High Chemical Resistance
Teflon hoses are highly resistant to many compounds, including acids, alkalis, solvents and corrosives. This allows the use of PTFE hoses for conveying aggressive materials.
Heat Resistance
PTFE hoses can withstand extreme temperatures, both high and low. They have excellent thermal stability, which allows them to maintain their physical properties and performance even in harsh environments.
Non-adhesion
PTFE is a non-stick material, which means it has a very low coefficient of friction. This property makes Teflon hoses ideal for applications where sticky materials are transported, such as in the food processing industry. Another advantage of non-stick is that the hose is easy to clean.
Flexibility
PTFE hoses provide excellent flexibility and are easily bent, making them easy to fit and place in complex configurations. This flexibility allows for easier installation, reduces the need for additional adapters, and allows them to be used in tight spaces or hard-to-reach applications.
Electrical Insulation
It is also an important aspect that PTFE is an electrical insulating material, which contributes to the fact that Teflon hoses can be used in areas where electrical insulation is required. It is often used in the electronics and electrical industries, especially for the transfer of high purity chemicals and gases.
Low Friction
PTFE hoses have a smooth inner surface, thereby resulting in minimal friction during fluid flow. This feature enables efficient and undisturbed flow, reducing pressure drop and optimizing system performance.
Long Life And Durability
Hoses of this type have a long service life due to their resistance to chemical degradation, high temperature stability and excellent mechanical properties. They withstand repeated use, harsh conditions and exposure to various elements without significant wear or deterioration.
Composition and Structure
PTFE hose is composed of a smooth bore inner core made of PTFE material. This core is typically reinforced with braided stainless steel wire or other suitable materials to enhance the hose's strength and pressure resistance.
The outer cover can be made of stainless steel, polypropylene, or other protective materials depending on the specific application requirements.
The structure of a PTFE hose consists of several key components that work together to provide its unique properties.
Inner Core: The inner core of the PTFE hose is made of Polytetrafluoroethylene (PTFE) material. PTFE is a fluoropolymer known for its exceptional chemical resistance and low friction characteristics. The inner core is smooth and provides a non-stick surface for fluid transfer.
Reinforcement: To enhance the strength and pressure resistance of the hose, it is reinforced with braided stainless steel wire or other suitable materials. The reinforcement layer adds structural integrity and prevents the hose from collapsing or bursting under high-pressure conditions.
Outer Cover: The outer cover of the PTFE hose is designed to protect the inner core and reinforcement. It can be made of stainless steel, polypropylene, or other protective materials depending on the specific application requirements. The outer cover also provides additional resistance against abrasion, chemicals, and external factors.
What are Features of PTFE HOSES
Excellent Chemical Resistance
PTFE is renowned as the most chemically resistant material known. Only a very few, very unusual substances and conditions can affect it, like Fluorine gas at high temperature and pressure and liquid, boiling sodium metal.
PTFE lined hoses can therefore be used for a wider variety of chemicals than any other hose type, making it the ideal choice for very corrosive chemical applications and multiproduct applications.
Non-Stick Surface
The use of PTFE as a surface for cookware products has demonstrated to the world how easily cleanable PTFE surfaces are.
This means that PTFE lined hoses can be purged 100% clean more easily, faster and more reliably than any other type of hose.
Excellent Temperature Range
Temperatures from -70ºC up to +260ºC, dependent upon the hose design and the application conditions.
Hose Maintenance Tips
Prevent premature washdown hose wear and failure. Washdown hoses are often subjected to physical abuse while in service. Select a hose that meets or exceeds the application it is intended for.
Consider temperature, pressure, and environmental concerns such as abrasion and chemical resistance. Every plant should have a maintenance and inspection plan in place to ensure the longest possible life of the hose.
Be sure to consider these steps in your plan:
Store hoses properly when not in use. Hose racks or reels are highly recommended to keep hoses off the floor and out of harm's way. Pay attention to humidity, temperature, ozone, and sunlight. Storing them out of direct sunlight, in a room with moderate humidity and a temperature range of 50° to 75°F, is recommended.
