These straight unions connect two pieces of threaded RMC and IMC conduit together by screwing onto each piece. They’re suitable for use in hazardous locations where flammable gases, vapors, powdered metals, or dust is present.

These straight unions connect threaded RMC and IMC conduit to electrical boxes. One end screws onto the conduit, while the other inserts into the box and is held in place with a locknut. These unions are suitable for use in hazardous locations where flammable gases, vapors, powdered metals, or dust is present.

These unions connect threaded RMC and IMC conduit to electrical boxes on a 90° angle. One end threads onto the conduit, while the other inserts into the box and is secured with a locknut. These unions are suitable for use in hazardous locations where flammable gases, vapors, powdered metals, or dust is present.

These expansion unions screw onto the ends of two pieces of threaded RMC and IMC conduit and have a telescoping piston that extends and retracts to compensate for length changes of conduit. They’re often used where there are large fluctuations in temperature, which can cause conduit to expand and contract. These unions are suitable for use in hazardous locations where flammable gases, vapors, powdered metals, or dust is present.
