  • Sturdy tubing that doesn’t kink
Size: 25 Feet Style: Plastic
This tubing is built really well—much sturdier than the flimsy kind I replaced. It doesn’t kink, and because it’s slightly stiff, it connects easily, doesn’t leak, and stays securely in place. At the same time, it’s still flexible enough to work with and get the job done. Solid quality and exactly what I was looking for. ... show more

  • Basic airline tubing
Size: 8 Feet Style: Plastic
Standard airline tubing. I had a bit of struggle attaching it to the outlet on the pump (the tubing is quite stiff) but it worked just fine once I secured it in place. Reasonable priced. Fast shipping.

  • Does it’s job, but…
Size: 25 Feet Style: Plastic
The tubing does it’s job well. I run sponge filters off of a Top Fin air pump. The tubing, however, was extremely difficult to fit over my air pump output, my check valves, and my sponge filter. In comparison to the brand of tubing I used before, this one had a way smaller inner diameter. I had to hold the tubing under hot water for a while in order to jam it over the outputs. The price can’t be beat and the tubing works great after the initial struggle, but if you don’t mind spending a few more cents for ease of use, pick a different brand. ... show more

If you’re the proud parent of a Labubu or other plush pendants, this stuff is great to keep your plush from slipping off your bag or getting stolen.

  • These are good for anything aquatics.
Size: 25 Feet Style: Plastic
Came as expected and on time. Thank You! these hoses are good for acclimating new fish. Take a strand of Hose from your aquarium into a 5 gallon bucket, put your fish in the bucket in the same water they come in. Your tank water will acclimate to the water there in and it'll cause less stress than it does when floating ... show more
