DK-LOK DUBA-S AN Bulkhead Union

The DK-LOK DUBA-S is an AN bulkhead union that joins a DK-LOK twin-ferrule tube end to a 37-degree AN flare (SAE J514) through a panel wall, secured with a bulkhead locknut. The ‘-S’ designation indicates a 316 stainless steel body. It combines AN flare interfacing with panel-mount bulkhead capability for high-vibration, high-pressure AN systems.
