Description
Compression bulkhead unions pass instrumentation tubing through a panel wall with double ferrules on both sides. FerruleX bulkheads in SS316/SS316L/SS304 cover OD 3–25 mm / 1/8"–1" and lock with a bulkhead nut for enclosure thickness. Control cabinets, analyzer shelters and skid walls stay sealed without welding a tube stub through the plate. Standard classes follow the tube OD and wall per the maker's table; several-thousand-psig ratings are typical in small OD. Confirm panel thickness and OD on the RFQ. Values are class-typical references for this configuration; tube OD, wall and pressure class are confirmed on the RFQ. FerruleX stocks frequent bulkhead sizes for fast factory shipping after quote. Drill the panel hole to the recommended diameter so the locknut seats flat without tilt.
Drill the panel hole to the bulkhead’s recommended diameter so the locknut seats flat without crushing the gasket face. If the wall is thicker than the nut stack allows, call it out — FerruleX can extend the shank on OEM lots. Label both sides of the panel during install so maintenance knows which nut is the process side.
- Mounting
- Bulkhead locknut for panel thickness ranges.
