The non-return check valves can effectively prevent water from back siphoning and ensure smooth airflow. Necessities in the house of aquatic lovers.

Key Features

• ✅ For Oxygen Pumps Only: Great 2-way check valves for most common aquarium air pumps. DO NOT use them in CO2 or other high-pressure systems to avoid cracking or leakage.
• ✅ Small & Light: Size: 2" L x 1.42" W; Weight: 0.25 oz; Airline Tubing: 3/16" standard ID tubing. The air pump valves add no weight to the hose, allowing for smooth airflow.
• ✅ Ideal Pump Protectors: The aquarium air valves can effectively prevent water backflow during a power outage or pause of the pump. Ideally protect your pump and reduce your loss when you’re at work or on vacation.
• ✅ Reliable Material: Made of sturdy plastic, the non-return valves can be tightly connected to the hose without air leakage or obstruction. Dependable for long-time use.
• ✅ Detachable Design: Easy to detach it for cleaning and maintenance without using tools. Please stick something into the hole to poke it open when it gets clogged and restricts air flow.
