Profile: WEH Technologies Inc. specializes in developing and designing special test connectors for leak testing. TW17 connector for pressure & function tests on components with internal threads is designed for sealing internal thread applications. The higher the test pressure the tighter the connector clamps itself into the thread of the test piece. The front O-ring reliably seals the connection. No additional clamping devices are required. Time-consuming and expensive testing devices are eliminated. The connector is available with different actuations. Our test connector type TW710 has been specifically developed to connect fuel lines for engine hot testing. The short design of the connector is best suited for narrow spaces and meets the demand of such application. The fuel connector TW710 is equipped with a lateral test port for ease of use and can be connected to tubes with bead, collar or external thread. An integrated shut-off valve prevents leakage of fuel and enables a clean & safe operation. Quick coupling TW141 provides pressure-tight connections on straight tubes and has earned a reputation for ease of operation. W141 is a lever-actuated connector for quick connect and quick disconnect, which creates no lateral forces that can distort the test piece or fillling port when connecting and disconnecting. The TW141 is fitted with an internal safety feature which prevents the connector from being removed until a pressure lower than 5 bar is attained.
