Union Connector

DMfit metric union connectors join two tube runs in a straight connection. Choose an equal union when both tube ends have the same stated size, or a reducing union when the two ends differ. Each product name shows the sizes of both connections, so compare both before ordering.

For example, a 10mm x 10mm union connector has two 10mm tube connections, while a 10mm x 6mm union connector lists different sizes at each end. If the tube route also needs to turn, browse metric tube elbow unions. For inch-sized tubing, see the imperial fittings range.
