Stainless Steel Male Adapter – 3/8" Tube Stub x 1/4" Male NPT

The SMA 6-4N is a 3/8" tube stub to 1/4" NPT male adapter designed for hygienic fluid processors, pressure systems, and clean gas or liquid transfer applications. Precision-machined from corrosion-resistant 316 stainless steel, this sanitary stainless steel fitting ensures leak-tight connections and long-term durability, even in aggressive or high-purity environments.

● Material: 316 Stainless Steel (Corrosion-Resistant Alloy)
● Connection Type: 3/8" Tube Stub x 1/4" Male NPT
● Applications: Clean in place instrumentation, hygienic valves, sanitary process systems, OEM skids, gas sampling panels

Often used alongside compression fittings and instrumentation assemblies, this adapter integrates easily into systems demanding precise fluid control. It’s also a direct Swagelok SS-600-TA-4-2 equivalent, offering engineers a high-performance alternative that meets the same rigorous standards.

The SMA 6-4N is ideal for sanitary and industrial piping layouts that require space efficiency, corrosion resistance, and uncompromised cleanliness. Whether you’re outfitting a lab, a CIP loop, or a high-pressure gas line, this adapter delivers consistent performance and full compatibility with hygienic process setups.
