The curved 304 stainless steel pipe carries your CO2 line cleanly over the rim of the aquarium, so there is no soft tubing kinking or sagging across the glass, and the built-in quick-connect check valve helps prevent water from siphoning back down the line into your diffuser, solenoid or regulator when the CO2 shuts off.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eIt is made from 304 stainless steel for long-term corrosion resistance, with a polished finish that stays discreet on a rimless or rimmed tank. The check valve uses a push-to-connect quick fitting with a directional flow marking, so it installs in seconds and there is no doubt about which way it goes in the line.\u003c\/p\u003e\n\u003cp
