Swagelok SS-400-3 Stainless Steel Union Tee, 1/4 in. Tube OD

Need to branch your 1/4 in. tube line three ways without a single leak path? The Swagelok SS-400-3 union tee gives you three gaugeable tube-fitting ports on one 316 stainless body. Every end grips your tube with the proven Swagelok two-ferrule mechanism, so you get a leak-tight seal you can pull up by the numbers and walk away from. You install it fast, you inspect it fast, and you trust it under vibration and pressure cycling. Refineries, chemical plants, and analytical system engineers across Baton Rouge reach for this exact part when they split instrument lines, add a gauge tap, or tie in a bleed leg. The 316 stainless body shrugs off corrosive service and holds its integrity through temperature swings. You order one part number and you know precisely what shows up. Match it with Swagelok tubing and ferrules from Collins-Oliver and your whole connection stays consistent from stock. Call Collins-Oliver for a quote and pull it from local inventory.
