Swagelok SS-400-3TFT Stainless Steel Female Run Tee, 1/4 in. Tube OD x 1/8 in. Female NPT x 1/4 in. Tube OD

The Swagelok SS-400-3TFT female run tee threads a 1/8 in. female NPT branch right into your 1/4 in. tube run. You seat your tube on both straight ports and screw a male pipe nipple, gauge stem, or bleed valve into the tapped center. That gives you a clean instrument takeoff without stacking adapters or adding joints. The 316 stainless body holds up to corrosive service and stays tight through pressure cycling and temperature swings. Both tube ends grip with the Swagelok two-ferrule mechanism you already count on, and the female NPT branch accepts standard tapered pipe threads. Instrumentation engineers reach for this tee to add a small gauge port or drain leg off a running 1/4 in. line. You order one part number and know exactly what lands on your bench. Pair it with Swagelok tubing and ferrules from Collins-Oliver so your whole assembly stays matched from stock. Call Collins-Oliver for a quote and pull it from Gulf Coast inventory.
