Series:Tube Fitting-Straight Reducing Unions-
Model:Fractional Tube
Fd-lok compression fittings are interchangeable with Swagelok fittings.Fd-lok back ferrules are all carburizing treated,which makes the ferrules impress on the tube tightly to make a leak-proof connection. Fd-lok nuts are silver plated to minimize the friction with the body threads.Fd-lok reducing union features in:
1. Sizes range from 1/16" to 1 1/2" and 2mm to 38mm
2. Different materials and configurations are available
3 Hardness can reach 700-900 HV.
4. Fittings are easy to disconnect and retighten.
5.Fittings are available in various materials, such as SS316, SS316L,MONEL 400,HASTELLOY C276, F51, F53, F55, INCOLLOY 625, 825 ETC.
