Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

The fittings are also known as an instrumentation fittings. They have two sleeves (double ferrules) that bite into metal tubing for a strong seal.

To maintain the temperature of liquids as cold as -325° F, this hose has vacuum insulation and a reflective barrier. This prevents heat transfer in the same way a thermos does, so the exterior of the hose won’t freeze or form condensation. Thread the fittings on this hose onto a freezer or other equipment in your plant or laboratory.

These fittings are made to tighter tolerances than other stainless steel pipe fittings. They are also known as instrumentation fittings.
