EheimEheim Tubing 594 Tubing 594 10Ft Tubing

Used it to replace old hard as a rock hose on my fish tanks. Fit like new and still holding tight after many months.

I decided to remove my co2 in tank diffuser to an inline diffuser because i got tired of the suction cups constantly detaching from glass, and i did not like the way it puts out the gas, too many bubbles in the water column.I run a fluval 407 canister filter and this hose locks in place perfectly at all connection points.The size is 16/22,Water is crystal clear, no more bubbles floating in the water column.

I'm not a fan of the ribbed hoses. My experience is they get more pinholes/leaks than high quality tubing. But I didn't see any replacement hoses for the Fluval 407. But then I came across the Pre-cut 16/22mm plastic hosing for Eheim. I saw one person said it worked and I figured it was worth a shot. Worst case, I end up with a flooded room. But when the Eheim hose arrived I confirmed IT'S THE PERFECT FIT! There is no decrease in flow and 0 leaks on any connection! So if you are looking to replace Fluval 407 stock ribbed hoses STOP LOOKING and invest in the perfect replacement!

The 594 tubing is for the larger ID connection parts.Eheim makes some high-quality products and parts.Yea there're somewhat more expensive but usually well worth it.

Very well-made product and fits on a filter I am using that is not from this company. It is a very snug fit on my canister filter (Fluval 207) fits well over an in-line heater, but was very difficult to get over my glass pipes. 16/22mm size that is if it matters.Only other issue I have is how stiff the tubing is. Any tight squeeze and it wants to start a little kink. All in all, I do recommend.

It's great tubing and the green helps hide the algae. If the ends are tight to get on just put them in a cup of hot water for a minute and they squeeze right on.

Good quality and so much better than those stiff ribbed hoses!

These were purchased for my Arium filtration system. Very flexible but yet sturdy. Hold a lot of pressure from my tank to my filtration system.
