  • Fit standard 0.5cm tubing

  • No air leak or noise
  • Packed with 6 Pcs in total

How to Install

1. Before use, clean and dry the 2 ends of the tubing which is connected to the valve to ensure tight connection.

2. Check the right direction of the valve to make sure that it is consistent with the direction of air flow.

3. Insert the check valve into the tubing carefully and link them completely.

Tips: If the valve restricts air flow in both directions, please stick something into the hole on the inlet side of the valve to poke it open. And then the valve will allow for an unobstructed passageway for airflow.
