Union Type 780 with Flameproof Ex d IIC & Increased Safety Ex e II forms of protection

The CMP Type 780 Metallic Union is designed to allow connection of rigid and flexible conduit, or terminated cable glands, to any fixed equipment.

The 780 Union provides a running connection by means of an integral coupling arrangement that eliminated the need to rotate the conduit, or cable, or equipment to achieve a correct termination. The ease of installation offered by the 780 Union consequently makes the process of removing the conduit or other terminated cable entry devise from the equipment a simple, fast and effective one.

These Unions are approved for use in conjunction with Ex d and Ex e certified equipment and cable entry devices, and can also be supplied with thread conversion between the forward and rear threads to either a reduced size or a variety of different thread types, e.g. Metric to NPT, or NPT to Metric.

A general purpose Industrial version is also available
