## Description

Aquarium Air Pump Check Valves Red/Clear Clear Plastic One Way Non-Return Check Valve for Fish Tank

Review: Great quality check valves - Great quality check valves for a really reasonable price. Not much to these. Worked great for fixing my Keurig 2.0 K200 coffee maker which had a damaged air pump (very common problem I learned). Replaced the air pump and tested operation. Worked great but noticed water was being pushed into it, which is what caused it to fail the first time. Added one of these check valves in line and life is great now. Shame on Keurig for planned obsolescence.
Review: Great product for a great price! - Amazing value, works wonderfully! Gets the job done

## Features

- For Oxygen Pumps Only: Great 1-way check valve for most common aquarium air pumps. NOT suitable for CO2 or other high-pressure systems to avoid crack and leak.
- Small & Light: Size: 2.1" L x 0.55" W; Diameter of air holes: 0.12"; Weight: 0.1 oz. Standard ID airline tubing: 3/16". Add little weight to your hose for smooth airflow.
- Ideal Pump Protectors: Prevent backflow of water through the tubing during a power outage or pump pause. Essential accessories for basic aeration setup in your fish tanks.
- Sturdy & Quiet: Made of reliable plastic which can be tightly connected to the hose without air leak. The check valve can endure long-time use without making noise.
- Easy Maintenance: Clean the valve regularly. Please poke it with a slim stick from the inlet side to push it open when it gets clogged inside and restricts air flow.

Amazing value, works wonderfully! Gets the job done

### ⭐⭐⭐⭐ Works effectively but the hoses slip off over time.
*by B***H on July 13, 2025*

The airflow control works just fine but due to the smooth tapered connectors, the hoses constantly slide off. I had to superglue the hose onto it
