A simple one-way valve for aquarium air line, sold in a pack of two. Fitted between the air pump and the air stone, it lets air pass in one direction only and blocks water from travelling back up the tubing.
Without one, a power outage can allow water to siphon back down the air line. That can wreck an air pump, drain a tank, damage flooring and create a shock hazard, so a check valve is worthwhile on any air-driven sponge filter, air stone or protein skimmer feed.
Installation takes a moment: cut the air line somewhere between the air stone and the pump, then push the valve into each cut end, observing the flow direction.
Specifications: small and compact body; suits standard aquarium air line with 4 mm inner diameter; part number 10122; supplied as a 2 pack.
