These ferrules are standard for all fittings and valves on the market using UPCHURCH SCIENTIFIC®, VICI® compatible fittings. An AFP® metal ferrule does not create a restricted ID when they swage on the tube thus preventing a release at high pressure. They cut a ring near the end of the tube fit-in, so this way the ferrule stays in place on the tube. This usually takes only about 1/4 turn beyond the point where the ferrule
first starts to grab the tubing. AFP® ferrules may be used with all AFP® fittings and with those from other manufacturers. The maximum pressure limit is generally determined by the yield strength of the tubing. The maximum pressure for softer materials (such as brass) is lower, and it depends on the tubing used. If you have doubts about a particular combination, consult our technical staff.
They are generally made of stainless steel 316 L, an Austenitic stainless steel that is used in most chromatographic applications. We can also offer some of them in a variety of materials.
