In chemical processing, the wrong industrial hose can lead to leaks, corrosion, or even equipment failure. That’s why chemical transfer hoses need to be chosen carefully, based on the type of media, temperature, pressure, and installation requirements. At IZOFLEX, we offer a range of chemical-resistant industrial hose types, including PTFE hoses, metal hoses, and composite variants, each with unique advantages depending on the job.

What is a chemical transfer hose?
A chemical transfer hose is an industrial hose designed to safely transport aggressive fluids – acids, solvents, alkalis, or other hazardous chemicals – without degrading. These hoses are used across industries like:
- chemical manufacturing,
- pharmaceuticals,
- water treatment,
- paint and coatings,
- hydrogen systems.
The hose you choose should be chemically compatible, pressure-resistant, and safe to operate under expected temperature ranges.
PTFE Hose: the go-to for aggressive media
PTFE hoses (made from polytetrafluoroethylene) are known for their high chemical resistance and thermal stability. They perform exceptionally well in environments where the fluid is corrosive or temperatures fluctuate.
Why choose PTFE hoses?
- Resistant to nearly all chemicals
- Handles both high and low temperatures (up to +260°C)
- Smooth, non-stick inner surface for easy cleaning
- Electrically insulating and non-reactive
- Low friction and low permeability
These properties make PTFE hoses ideal for chemical dosing systems, solvent transfer, and any application involving high-purity media, such as hydrogen fuel cell systems or pharmaceutical lines.
Metal hose: strength under pressure
When flexibility and mechanical durability are just as critical as chemical resistance, a metal hose is often the right choice.
Metal chemical hoses are made of stainless steel (typically AISI 316L) with a corrugated design for flexibility, and are often reinforced with wire braiding for high-pressure applications.
When to use metal hoses:
- High-pressure or high-temperature chemical transfer
- Steam or hot oil lines
- Environments with vibration or mechanical stress
Low permeation required (e.g. for hydrogen or gas transfer)
While they aren’t compatible with every chemical, metal hoses are extremely durable and long-lasting when paired with the right media.
Composite hose: lightweight and versatile for multi-chemical transfer
Composite hoses are multi-layered hoses made with thermoplastic liners, reinforcing fabrics, and metal wire helixes. They’re especially useful in bulk fluid handling, tank truck loading, and multi-chemical applications.
Why choose composite hoses?
- Lighter than metal hoses
- Good flexibility in long runs
- Broad chemical compatibility across fuels, acids, and solvents
- Anti-static versions available for explosive atmospheres
They’re often used in fuel depots, loading arms, and container transfer where a flexible but rugged industrial hose is needed.