Always shut off the water supply to the hose when not in use, and open the nozzle to relieve the pressure before storing. Leaving water in the hose subjects it to constant pressure and will shorten its life.
Don't pull the hose by the nozzle; this puts undue stress on the connection point.
Avoid exceeding the hose's rated bend radius. Kinking the hose can create weak spots in the hose wall. Consider using hoses with internal springs or kink guards to prevent kinking directly behind the coupler.
Never exceed the rated temperature and working pressure of a hose assembly.
Routinely inspect hoses for wear and damage. Look for external damage such as stiffness, discoloration, cuts, cracks, kinks, blisters, excessive abrasion, and exposed or broken wires.
Regularly inspect fittings. A hose should be removed from service if any fitting movement or damage is found that could prevent it from operating as intended.

Things to Consider When Choosing a PTFE Hose for Your Application
At first glance, hoses may seem simple and are often overlooked, not regarded as focal points amid other engineered components in an application. This neglect may contribute to hoses being subjected to abuse and mistreatment in the field. However, hoses represent a complex network of elements that work together to perform tasks typically handled by piping or tubing. Their essential function as a "flexible connection" on a P&ID is easily taken for granted. To select the proper hose for an application, one must consider material compatibility, hose strength, flexibility, insulation, and permeation, among other factors. Misunderstanding any of these aspects during specification can dramatically impact the hose's service life, leading to increased maintenance and heightened safety risks.
Materials
Most hoses fall into one of five families: Metal, Hybrid, Fluoropolymer, Thermoplastic, and Rubber. Each type has its limitations, so where should you start? A quick way to narrow down the options for a specific application is to compare the design pressure and temperature against different hose types.
Metal Hose: Made from a thin corrugated tube, metal hoses offer flexibility and higher pressure ratings but can suffer early fatigue in dynamic applications where constant movement occurs. Consequently, metal hoses are typically used in static, high-pressure/temperature applications where permeation must be minimized.
Fluoropolymer Hoses (PTFE): Often employed in applications where chemical compatibility is crucial, PTFE hoses have smooth cores and are highly flexible. However, they can experience permeation in gas applications, especially with small molecules like hydrogen and helium. Gas molecules can migrate into the lattice structure of the fluoropolymer and eventually leak out.
Rubber and Thermoplastic Hoses: These hoses also feature smooth cores and are often chosen for specific applications, such as hydraulic systems (thermoplastic) or lower-criticality applications (rubber). Each core material has its strengths and weaknesses regarding permeation resistance.
Static Dissipation
A critical aspect often overlooked in hose selection is how the hose manages static dissipation. As gases or liquids flow through the hose, friction can cause a build-up of electrons on the inner core wall. In non-conductive materials (PTFE, Rubber, Thermoplastic), this charge accumulates until it jumps from the inner wall to the outer metal braid, creating a pinhole in the core tube and resulting in small leaks. When specifying a hose for applications where static dissipation is a concern, consider a metal core or a PTFE hose with a carbon-infused core. This infused core allows the static charge to travel slowly and in a controlled manner, preventing potentially damaging discharges.
Flexibility
Since hoses are often used in dynamic applications, flexibility is a critical characteristic to consider. Most hose vendors provide the minimum centerline bend radius, which is the point at which excessive bending can significantly reduce the hose's expected lifespan. Additionally, manufacturers typically publish a recommended minimum straight length before any bends occur after the end connection. This precaution prevents bending or kinking at the collar, extending the overall service life.
Insulation
Due to their typical placement in the field, hoses can pose significant safety risks for burns in hot services. Like other pipes or tubes, hoses can be insulated. Insulation protects operators from burns and can also insulate the process, resulting in lower heat losses.
Insulation offers some protection for the outer hose braid as well. A thermosleeve or spiral guard can shield the hose from abrasion as it moves and comes into contact with other surfaces where insulation may not be necessary. Additionally, an armor guard can further protect the hose from damage.
