The connection principle used in Series 2M has been developed for thin pipes, e.g. capillary tubes of 0.7 to 6.35 mm outside diameter. The connector consist of a sealing cone which is pushed into the matching inner taper of the connector to act as a bushing for the pipe while performing a sealing function. An additional O-ring, which is protected against damage by a pressure disc, holds the pipe in place and prevents it from being pulled out accidentally. The result is a secure and tight connection.
