Swagelok SS-1210-6 Stainless Steel Straight Union

SS-1210-6 is Swagelok’s stainless steel straight union that connects two 3/4 in. tube OD lines with a leak-tight seal in a straight run. The union uses a 316 stainless steel body with Swagelok tube fittings on both ends, each sized for 3/4 in. tubing. It is not bored-through and has no flow restrictor, making it a simple, inline coupling in linear piping. Cleaned and packaged to SC-10 standards, this part is cataloged under the Straights family of Swagelok tube fittings and carries the part number SS-1210-6. Typical applications include instrumentation and process lines where a reliable, two-ended 3/4 in. stainless connection is required for straight tubing runs, enabling straightforward expansion, maintenance, or reconfiguration of stainless steel piping networks.
