Swagelok SS-400-9 Stainless Steel Union Elbow, 1/4 in. Tube OD

Turn your tube run a hard 90 degrees without adding bulk. The Swagelok SS-400-9 union elbow joins two 1/4 in. tube ends and locks each one down with the proven Swagelok two-ferrule design. You get a leak-tight seal you can gauge on the first pull-up, so your instrumentation lines stay tight under vibration, pressure cycling, and thermal swing. The 316 stainless steel body shrugs off corrosion in refinery, petrochemical, and analytical service, and the compact footprint fits the tight panels your engineers actually build. No welding. No torch permits. Just cut the tube, insert, and tighten. Reassemble it again and again and it seals every time. Collins-Oliver stocks this fitting for Baton Rouge plants that cannot afford a dripping connection. Working pressure depends on your tube wall, so call for your application and we will match the part to your line. Request a quote and keep your project moving.
