Stainless Steel Male Connector – 3/8 in. Tube OD x 1/8 in. MNPT (SMC 6-2N)

The SMC 6-2N is a compact, high-performance male connector designed to join 3/8" tubing to a 1/8" Male NPT port with a leak-tight, corrosion-resistant seal. Constructed from 316 stainless steel, this straight fitting offers excellent strength and durability in pressure systems requiring clean routing, chemical compatibility, and fluid control precision.

Its dual-ferrule compression end ensures a secure grip and vibration-resistant seal, while the precision-cut NPT threads provide consistent performance in clean-in-place (CIP) loops, instrumentation lines, and OEM system builds. Ideal for sanitary environments, the SMC 6-2N is fully compatible with Swagelok® style tube fittings and process assemblies.

Whether you’re connecting sampling lines, controlling pressure in tight layouts, or building hygienic fluid processors, this fitting provides the compact solution you need for reliable long-term service.
