Swagelok SS-QM2-S-200 Miniature Quick Connect Stem, 316 Stainless Steel

Want to break and remake an instrument line in a single motion? The Swagelok SS-QM2-S-200 miniature quick connect stem lets you couple and uncouple with no twisting, no turning, and no wrenching. This is the stem half of the QM2 Series, machined from 316 stainless steel with a fluorocarbon FKM O-ring for dependable sealing. It carries a 1/8 in. Swagelok tube fitting end and a 0.06 Cv flow coefficient when coupled to a matching body. As a single-end shutoff (SESO) stem, it stays open when you disconnect, so remember that the stem side vents to atmosphere on uncoupling. You get a stout 4000 psig maximum working pressure at room temperature, which makes this stem a workhorse for calibration hookups, sampling loops, and instrument panels where you swap connections often. Keep system pressure at or below 100 psig at 70 F while you couple and uncouple. Pair it with a QM2 body to complete the connection.
