Polyflon offers fluoropolymer tubing in three main styles: smoothbore, convoluted and corrugated. As standard, all types are available in coils; on spools or as straight cut pieces. We can supply such tubing precision cut; thermoformed or fabricated into various shapes and also assembled with many types of connector ready for immediate installation. Most tubing products are single bagged to maintain cleanliness but items can also be doubled bagged for extra protection. Cleanroom packaged tubing is available should the application demand it.
Although each fluoropolymer material enjoys a particular individuality with regard to material properties, there are clearly common attributes that run though all fluoroplastics: excellent chemical resistance; superior temperature performance and inherent purity. If you are unsure as to which material is the right fit for your application the table below should help to begin the process of material selection. More refined information on specific tubing materials can then be obtained using the fluoropolymer tubing navigation column to the right.
