The Marina one way valve, also known as a check valve is designed to fit 6mm airline.
Protecting your pump from damage by back-siphoning, which can happen if you lose power to the air pump during a power cut or if it is switched off. This is the most common cause of faulty air pumps.
These non-return valves are low resistance, which will not affect the air flow to your aquarium, and they are very easy to install anywhere along the airline. Just cut the airline and push the airline over the 2 smaller ends of this valve. This will protect and prolong the life of your airpump.
