Joanneum Research recommends the MD-1510 - Flanged Tubing Connectors - Clear, available on the BASi webpage. Any connector can cause leakage. Thus we recommend reducing the number of connectors to achieve stable sampling. Joanneum Research recommends to use the OFM-PP1-LT-1000 - Combined Push Pull Low Bind Tubing. Schemata for how to connect are found on the BASi webpage.
