Swagelok SS-1210-6-8 Stainless Steel Reducing Union, 3/4 in. x 1/2 in. Tube OD

Transition a 3/4 in. header down to a 1/2 in. branch in one solid, straight connection. The Swagelok SS-1210-6-8 reducing union joins two tube sizes inside a single 316 stainless steel body, so you change size without welding and without a stack of adapters. Swagelok's two-ferrule grip seats each tube, seals it gauge-tight, and lets your crew inspect the pull-up before the line ever sees pressure. This union carries the load on larger process runs, utility lines, and supply headers where flow steps down to feed instruments and smaller branches. Fabricators trust it because it makes up fast, holds firm under vibration, and remakes cleanly during maintenance. The heavy 316 stainless build stands up to corrosive media and the hard-service conditions of refineries, chemical plants, and power stations along the Gulf Coast. When your line needs to drop from 3/4 in. to 1/2 in. and stay leak-free, reach for this union. Collins-Oliver stocks Swagelok straights in Baton Rouge. Call for your quote.
