3/16" Professional Flexible Airline Tubing Standard Aquarium Air Pump Accessories, 20 Feet(Clear-Black)

Much more flexible, but makes a great seal with the gasket. Some other airline tubing can be difficult to remove from the gasket after a while as the plastic hardens, but this product is extremely well fit for purpose. You pay a little more but it is well worth it as you can use it again and again in a variety of applications.

Nice and supple tubing, the black looks good in my darker planted tanks. It grips the air stone and the check valve well, and doesn’t pop off like some of the more rigid tubing tends to. The extra suctioning cups are handy.

While the hose is preforming well, the suction cups don't. They no longer stick to the glass, they are stiff and no longer flexible. They haven't been in the tank for years (only a few months). Otherwise, everything else works well.

I am new to the fish keeping hobby, but I have purchased many products and supplies and even away from the aquarium, I am very impressed with the product in every way.1. packaging. the care and detail used in creating a product that provides everything it claims is impecible. and it was beautiful in its presentation.2. quality of materials. the tubing, the suction cups, even the filter to prevent water backflow to the pump...are all first class and more beautifully made than any I have seen.3. completeness. this kit provides all of the needed parts right down to custom inserts to bend the tubing around corners and to avoid decorations - it really was things I didn't think about until I tried to set up my tank.I can't believe I am reviewing this simple fish tank tube and parts, but it so impressed me that I felt compelled to talk about it to people considering buying it.I highly recommend this over other similar items that need to be bought individually and... when purchased in the package together it saves you alot of money. I suggest you try it.

Very nice air line, multiple uses, around the home like little rubber washers if you cut small sections. It is very flexible, stretchy, nice black that blends in very well with my black background tanks. Fittings work well too.

Soft material, no smell, easy to cut and connect as needed, easy to tie knots then get them out for acclimating new fish.

I purchased this for the assortment of pieces available, but especially the 90° elbow connectors to use with my existing air stone & sponge filter setup. The black airline tubing and the suction cup clips were a nice bonus to justify the cost. All of the connectors worked as expected... but I was SO surprised by the awesome quality of the airline tubing and the suction cups. I haven’t had them long enough to test their durability over time, but the whole kit was so easy to work with, I replaced all of my current tubing on my 46 gallon bow front with the new stuff from this kit. I may purchase it again just for the tubing, if I can’t find it sold separately. This purchase was such an unexpected & total win!

I just needed some air tube...or so I thought. This little kit had great reviews, so I decided to order it. IT'S GREAT! It includes so many little extras that I actually ended up using. Would definitely recommend it to anyone.
