Swagelok 316 RS ISO228 S12 Tube Fitting

Swagelok SS-12M0-1-2RS is a 316 stainless steel tube fitting designed for 12 mm OD tubing with a male ISO 228 parallel-thread connection (RS). It belongs to Swagelok’s gaugeable tube fittings family and uses a two-ferrule, compression-grip design to form a reliable seal when mated with compatible female components. The 316 stainless steel body provides corrosion resistance suited for demanding fluid systems, while the RS (ISO 228) end connection ensures standard parallel-thread compatibility with ISO 228 fittings. This part is cataloged as a 12 mm tube fitting with RS (ISO parallel) threading, aligning with Swagelok’s RS-series fittings documented in their product literature.
