Stainless Steel SBHU-4 | 1/4 in. Tube OD Bulkhead Union (SBHU-4)
The SBHU-4 is a 1/4" tube OD bulkhead union designed for secure tube-to-tube connections through panels, walls, or enclosures. Built from corrosion-resistant 316 stainless steel, this fitting supports full-flow media transfer while maintaining leak-tight integrity in pressure-rated systems.
Its compact, panel-mountable body and dual-ferrule design offer long-term performance under vibration, thermal shifts, and corrosive exposure. Ideal for instrumentation panels, OEM skids, clean-in-place (CIP) systems, and sanitary stainless steel setups, the SBHU-4 provides consistent sealing without compromising layout flexibility.
Compatible with Swagelok® style compression systems, it’s a go-to component for cleanroom installations, chemical dosing stations, and any application where precise routing through a barrier is required.
Key Benefits
- Seal: Dual-ferrule compression grip for secure, leak-tight performance
- Mounting: Panel-ready bulkhead design for clean routing through enclosures
- Durability: Resists corrosion, vibration, and system cycling
- Compatibility: Works with 1/4" stainless tubing and Swagelok® alternative fittings
- Material: 316 stainless steel supports hygienic and high-purity applications
Typical Applications
- Sanitary stainless steel fluid systems
- Bulkhead isolation in cleanroom and lab builds
- Chemical injection and dosing skids
- OEM instrumentation panels and analyzer racks
- Clean-in-Place (CIP) and hygienic process lines
