Sealing ring rubbers NBR (Perbunan)

Threaded plugs GN 741 are fitted with outside diameter d1 to suit screw holes with BSP threads to DIN 3852.

The sealing ring is bedded into a undercut groove which prevents it from dropping out and at the same time stops it from being extruded when tightening the cap.
