Stainless Steel SUC-6 | 3/8 in. Union Cross – High-Integrity 4-Way Tube Fitting

The SUC-6 is a precision-machined 3/8" union cross designed for four-way tube connections in instrumentation, high-purity, and sanitary fluid systems. Built from 316 stainless steel, it delivers corrosion resistance, pressure durability, and leak-tight performance for critical fluid and gas routing applications.

This compact cross fitting uses a dual-ferrule compression design on each port, ensuring secure tube grip and consistent sealing—even in high-vibration or thermally active environments. It’s ideal for clean-in-place (CIP) systems, gas distribution networks, and any process loop requiring rugged, multi-directional connectivity in a tight layout.

Compatible with Swagelok® style fittings, the SUC-6 is trusted by engineers working in biotech, chemical processing, and OEM equipment builds that demand high-integrity connections and long-term performance.
