The THD Mechanical Service Packer is designed for general purpose high pressure service work. The THD uses keyed internal connections, allowing transmission of high torque through the packer facilitating rotation of the drill string in high angle holes. The hydraulically operated upper hold-down buttons anchor the packer with differential pressures from below. The packer has carbide trim buttons and slips for high strength casing and longer service life.
