On/Off Tool

The Thermal Grapple Connector is a high temperature connector for coiled tubing. The connector incorporates a versatile design that can be fitted for all sizes of coiled tubing and threaded connection. Sealing is accomplished using a high temperature graphite seal rated for temperatures up to 500°C. The sealing and slip components are independent in function allowing the operator to have better control over installation. The connector can be used for well interventions or for life of well sealing integrity.
