PTFE Hoses: They Are Everywhere
For over 60 years now, Polytetrafluoroethylene, or PTFE as it is better known, has been recognized as a unique material with many rare qualities evoking its usage in literally every branch of industry in modern times. PTFE is frequently used to coat non-stick pans and cookware. It is commonly used as graft material in surgeries, and as a lubricant in large-scale machinery.
Another one of the many uses of PTFE is to make hoses. The qualities of PTFE making it ideal for hoses of all shapes, sizes and purposes are its resistance and self-cleaning traits. PTFE hoses boast an unparalleled chemical resistance, as there are very few substances in the world that can penetrate or even affect the strength of PTFE. Additionally, PTFE hoses maintain a strong resistance to temperature, weather and aging, completely hampering any degradation in temperatures from -94°F up to 500° F (more extreme temps with additional sleeves for high heat and cryogenic transfer) Foreign substances do not attach or stick to the lining walls of PTFE hoses either, making PTFE hoses virtually self-cleaning. Since PTFE hoses maintain such a high sanitary standard they are frequently used in the manufacturing of pharmaceuticals, cosmetics and food & beverage. PTFE hoses are also widely used for hot oil, chemicals, acids, adhesives, paints, steams, solvents, and more because PTFE hoses are the most versatile, clean, and durable type of hoses available.
There are several varieties of PTFE hoses, used for a range of purposes. PTFE hoses without braids are designed for low-pressure use or unpressurized uses. They are available in two versions: corrugate or smooth bore. Non-braided PTFE hoses are used more frequently in industrial applications surrounding food, laboratory and pharmaceutical applications. Both the smooth bore PTFE hoses and the convoluted PTFE hoses with stainless steel reinforcement are used widely in all industries. But the highest quality PTFE hoses are designed for reloading of very aggressive chemicals, pharmaceutical and food products and represent the most demanding applications.
