GN 441 Threaded Plug Aluminum Resistant up to 100° C

Threaded plugs GN 441 with the external diameter d1 match the screw-in holes for DIN 3852 pipe bolt connections. The sealing ring is embedded in a radial recess on the plane side, which makes the sealing ring captive and cannot be squeezed out during tightening. The sealing is also relatively soft, enhancing the sealing effect also on uneven surfaces.
