Blue rubber tubing

Blue rubber tubing

Blue rubber tubing is such a versatile product to be used in a variety of places, which includes virtually all industries, as well as everyday use at home. Blue rubber tubing is primarily made to serve for the transfer of gases, fluids and other various forms and substances. That is why it is primarily used in hydraulics, but also in all other industries such as the automotive industry, medicine and the like.

Due to its fantastic features, which include flexibility, resilience, tear-resistance, durability and many others, blue rubber tubing is also suitable for very harsh environments. These are environments where aggressive chemicals are found and where temperatures are very low or high. Different types of rubber are used to produce blue rubber tubing, but rubber as a material is generally known to be thermally stable, so whatever type of rubber you use, there are only small variations in the temperature it can withstand.

FKM withstands the highest temperature range without any damage. If you know that you will be using blue rubber tubing in an extremely hot or cold environment, then you can also order a custom, of the type of rubber that you think is most appropriate. The same goes for contact with chemicals, as some types of rubber stand out for their good chemical resistance.

Correct sizing is very important, so always pay attention first to the outside diameter, but also to all other size parameters. The outside diameter is the full cross section of the tube. What is more important is the thickness of the wall and the inner diameter, because it affects the flow of fluids, gases and more. The outside diameter affects whether the tubing will be able to fit, and the thickness of the wall affects the flow rate. Blue is not the only color available, but you can choose many different ones.
