DK-LOK DUB-B Bulkhead Union (Brass)
The DK-LOK DUB-B is a brass bulkhead union that carries a tube line through a panel or enclosure wall and joins two tube lines of equal outside diameter. The body mounts through the panel and is secured with a bulkhead locknut. Each tube end delivers a reusable twin (double) ferrule seal. The ‘-B’ designation indicates brass construction, suited to general-purpose and lower-corrosion service.
