China Suppliers Factory PTFE/Teflon Lined Wire Braided Metal Hose for Enhanced Corrosion Resistance
PTFE/teflon lined wire braided metal hose is braided Convoluted hose comprised a convoluted PTFE tube liner and single or double stainless steel outer braid. It’s lightweight, has excellent flexibility, kink resistance and corrosion resistance for superior performance in chemical transfer, high temperature hydraulics, can be design and used in automotive, fluid handling, chemical transfer, paint, pharmaceutical, food & beverage processing, cosmetics and general-purpose applications.
Advantages
-
Meanwhile, It can be used for a long time at -60～250℃, has reliable and excellent corrosion resistance, and is used to transport strong corrosive media under high temperature. Its service life of PTFE corrugated metal hose is much longer than the existing steam hoses. It does not need to be replaced after long-term use, which greatly reduces the use cost, improves the use efficiency, economical and practical.
-
PTFE lined metal hose core is made from virgin 100% PTFE resin without any pigment or additive, PTFE is a good anti-friction and self-lubricating material with low friction coefficient, and its static friction coefficient is less than its dynamic friction coefficient, so it has the advantages of low starting resistance and smooth running. Meanwhile, it is an excellent electrical insulation material.
-
Wire braiding is produced from AISI 304 or 316 stainless steel wire, also can be customized.

Q
What materials are used in the core and outer braiding?
The hose core is made from 100% virgin PTFE resin without any pigments or additives. The outer wire braiding is produced using premium AISI 304 or 316 stainless steel, which can also be customized.
Q
What are the primary applications for this PTFE metal hose?
It is designed for demanding environments, including automotive, fluid handling, chemical transfer, paint systems, pharmaceutical manufacturing, food & beverage processing, cosmetics, and general-purpose industrial applications.
Q
How does the service life of this hose compare to standard steam hoses?
The service life of the PTFE corrugated metal hose is significantly longer than existing steam hoses. It does not require frequent replacement, which greatly reduces operational costs and improves overall efficiency.
Q
Does the PTFE liner offer good flow efficiency?
Yes, PTFE is an excellent anti-friction and self-lubricating material. It has a low friction coefficient, meaning its static friction coefficient is less than its dynamic friction coefficient, ensuring low starting resistance and smooth fluid flow.
