Product description

Fasteners are an integral part of every flange connection. In order to achieve the necessary specific pressure on the seal, a sufficient axial force must be exerted by means of a bolt, bolt or threaded rod, which then ensures the deformation of the seal throughout its circumference and the resulting tightness of the flange joint.
