Stainless Steel SBHU-4 | 1/4 in. Tube OD Bulkhead Union

This 1/4″ straight fitting is engineered for dependable tube-to-tube connections through fixed walls, panels, or enclosures in high-pressure fluid systems. Made from 316 stainless steel, it combines corrosion resistance, mechanical strength, and long-term reliability, even in harsh service conditions. Its dual-ferrule compression seal provides a clean, metal-to-metal grip that prevents leaks under vibration, thermal cycling, or chemical exposure.

The compact, panel-mountable design allows tubing to pass securely through barriers while maintaining full flow and structural integrity on both sides of the wall. Precision machining ensures smooth tube engagement and consistent sealing performance without requiring adhesives or sealants, supporting repeatable installation and easy servicing. This efficiency makes it ideal for systems that demand uptime, cleanliness, and minimal maintenance.

Engineers frequently deploy this component in OEM skids, Clean-in-Place (CIP) infrastructure, chemical dosing systems, and sanitary-grade process loops. Its stable mounting point helps maintain organized layouts in crowded instrumentation panels or complex skid assemblies, reducing stress on tubing while allowing for cleaner routing. Because it withstands aggressive fluids, vibration, and pressure cycling, it has become a trusted solution for both industrial and high-purity applications.

In cleanroom environments, it supports precise fluid handling without introducing contaminants, while in industrial chemical networks it provides rugged durability for long service life. Whether used in new builds or retrofits, this fitting delivers consistent sealing performance and the flexibility needed to adapt to changing system requirements.
