The Conex Equal Cross by Prevost is a four-way push-to-connect fitting that joins four tubes of the same outside diameter at a central junction. Each port uses the Conex push-in mechanism, so tubes seat with a firm push and are held by a stainless steel grab ring and O-ring seal, with no threading or tools required.An equal cross is useful where an air line needs to branch in several directions, such as feeding multiple drops or tools from one point. It belongs to the wider range of Conex connectors and other push-to-connect fittings that make compressed air assembly fast and repeatable, integrating cleanly into an aluminum air piping system.
