Original Press Release

J.W. Winco, Inc. Offers Aluminum Fill/Drain Plugs

Press release date: April 18, 2014

NEW BERLIN, WI – J.W. Winco, Inc., a leading supplier of standard industrial machine components, announced it now offers GN 741 and GN 742 Aluminum Fill/Drain Plugs with metric and 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 ½”.

J.W. Winco offers an extensive selection of inch and metric size adjustable levers, cabinet U-handles, plastic and steel hinges and locking mechanisms, revolving and retractable handles, hand wheels, hand cranks, tube connection and conveyor components, inch and metric construction tubing, shock absorption mounts, leveling mounts, hand knobs, spring, ball and indexing plungers, jig, fixture and fastening components, retaining magnet assemblies, toggle clamps, metric casters and wheels, universal joints, oil sight glasses, and metric tools for the industrial and commercial equipment industries.
