Model 407/408 2" Dedicated Well Head (#103872)
with Push-Fit Adaptors
Instructions
The Model 407/408 2" (50 mm) Dedicated Well Heads come with two 1/4" (6 mm) Push Fit Adaptors, so that either 1/4" (6 mm) or 3/8" (10 mm) tubing can be used for the sample return line. If 1/4" (6 mm) tubing is desired for the sample return line, simply push the Push-Fit Adaptors into the existing 3/8" Push-Fit Connectors until they seat (one Push Fit Adaptor for the top Connector and one for the underside).
To attach tubing just push into Push Fit Connector. To release tubing push down on both sides of the Top Ring and pull tubing out.
Note:
