Package List: 1 x Pneumatic Manifold Air Distribution Block Note: 1. Do not unplug and insert the air pipe frequently during the use of the connector, which will affect the service life of the connector and air pipe.2. The pipe inserted into the joint needs to be inserted to the bottom of the joint to avoid the possibility of air leakage.3. When pulling out the air pipe, first confirm that there is no pressure in the tube, press the end cap of the joint to the end and pull out the air pipe.
