit, with out the premium price. A must for power strokes. Comes from over seas. Took about 10 days to receive, with good Communication along the way. Going to consider other offerings from SPELAB.
Good material, good prices,
Only the flanges need to adapt, perfect fit just need modifications in the connection to the pipes, different angle 📐 flange need more than 90 degrees to fit the pipes , other than that is perfect fit in the engine M54, my chassis is E46 thanks for the product
