1. Specification: LANGAN® LA-FE automated quick connectors for leak test achieve instant, leak free connections for pressure and vacuum testing, fluid filling and flushing. It seals tubes and hoses reliably and quickly.
Fitted with elastic seals, the LA-FE is ideal for sealing round and rough surfaces as well as the test pieces with wide tolerance ranges. Thanks to the pneumatic acctuation, the connector is particularly well suited for automation of test procedures. The connector doesn't apply axial force or lateral force on the test piece.
2. Operating instruction:
Please strictly follow the operation steps. Improper operation can cause poor sealing, leakage and risk of connection failure resulting in damage or injury. Do not disconnect the connector while under pressure. Damage or injury may occur.
◆ Secure the quick connector with a suitable fixturing device. Carefully place the connector straight into the test piece;
◆ Apply pilot pressure to the connector. Then the connector achieves a pressure-tight connection.
◆ Apply the required test pressure to media inlet to start the test process.
◆ After the end of the test process, vent the media line completely. Make sure to depressurize the connector before releasing the connection.
◆ Depressurize the pilot pressure line.
◆ The connector can be removed straight backward.
3. Application Type：
Pneumatic actuation connection quick connector is used in automated process.
