1. Description: LA300 pressure, vacuum and function test quick connector is used for female threaded components. The higher the test pressure, the tighter the connector will clamp itself onto the threads of the test piece. It establishes a pressure-tight connection in seconds.
Special versions (custom leak test quick connectors), e.g. longer or shorter versions, plug versions etc. are possible.
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:
LA300 quick connector for hydraulic oil leak test is suitable for leak testing of engines, tanks, pumps, oil cooler and new energy E-mobility etc.
