GN 441 Threaded plugs Aluminum, with Finger Grip, With NBR Seal


GN 441 Aluminum Threaded Plugs with Finger Grip with NBR Seal

Product description


GN 441 threaded plugs have an external diameter d1 matching the screw-in holes for DIN 3852 pipe bolt connections.

The seal is embedded in a radial recess on the plane side, which makes the seal captive, so it cannot be squeezed out during tightening. The seal is also relatively soft, enhancing the sealing effect even on uneven surfaces.

For version with VITON® seal, see GN 442.
