Bulkhead union tube fitting / official catalogInstrumentation Fittings
Precision tube fittings for instrumentation, process impulse lines, hydraulic circuits, and assemblies that need a reliable connection under pressure.
Arcellor Controls' catalogue includes unions, elbows, tees, crosses, reducers, bulkhead fittings, adapters, caps and plugs for connecting instrument tubing and pipework. Compression tube fittings use a ferrule connection, while threaded or welded connections require a matching interface. The pictured bulkhead union is one example, not a specification for the whole range.
