Description

Schego Airline Non-Return Valve (Pack of 2 qty) — Provides vital back-siphonage protection for aquarium air pumps and air accessories

The Schego Airline Non-Return Valve 2-Pack (SKU: SH652) provides vital back-siphonage protection for aquarium air pumps and air accessories. Installed in-line along standard airline tubing, it allows air to flow freely into the tank while blocking water from back-siphoning into the pump during power outages. High-quality airline non-return/check valve. Stops the backflow of water from the aquarium into the air pump during power outages.

Constructed with high-precision internal seals, these valves safeguard delicate electrical air pumps against short-circuiting and water damage caused by reverse water pressure.
