GN 741 and GN 742 Aluminum Fill/Drain Plugs

The latest products we'd like to introduce to you are our GN 741 and GN 742 Aluminum Fill/Drain Plugs, available with metric or BSPP parallel threads.

These RoHS-compliant plugs are made of turned aluminum with a matte shot-blast finish. They are available in plain, or with fill or drain symbol laser engraved. The GN 741 types have an NBR synthetic rubber seal, while the GN 742 versions have a seal of Viton rubber. The seal is retained in a groove undercut in the mating face, which prevents it from dropping out and from extruding when the plug is tightened. For this reason the seal can be of a softer material which offers better sealing.

Metric pipe thread sizes from M14 x 1.5 to M42 x 2.0 are available, as well as BSPP parallel threads from G ¼” to G 1½”.

You can explore our full line of Fluid Level Indicators and Components in Section 12 of our online catalog.
