The flexible stainless steel hose manufactured at Proflex Hose is suitable for use with both liquids and gases in a variety of intensive applications. As a stainless steel conduit, it is highly resistant to heat and can be used in high-temperature roles, while also being very resistant to corrosion. This corrosion resistance gives flexible stainless steel pipe the ability to survive in tough environments and carry a range of fluids. A tough, resilient and long-lasting material, stainless steel flexible conduit is perfect for use in a wide range of applications.

Stainless Steel Hose Construction
The flexible metal hose available from Proflex Hose is made to a strict standard, ensuring a reliable, high-quality hose that always performs to the level you require. The core of the flexible stainless steel hose is a relatively thin tube, which is corrugated to allow flexibility in any direction without compromising strength or durability. Around this flexible core, a weave of stainless steel wire is placed, sheathing the interior tube and providing impressive resistance against pressure from inside and out, as well as improving durability and providing powerful protection against physical damage, corrosion and the elements. More than one layer of this braiding may be fitted as necessary, depending on your needs.
Flexible Stainless Steel Conduit Applications
As the corrugated interior tube is seamless, stainless steel conduit is ideal for use with liquids or gasses under pressure, especially when fitted with external braiding. With first-rate corrosion resistance, a stainless steel flexible conduit is also ideal for use in chemically demanding situations – and this combination of factors makes them absolutely perfect for use in the petrochemical industry, or in steelmaking, chemical smelting, the automotive industry the power generation industry and dozens more.
These stainless steel hoses can be used in a range of roles within these industries, including carrying fluids and gases, correcting misalignment in piping or absorbing vibrations.
When you purchase a flexible metal hose from Proflex Hose, you can be sure that you are receiving a quality product. All of our stainless steel conduits are tested underwater, pumped full of compressed air and held under high pressure to ensure no leaks anywhere on the assembly.
Use in Application
The limitations of Proflex Hose’s flexible stainless steel hose are specified in the product manual, but other factors may influence the capabilities of your product, including mechanical abuse, abrasions or exceptional usage demands. Unless all of these details are provided to Proflex Hose in advance to allow the recommendation of the best possible product for your needs, then Proflex Hose regrets that it cannot accept responsibility for unsatisfactory performance.

PTFE convoluted hose is a hard-wearing multipurpose hose which is suitable for a variety of applications. Made from convoluted PTFE for seamless construction, PTFE hose pipe has excellent flexibility and sports impressive resistance to temperature and chemicals, and is easy to clean and maintain.
These attributes make convoluted PTFE hose an excellent choice for a wide range of applications, including steam transfer, refrigeration, the automotive industry, and more!
There are three varieties of PTFE convoluted hose available from Proflex Hose. Each of them is based on a base layer of PTFE convoluted tubing, providing a seamless pipe, able to resist temperature and chemical corrosion and providing an easy-clean PTFE pipe solution which suits dozens of industries.
The first available variety of PTFE convoluted hose available from Proflex Hose is “tube only”, which is an unsheathed PTFE hose. Extremely lightweight, you also benefit from the semi-transparency of the material, but operating pressure must be drastically reduced to no more than 2 Bar.
If you want to compromise between lightweight PTFE convoluted tubing and pressure-capable hose, you can choose the flexible PTFE tubing with polymer braid, which coats your PTFE hose with a sheath of braided orange polypropylene monofilaments, resulting in a hose with excellent chemical resistance at low weight and a much-improved pressure tolerance.
For maximum pressure resistance, chemical resistance and physical durability, choose the stainless steel braided PTFE flexible tubing from Proflex Hose. Coated with a sheath of braided stainless steel wires, this PTFE convoluted tubing is able to work at double the maximum pressure of Polymer Braided hose, and considerably higher temperatures. The stainless steel wire braid also provides considerable physical armour against knocks, abrasions or other mechanical damage.
All three grades of PTFE hose pipe are available with an anti-static PTFE tube instead of the conventional semi-transparent PTFE liner. This anti-static liner is necessary when fluids exhibiting high electrical resistance, like solvents or fuels, are piped through the convoluted PTFE tube. With a lower electrical resistance between the liner and the end fittings, any static electricity which is beginning to collect on or within the pipe can dissipate harmlessly before building to potentially risky levels. This is in accordance with BS2050:1978 – but if in doubt, contact Proflex Hose to see whether your application will need anti-static hose.
PTFE hose pipe can be used in a huge range of applications, including the petrochemical industry, automotive industry, or in refrigeration or steam transfer, thanks to its chemical and thermal resistance.

Convoluted PTFE hose can be supplied without the end fittings already attached, to be assembled on-site or by distributors with either hydraulic end fittings or the short-tail fittings often seen with PTFE hose. PTFE convoluted hose is easily made to fit the spigot tail diameter by using a supplied tool, opening up the convolution to allow the insertion of the spigot without applying heat. Alternatively, you may choose a complete pipe assembly from Proflex Hose, which are available with all conventional types of PTFE hose end fitting. If you would prefer, hoses can also be supplied with ends “cuffed” to enable you to fit your own end pieces.
If necessary, both the PTFE convoluted hoses and the full PTFE hose assemblies can be provided with full certificates of conformity, alongside certificates confirming successful tests and materials quality. However, if you need these items to be included with your order, please be sure to specify this while placing the order with us.
Use in Application
Usage limitations of PTFE convoluted tubing are specified herein, but over the course of a particular application, other limiting factors such as physical abuse, mechanical damage, safety risks to your workforce and other risk factors may impact performance. Unless these details are provided to Proflex Hose Limited in advance to allow the most suitable product to be recommended, we regret that we cannot accept any responsibility for unsatisfactory performance.
