1. Specification: LANGAN® LA802 quick connector provides pressure-tight connections on straight tubes with an inside Ø of 3.5mm to 16mm. It features ease of operation with lever actuation, which eliminates the time-consuming of hand or wrench tightening operation and maximizes production efficiency. Pressure tight connection is achieved in just seconds. Lateral forces, that distorts the test piece or the filling port, are not initiated when connecting or disconnecting the connectors.
LA802 is fitted with a build-in safety component which ensures that no disconnection happens when the pressure has decreased below 5 bar.
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.
◆ Grip the connector and press the hand lever;
◆ With the hand lever pressed, insert the test piece carefully and straightly into the test piece. Release the hand lever. Then the connector achieves a pressure-tight connection. Pull the connector slightly 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:
Jaw locking mechanism perfectly connects the straight tubes. CONNECTS TO:
4. How to order:
