Fasteners

An integral part of each flange connection is also the connecting material. In order to achieve the required specific pressure on the seal, a sufficient axial force must be exerted by means of a screw, bolt or threaded rod , which in turn ensures that the seal is deformed along its entire circumference and the resulting tightness of the flange joint.
