Swagelok SS-600-4 Stainless Steel Tube Fitting Union Cross

SS-600-4 is a four-port union-cross stainless steel tube fitting from Swagelok, designed for four 3/8 in. outer-diameter tubes. The “SS” prefix denotes 316 stainless steel construction, providing corrosion resistance in demanding environments. This union cross features four equal ports arranged in a cross geometry and is intended for use with standard Swagelok 3/8 in. tube fittings to create a single, compact cross junction that can branch fluid paths in instrumentation, analytical setups, or process piping. By maintaining a consistent 3/8 in. tube OD across all ports, SS-600-4 enables modular manifolds and scalable pipe networks while ensuring compatibility with other Swagelok components. This part supports reliable, leak-tight connections in systems where stainless steel and compact cross-branching are essential, making it suitable for laboratory benches, chemical processing lines, and instrumentation racks that require a robust four-way junction in stainless steel.
