Metal Seal Fittings

Metal seal Fittings works on the principle of groove & tongue with depth of immersion less than 1mm without any intermediate seal. This principle guarantees permanent tightness at high stresses which results from vacuum & pressure in connection with high vibration & temperature inside the tubing systems.

Sealing is effected by direct contact of the sealing profiles of the groove and tongue parts. The different radii of curvature of groove and tongue are in a certain relation to each other. Thus, two ring-shaped sealing areas are produced which create high stability. The additional braking surface prevents plastic deformations at the ring-shaped sealing areas.

Metal seal fittings are easy to assemble and require no maintenance. They can be loosened and re-connected as often as desired. Thus, the re-use of the Metal seal Fitting is guaranteed. Due to the little depth of immersion of Metal groove and tongue the tubes can be immediately pulled out laterally after loosing the clamping nut.

High pressure tube unions equipped with the Metal seal principle can be used in many field of application, particularly where systems need to be revised frequently or where critical operating conditions prevail.
