Model 407/408 Dedicated Well Head
407/408 Dedicated 2" Well Cap Assembly (#110227)
The Dedicated 2" (50 mm) Well Cap Assembly comes with three 1/4" (6 mm) Push Fit Adaptors, so that either 1/4" (6 mm) or 3/8" (9.5 mm) tubing can be used for the sample return line or drive line.
The Assembly also comes with three red plugs that can be used to keep debris out of the sample line and access hole when not in use.
If 1/4" (6 mm) tubing is desired for the sample return line, simply push the Push Fit Adaptors into the existing 3/8" (9.5 mm) Push Fittings until they seat (one Push Fit Adaptor for the top fitting and one for the underside). If 1/4" (6 mm) tubing is desired for the drive line, simply push a Push Fit Adaptor into the existing drive line fitting on the underside.
To attach tubing, just push into the Push Fit Connector. To release the tubing, push down on both sides of the top ring and pull the tubing out.
