Aluminium plugs have magnetic properties

JW Winco now offers aluminium threaded plugs with NBR seals and magnetic stems.

JW Winco now offers aluminium threaded plugs with NBR seals and magnetic stems.

These magnetic plugs are made of aluminium with a matte shot-blasted finish and laser-engraved symbols.

The magnetic stem attracts iron particles that might be suspended in the liquid.

The stem is of a length that makes it impossible to demagnetise itself.

The seal is of NBR synthetic rubber with a maximum heat resistance of 120C.

The seal is retained in a radial undercut in the mating face, preventing it from dropping out or from protruding when the plug is tightened.

The design allows the seal to be made of a softer material, which offers better sealing.

Plugs are available in metric pipe thread and BSPP parallel threads, and versions with Viton seals are also available.
