DK-LOK DUB Bulkhead Union
The DK-LOK DUB is a bulkhead union that carries a tube line through a panel or enclosure wall and joins two tube lines of the same outside diameter. The body passes through the panel and is secured with a bulkhead locknut. Both tube ends use DK-LOK’s twin (double) ferrule gaugeable design for a leak-free seal under vibration, vacuum, and impulse service. The base ‘DUB’ code carries no material suffix (-S/-B), so the alloy must be verified by the full part number.
