MPX Connectors

See MPX Products

MPX Series Connectors make it easy to quickly connect-disconnect and transfer fluid or media anywhere in your process. Simply push the two halves together to connect, and disconnect by pressing the thumb latch to separate. To protect the lines before and between transfers, caps and plugs are available for sealing off disconnected halves and optional locking sleeves are available to prevent accidental disconnects. Coupling halves can be rotated while connected to reduce tube kinks. The MPX offers additional flexibility when changing to a larger tubing size, with the Back-to-Back adapter connecting to the MPC product. Choose from a full line of male and female MPC connectors and configurations, in sizes to fit 1/2", 3/8" and 3/4" tubing. For a quick connection rely on the MPX series connectors.
