Fittings

Double Ferrule Type Tube Fitting

Mechanical fittings with two ferrules

By simply tightening the nut, the back ferrule holds the tube and the front ferrule seals the fluid. Wetted parts are all made up of the same material, which means various fluids over a wide temperature range can be firmly sealed.
*Stainless products are RoHS compliant.
