Installed in the 4\/6 mm CO2 line, it lets gas pass towards the tank and blocks water from flowing back towards the pressure regulator.\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cp\u003eWhen the CO2 switches off at night or the bottle runs empty, water can be siphoned back up the tubing and into the regulator or solenoid valve, where it causes corrosion. A check valve prevents that. Steel valves also don't turn brittle with CO2 the way plastic ones can.\u003c\/p\u003e\n\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eStainless steel\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eTubing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e4\/6 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCheck valve (non-return valve)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWeight\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eapprox. 10 g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eHow to install\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eCut the CO2 tubing between the bubble counter and the diffuser, close to the aquarium.\u003c\/li\u003e\n\u003cli\u003ePush both ends onto the valve.\u003c\/li\u003e\n\u003cli\u003eMake sure the engraved arrow points in the direction of gas flow, towards the diffuser.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDo I need one if my bubble counter has a check valve?\u003c\/strong\u003e\u003cbr\u003eA second valve close to the tank is a cheap insurance, especially with a solenoid valve that switches CO2 off every night.\u003c\/p\u003e\n\n\u003cp\u003eWorks with any CO2 system, including the \u003ca href=\"\/products\/me-co2-regulator-ultra\"\u003eMe CO2 Regulator Ultra\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eBrand:\u003c\/strong\u003e Me  |  \u003cstrong\u003eCategory:\u003c\/strong\u003e CO2 check valve\u003c\/p\u003e","brand":"Me Aquaristic","offers":[{"title":"Default Title","offer_id":63872315982154,"sku":"15m01269","price":9.99,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/3685\/5370\/files\/19_3_01048a5c-4174-474b-897b-bb30b5692d89.jpg?v=1791614319","url":"https:\/\/aquarium-boutique.com\/products\/me-co2-safety-flow-steel-stainless-steel-co2-check-valve-for-4-6-mm-tubing","provider":"Aquarium Boutique","version":"1.0","type":"link"}
