Getting a Grip on Strong Seals

J.W. Winco now offers its GN 441 and 442 Series threaded plugs not only with finger grips, but also relatively soft seals to enhance sealing on uneven surfaces.

J.W. Winco now offers its GN 441 and 442 Series threaded plugs not only with finger grips, but also:

  • A relatively soft seal embedded in a radial recess on the plane side, which makes the seal captive, so it cannot be squeezed out during tightening, and enhances the sealing effect even on uneven surfaces.
  • Aluminum plug bodies, with either a tumbled matte or black plastic-coated finish.
  • An NBR synthetic rubber seal (for the GN 441) or a VitonĀ® seal (for the GN 442).
  • An easy-to-turn profile as a result of the finger grip.
  • A range of sizes with metric or BSPP parallel threads.
  • An external diameter matching the screw-in holes for DIN 3852 pipe bolt connections.
  • Availability with or without a vent hole.
  • RoHS compliance.
  • An optional dipstick upon request.
