and then mechanical pull to complete the set. The Premium is for high pressure and temperature

while the Lite sustains moderate temperature and pressure. The need for a mechanical setting tool

does not exist because the setting mechanism is built-in. A ball is placed in the tubing string plugging

off the built-in equalizing ports. Pressure is then applied to set the top slip and then mechanical pull

is applied to finish the set. Releasing the tubing string from the plug is done by simply turning to the

right. Full tubing I.D. is available after releasing from the plug allowing other equipment to extend through

the end of the tubing string.
