It’s available in two connection types to suit different setups: Air Line is designed for standard 4\/6 mm air line tubing, ideal for use with air pumps or low-pressure CO₂ setups. CO₂ connects directly to CO₂ regulators, needle valves, or splitters — perfect for pressurised planted tank systems. The integrated stainless steel check valve adds an essential layer of protection, helping prevent water from entering your regulator or pump. With its durable metal housing and transparent chamber for bubble counting, this tool is a practical upgrade for any aquarium gas system.\u003c\/p\u003e\u003ch2\u003e\u003cspan style=\"color: rgb(53, 152, 219);\"\u003eBenefits\u003c\/span\u003e\u003c\/h2\u003e\u003cul class=\"a-unordered-list a-vertical a-spacing-mini\"\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003eDual-Function Design: Combines a precision bubble counter with an integrated stainless steel check valve for added protection.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003eSturdy Metal Construction: Durable metal body resists pressure, cracking, and wear over time — ideal for long-term use.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003ePrevents Water Backflow: Built-in check valve protects your air pump or CO₂ regulator by stopping water from flowing backward.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003eTwo Connection Types Available: Choose between air line tubing or direct-to-regulator models to suit your aquarium setup.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"a-spacing-mini\"\u003e\u003cspan class=\"a-list-item\"\u003eCompact and Easy to Install: Simple inline design fits neatly into your existing air or CO₂ system with no tools required.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003e\u003cspan style=\"color: rgb(53, 152, 219);\"\u003eDirections\u003c\/span\u003e\u003c\/h2\u003e\u003cp\u003eEnsure correct style is selected\u003c\/p\u003e","brand":"vendor-unknown","offers":[{"title":"Air","offer_id":57690259652933,"sku":"82401","price":12.99,"currency_code":"GBP","in_stock":true},{"title":"CO2","offer_id":57690259685701,"sku":"82402","price":12.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1043\/1551\/9301\/files\/finest-filters-airline-or-co2-bubble-counter-check-valve.png?v=1776203565","url":"https:\/\/finest-filters.co.uk\/products\/2-in-1-metal-bubble-counter-check-valve","provider":"Finest Filters","version":"1.0","type":"link"}
