Swagelok SS-T8-S-035-20 Seamless 316/316L Stainless Instrumentation Tubing, 1/2 in. x 0.035 in. Wall

Your fittings are only as good as the tube they grip. The Swagelok SS-T8-S-035-20 gives you seamless, fully annealed 316/316L stainless steel instrumentation tubing built to gauge tight and seal clean. Each length measures 1/2 in. OD with a 0.035 in. wall and ships in a 20 ft run. Swagelok holds this tubing to hardness and finish standards that let your tube fittings bite and hold the first time, so you avoid the leaks that come from hard, out-of-round, or scratched tube. It arrives chemically cleaned and passivated to ASTM G93 Level A and CGA 4.1, which keeps your analytical and high-purity lines free of contamination. The tubing carries an allowable working pressure of 2600 psig at ambient temperature and meets ASME B31.1 and B31.3 listings for power and process piping. Refineries, petrochemical plants, and instrumentation engineers across Baton Rouge run this exact size on gauge lines, sample loops, and impulse lines. Collins-Oliver stocks 316/316L instrumentation tubing by the length and the box. Call for a quote.
