AN Flare Bulkheads From:

Bulkhead fittings are versatile and handy fittings when you want to pass through a fire wall, tank, panel, fuel cell or a vehicle bulkhead.

Basically a bulkhead fitting seals off an area with the use of the jam nut. There is no need for grommets and passing long lengths of hose through

the vehicle. A real time saver!

*Bulkhead nuts sold separately (part number is 924)
