Not sized for the larger hose barbs used on some skimmer or reactor plumbing — check your fitting size before ordering. Aqua Medic doesn't publish a maximum working pressure for this hose, so we can't confirm it against a specific regulator's output pressure.\u003c\/p\u003e\n\u003ch3\u003eCare and maintenance\u003c\/h3\u003e\n\u003cp\u003eTrim to length with a sharp blade for a clean, leak-free push-fit.

Check the fitting size stated on your other CO2 components first.\u003c\/p\u003e\n\u003ch4\u003eIs this hose gas-tight for CO2?\u003c\/h4\u003e\n\u003cp\u003eAqua Medic sells this as a CO2 line, but doesn't publish an independent gas-permeability or working-pressure figure for it, so we can't give you a number here. For a long-term, low-loss run, keep joins tight and check the line periodically for CO2 loss — a drop in bubble count at the same regulator setting is usually the first sign.\u003c\/p\u003e\n\u003ch4\u003eCan I use it with a check valve?\u003c\/h4\u003e\n\u003cp\u003eYes — it's designed to connect standard 4\/6mm CO2 components including check valves, in-line diffusers and solenoids.\u003c\/p\u003e","brand":"Aqua Medic","offers":[{"title":"Default Title","offer_id":55285029830947,"sku":"AB71614","price":27.95,"currency_code":"AUD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/7236\/5347\/files\/aqua-medic-silicone-co2-hose-10278090244387-1-dq.webp?v=1790372666","url":"https:\/\/nicksaquariumoceanariumterrarium.com.au\/products\/aqua-medic-silicone-co2-hose-4-6mm-5mtr-pack","provider":"Nicks AOT","version":"1.0","type":"link"}
