Mueller/ B&K ' 1/4" OD X 50´' Refrigerator Tubing

I needed this copper tubing to replace the plastic poly tubing I have been using for our swamp cooler. I've used several brands of poly over the years that all break in 1-3 years because it is exposed to the sun on the east side of our house all morning. I PROMISE, I PROMISE I will blow this copper out with the compressor when I shut down the cooler every fall! Hopefully it will last for many years this way. This tubing will also work well for anyone who has an ice maker in their refrigerator and is dubious about using plastic hose to supply it or who has already had a problem with plastic hose leaking or breaking. Small copper tubing like this is rather "tender" and liable to get kinked, bent, or dented in shipping. This vendor carefully wrapped the coil of tubing in heavy cardboard, so it shipped safely from New York to Washington state - KUDOS!

I like it, it's quality and works fine

This copper tubing seems fine.

This is a fantastic product for the primary on a Tesla coil. It molded easily and with a few zip ties and some little hands to help pose it we made a nice concave coil to transfer and amplify ultra high voltage electricity wirelessly to the secondary. R.I.P. to the wild Green Anole that found it's way onto the primary on Halloween. He was crispy as a tortilla chip when I found him the next day. Would definitely recommend for primary coil build.

The tubing that I received was labeled Carnot. It worked just fine for my swamp cooler and I saved twenty dollars by getting at Amazon.

Much prefer over the poly line. Easy to work with and stays in place with far fewer mounting points. Easy to shape and fit and feels thick enough to last. Good product.

Good quality tubing, easy to work with and clean.

Came open and was not B&K, but still ok for my purposes, a swamp cooler line that won't hopefully break/leak.

Arrived in good shape with both ends capped off. Clean and in good condition
