STAINLESS STEEL CHECK VALVE for CO2 & AIR PUMP AIR LINE TUBE

This high-quality stainless steel check valve regulator is excellent for ensuring CO2 gas or air from oxygen pump flows in the correct direction to avoid accidental backflow which can damage your equipment and prevent fire hazards.

Made of stainless steel.

Fits standard 4mm internal diameter 6mm external diameter aquarium airline. 


DIFFERENCE OF HIGH QUALITY METAL VS CHEAP PLASTIC VALVE CONTROL

1) NO LEAKAGE

Do note that the common plastic airline control valve always leak air out from its screw part as it lacks O ring and because of its cheap plastic construction, unlike this high quality stainless steel check valve.

We have tested this by comparing the cheap plastic type VS this high quality metal type for CO2. When we put soap bubbles (soap bubbles are standard to test for air leakage) around the screw part of the plastic type control valve, we can see a lot of external soap bubbling which indicates external leakage of air from the cheap plastic type. But when we do the same test on this high-quality metal type control needle valve, there was no external bubbling at all which means there is no external leakage.

2) ASTHETIC

This stainless steel check valve looks sleek and modern, unlike cheap plastic check valve.

3) DURABILITY
The metal type can easily lasts over 10 years or even a lifetime. It does not suffer issues which affect plastic like wear and tear of the plastic thread as the tube is put on and removed, weakening from exposure of UV from light/sunlight, etc.
