The 70 series connector is used for external connections to flared, beaded, expanded, barbed and formed tube ends. It can be used to quickly and leak free connect to a test product. These connectors make sure that a test product and the leak testing equipment have a safe, leak free and secure connection. We can supply a connector with a pneumatic and sleeve functionality. A LED functionality or green positioning ring are also optional. Contact us for support on the best connector for your situation!
