Swagelok 6LV-8MW-6-4 Micro-Fit Union Fitting

The Swagelok 6LV-8MW-6-4 Micro-Fit Union Fitting is a 316L VAR (VIM-VAR) stainless steel reducing union that connects a 1/2 in outer-diameter tube to a 1/4 in outer-diameter tube. Designed for Micro-Fit tube fittings in ultrahigh-purity fluid systems, it provides a compact inline transition with reliable leak-tight performance in demanding chemical processing, pharmaceutical, and semiconductor environments. The part is built from 316L VIM-VAR stainless steel and forms a true Micro-Fit union reducer, enabling robust connections within tight instrumentation and process piping. Swagelok catalogs identify 6LV-8MW-6-4 as a 1/2 in to 1/4 in Micro-Fit union reducer, part of the Micro-Fit family that supports miniature tube fittings for clean, high-purity applications.
