1. Description: LA300L quick connector features longer length of the thread on the connector.
LA300L quick connector features the design of changeable actuation method. It has two forms of actuation including lever actuation and thumb valve button actuation, which allows the operator to change the method of actuation by simply unscrewing the rear portion of the connector and replacing it with other form of actuation.
2. Operating instructions:
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.
◆ Press the hand lever;
◆ With the hand lever pressed, insert the connector straightly into the test piece until the front seal contacts the test piece. Release the hand lever. 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:
LA300L quick connector is an ideal tool for internal threaded applications. It is suitable for testing engines, cylinders and valves.
