What is Stainless Steel Braided PTFE Hose?
Stainless steel braided PTFE hose is a type of hose that combines the non-stick properties of PTFE with the strength and flexibility of stainless steel. PTFE, or polytetrafluoroethylene, is a synthetic fluoropolymer that is known for its non-stick properties and high temperature resistance. Stainless steel, on the other hand, provides strength, durability, and flexibility. By combining these two materials, stainless steel braided PTFE hose offers a range of benefits that make it suitable for various industrial applications.
How Does Stainless Steel Braided PTFE Hose Work?
Stainless steel braided PTFE hose works by using a PTFE inner tube that is surrounded by a braided stainless steel outer layer. The PTFE inner tube provides a non-stick surface that allows materials to flow through the hose with minimal friction. The stainless steel outer layer provides strength and flexibility, while also protecting the PTFE inner tube from damage. This combination of materials provides a hose that is both strong and flexible, with excellent chemical and temperature resistance.
