Cleanroom tubing

An important product that Polyfluor supplies to the semiconductor industry is cleanroom hoses for high-purity applications. These hoses are made from PFA, PTFE, THV, FEP, PVdF and PUR materials, among others. A clean room is an extra clean room (in compliance with ISO 146441) in which certain operations are carried out under strict conditions. So-called secondary operations can additionally be carried out in these different classified spaces. Polyfluor supplies hoses in rolls, or cut to size, straight lengths or shaped. All produced, cleaned and packed. This applies not only to the semiconductor industry, but also to the medical industry and pharmaceuticals. This blog explains the importance of these hoses and what their use and application.


Cleanroom hoses unburden the customer because they prevent contamination in their clean environment/application. This means that our customers do not have to perform any additional actions to keep the hoses clean.


The cleanroom hoses are used in machines that make microchips to transport ultra pure cooling water and very clean gases. Any contamination in the tubing could potentially cause problems or delays in the chip production process. Another process is the cleaning of the wafers in the chip machine. This is done using ultra-high chemicals that are in large storage tanks. UHP PFA hoses are used for the transport of such chemicals. If contaminants get into those chemicals, the boards, or wafers, are not cleaned properly. As a result, the wafers can no longer be used in the machines.

The fact that cleanroom hoses are used in these machines is of great importance to the customer. Also, in the medical industry and pharmacy it is very important that clean hoses are used, for example for filling medicines or for the assembly of catheters. We have to make sure that our hoses are as clean as possible and meet the highest purity requirements. 

The cleanroom hoses are of course produced through a highly controlled process. Our high-purity PFA hoses comply with the SEMI57 standard. We have the customer’s preferences in mind, and deliver the hoses with or without laser marking for correct identification. We also supply black hoses with special pigment to block UV and our cleanroom hoses are available in many different metric and imperial sizes. You can also contact us for 2D and 3D shaped hoses, whether or not these are packed in a cleanroom and/or cleaned. Are you looking for more information? We will be happy to advise you and talk to you about the various possibilities.
