Swagelok SS-T4-S-035-20 316/316L Stainless Steel Seamless Instrumentation Tubing, 1/4 in. OD x 0.035 in. Wall, 20 ft.

Run your instrument lines on tubing that holds its shape and grips your fittings the first time. The Swagelok SS-T4-S-035-20 gives you 1/4 in. outer diameter, 0.035 in. nominal wall, dual-certified 316/316L stainless steel in a clean 20-foot length. You get a fully annealed, seamless wall that bends without kinking and takes a leak-tight ferrule bite in analytical, sampling, and pressure-sensing runs. Refineries, chemical plants, and power stations reach for this size because it fits gauge lines, transmitter tubing, and compact panel work where 1/2 in. is simply too big. The 316/316L chemistry fights chloride pitting and stands up to the corrosive service your plant throws at it. Every stick ships hardness-controlled so your Swagelok, DK-LOK, or Parker fittings seat cleanly. Need a different wall, length, or alloy for your application? Call Collins-Oliver and we will match it. Order the exact size you need and keep your instrumentation loops tight, accurate, and ready for inspection.
