Bulkhead fittings are versatile and handy for when you want to pass through a firewall, tank, panel, fuel cell, or a vehicle bulkhead. A bulkhead fitting seals off an area with the use of a jam nut. There’s no need for grommets and passing long lengths of hose through the vehicle. A big time saver!
Steel, nickel-plated bulkhead nuts also available in -3 size.
