Claims15
An electrical conduit system for use in a hazardous location comprising:
- a press coupler, the press coupler comprising:
- a first end portion and a second end portion;
- a first intermediate portion and a second intermediate portion;
- and
- a central portion;
- a conduit having a distal end positioned within the first end portion and the first intermediate portion of the press coupler;
- and
- electrical wiring provided through the conduit and the press coupler;
- wherein the central portion of the press coupler provides a stop for the distal end of the conduit,
- wherein the first end portion of the press coupler includes at least one projection that engages a wall of the conduit, and
- wherein a solid grounding connection is formed between the conduit, the press coupler, and the at least one projection.

An electrical conduit system for use in a hazardous location comprising:
- a conduit having a first end and a second end, wherein at least one of the first end and the second end includes external threads;
- and
- a press coupler, the press coupler comprising:
- a gasket;
- and
- a gripping portion, and
- wherein the gasket seals upon a vanishing thread of the external threads of the conduit when a diameter of the press coupler is compressed against the conduit.
4 more elements
An electrical conduit system for a hazardous location comprising:
- a conduit having a first end and a second end, wherein at least one of the first and second ends is externally threaded;
- and
- a press coupler, the press coupler comprising:
- a first end portion and a second end portion;
- a first intermediate portion and a second intermediate portion;
- a central portion positioned between the first intermediate portion and the second intermediate portion;
- a first gasket and a first gripping portion positioned within the first end portion;
- and
- a second gasket and a second gripping portion positioned within the second end portion, and
- wherein at least one of the first gasket and the second gasket upon a vanishing thread of the at least one externally threaded end of the conduit when the press coupler is compressed against the conduit,
- wherein the central portion provides a stop for the first end of the second end of the conduit,
- wherein a material hardness of the gripping portion is greater than a material hardness of the conduit,
- wherein the first end portion and second portions of the press coupler are a malleable material capable of compression, and
- wherein a grounding connection is formed between the conduit, the press coupler, and at least one of the first gripping portion and the second gripping portion.
