Product Details
✓Includes 1 stainless steel check valve and 2 plastic check valves, and 2 extra suction cups.
✓Fits standard aquarium airline tubing with inner diameter about 4mm. However, the stainless steel check valve is suitable for PU hard tubing (e.g. Asin: B08YYRMZR3), the plastic check valve is compatible with any flexible or rigid airline tubing.
✓The stainless steel 1 way valve has a convenient quick-connection design that easily locks the inserted tubing and is not easily popped open, and push in collet to pull out the tubing in 1 second. It can be connected to both the tubing and CLSCEA's stainless steel CO2 diffusers (Asin: B08YXDXKLZ).
✓Exquisite workmanship and premium quality plastic check valves.
✓Stainless steel non return valve is suitable for CO2 system, HIGH PRESSURE resistant (up to 87Psi/0.6mpa). Plastic check valves can be used for LOW PRESSURE CO2 system and O2 system (air pump).
