212 Stinger Wellhead Assembly
The 212 Stinger Wellhead Assembly allows installation of a 1” stinger within vapor extraction wells with a well casing inside diameter of 4” and is used in conjunction with the stinger variant of the 212 Total Phase Extraction Control Assembly (sold separately). The wellhead assembly contains a 1” diameter drop pipe hole for stinger installation, a 3/4" plug which can be removed to take a fluid level measurement (alleviating the need to remove the wellhead assembly), and a 1/4" ball valve assembly for measuring the vacuum within the wellhead. Additional wellhead assembly sizes are available by request.
