1. Specification: LA800 quick connector for leak testing instantly connects to copper, steel and aluminium straight tubes. LA800 quick connector is suitable for vacuum testing, function testing, underwater testing and helium testing.
The connector is equipped with an internal safety lock component which prevents accidential disconnection under pressure. The sealing system ensures the duribility and excellent leak-tight test performance of the connector.
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.
◆ Insert the test piece straightly and carefully into the test piece. Make sure that the connector is inserted to the required minimum insertion length (refer to the ordering chart below);
◆ Rotate the hand lever by 90° downwards or upwards. Then the connector achieves a pressure-tight connection. Pull the connector lightly to make sure that the connector is firmly connected in place.
◆ Apply the required test pressure to media inlet to start the test process;
◆ At the end of the test process, vent the media line completely. Make sure to depressurize the connector before releasing the connection;
◆ Actuate the lever and pull the connector straight back to disconnect the connector with the test piece.
3. Application:
Instantly connect and disconnect for sealing on straight tubes. Main applications of quick connectors are vacuum testing, pressure testing and helium testing etc.
