Dimple-on x Dimple-on connectors are used to connect two sections of coiled tubing using a stronger connection than a regular Roll-on. The Dimple-on x Dimple-on connectors are available in a wide variety of configurations, and can be customized to meet your specifications. A specifically sized bushing along with a yoke (installation tool) and hydraulic pump are used to secure the connector to the coiled tubing.
