A Pump-In Sub, also called High Pressure Flow Tee gives the ability to either pump into or bleed off wellbore pressure under high pressure. The Pump-In Sub incorporates a 2” high pressure quarter turn ball valve to allow rapid well control as well as a larger bore to pump in or bleed off the well bore. The Pump-In Sub also utilizes (but is not limited to) a 6K Guiberson style union for ease of use and capability of pressure.
