1/4 ID Spring Band Type Clamps, Black, 40 Pcs

What problem we were trying to solve We needed reliable clamps for securing small hoses and tubing connections in automotive, plumbing, and DIY projects. These spring band clamps looked like a simple solution for creating tight, dependable connections without complicated installation. What actually happened when we used it The clamps were easy to install using basic tools and provided a firm grip on hoses and tubing. The spring design helped maintain consistent pressure, even when temperatures changed, reducing the risk of leaks. The assortment was useful for keeping extras on hand for repairs and maintenance projects. The clamps felt durable and held up well during regular use. The only minor drawback was that installation can be a little challenging in tight spaces. Pros • Provides secure hose connections • Maintains consistent clamping pressure • Durable spring steel construction • Easy to install and remove • Useful for automotive and household projects • Good value for the price Cons • Can be difficult to install in confined areas Who this is perfect for These clamps are ideal for mechanics, DIY enthusiasts, plumbers, and homeowners who regularly work with hoses and tubing. They’re especially useful for repairs, maintenance tasks, and keeping a variety of clamp sizes available for future projects.

I got the size I wanted

It was fast and what I ordered

These hose clamps cannot possibly fit over the 3/16" ID tubing I purchased---they are too small. According to my dial caliper, their maximum diameter is .212" (5.38 mm). My 3/16" ID tubing is .262" (6.65mm). Good luck with your tubing.

I bought the 10mm black ones. Out of the bag they measure about 9.9mm-10mm (.39 inches) in their free state. I used pliers to squeeze it as far open as I could 2 or 3 times and it did not break. However, it didn't return to its original size either. It now measures about 10.4mm to 10.7mm (.41 to .42 inches). Fully open is about 12.2mm (.48 inches). I also bought the 8mm (5/16") yellow zinc ones. They measure 7.9mm (.31 inches) give or take in the free state. Fully open is about 9.7mm (.38 inches). Again, the piece I tested did not break. After squeezing it now measures about 8.4mm (.33 inches). I would recommend that you don't squeeze them fully open if you can help it so that they don't stretch as much. I've got some 3/16" I.D. - 5/16" O.D. Oregon brand yellow fuel line. It measures about 7.9mm O.D. (.31 inches). If I use this tube on a barb meant for 3/16" I.D. tubing the 8mm spring clamp will probably be correct. If I stretch this tube over a barb for 1/4" tubing then the 10mm clamp will likely be the one to use.

Quick ship and good price on hard to find part in the local auto shops. Would buy from again no question!

Didn't fit for my purposes.

Excellent product.

good quality

Just fits on a Briggs and Straton gas line.

I ordered 10mm hose clamps and received 12mm hose clamps. They appear to be good quality clamps but I ended up ordering a kit of various sized hose clamps to take the guess work out of trying to get the proper size.

It is a hose clamp what can I say. They were well priced and I received in timely manner.
