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

The Yor-Lok fitting is also known as an instrumentation fitting. It has 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.
