Swagelok B-12-RA-8 Brass Compression Tube Fitting

Swagelok B-12-RA-8 Brass Compression Tube Fitting is a brass-bodied compression fitting designed to connect 12 mm outside-diameter tubing in instrumentation and process piping. Listed in Swagelok's catalog with Basic Ordering Number -12-RA-8, this part uses a standard Swagelok compression nut and ferrule to seal a 12 mm tube. The item’s dimensions include approximately A = 2.02 in (51.3 mm) overall length and E = 0.47 in (11.9 mm) for the interface, with brass construction providing corrosion resistance in typical laboratory and chemical-processing environments. The -12-RA-8 family carries material- and configuration-dependent pressure ratings, so the exact maximum pressure varies by setup, but it is intended for reliable, repeatable connections in systems that use 12 mm Swagelok-compatible tubing.
