Under flowing artesian conditions or for vapour sampling, the CMT Multilevel System can be fitted with a flow through seal assembly (Figure 22) to allow the user to collect a sample, measure hydraulic or pneumatic pressure, and prevent uncontrolled flow from the well.

The flow through seal assembly is tightened using a 11/32″ (9 mm) spanner. Once tightened, press down on the black ring while pulling up to remove the red plug. Then push the 1/4″ OD tubing into the fitting, which creates a leak-proof seal.
