Stainless Steel Bulkhead Female Connector – 1/4" Tube x 1/4" FNPT (SBFC 4-4N)
The SBFC 4-4N is a stainless steel bulkhead female connector designed to securely transition from 1/4" tubing to 1/4" Female National Pipe Taper (FNPT) threading through a panel, enclosure, or equipment wall. It offers a leak-tight, vibration-resistant seal in both industrial and sanitary systems.
Built from 316 stainless steel, the SBFC 4-4N provides superior resistance to corrosion, chemical exposure, and pressure-related fatigue. This fitting installs cleanly into skids, control boxes, and system frames using its integral locknut and body threads—offering a firm anchor point for fluid system routing.
Ideal for fluid or gas transfer across panels, this connector is frequently used in instrumentation builds, test stands, and Original Equipment Manufacturer (OEM) fluid assemblies. It supports Clean-in-Place (CIP) use and requires no sealants on the compression end.
Key Benefits
- Provides a secure tube-to-female-thread connection through panels
- Compression side delivers leak-tight performance without sealants
- 316 stainless steel body resists corrosion, vibration, and media contamination
- Locknut and body threads allow rigid mounting on panels or skid walls
- Fully reusable and easy to reinstall in OEM service builds
- FNPT side fits standard 1/4" NPT-threaded valves, regulators, or sensors
Typical Applications
- Original Equipment Manufacturer (OEM) process skids and test panels
- Clean-in-Place (CIP) instrumentation lines
- Skid-mounted or cabinet-mounted gas or liquid systems
- Sensor port extensions and panel-mounted valve interfaces
- Control panel penetrations and high-purity transfer systems
