Swagelok SS-400-1-6 Stainless Steel Connector Fitting

Swagelok SS-400-1-6 is a stainless steel male connector tube fitting that attaches 1/4 in. outside-diameter tubing to a 3/8 in. male NPT threaded port. The part is machined from 316 stainless steel, delivering corrosion resistance and compatibility with a wide range of fluids and gases in laboratory and industrial systems. This straight, tapered-thread connector combines a tubing-end Swagelok fitting interface with a 3/8 in. MNPT thread on the port side, enabling a secure seal when paired with a matching 3/8 in. male NPT component and proper torque. Part of Swagelok’s tube fittings lineup, SS-400-1-6 is designed for reliable, leak-tight connections in instrumentation lines, manifolds, gas lines, and sampling systems where a robust metal-to-tubing interface is essential.
