Definition of PTFE Hose

PTFE (polytetrafluoroethylene) hoses are a great alternative to rubber hoses. They feature excellent chemical resistance, a wide working temperature range (-70°C to +260°C), and self-cleaning properties that make them a great choice for nearly any application. With the right manufacturing and housing, PTFE hoses can be extremely durable and easily connect to any type of system. Each PTFE hose is highly resistant to most chemicals and does not release fumes, making them a great choice for enclosed spaces. PTFE hoses also have less surface friction than conventional rubber hoses, improving flow for any type of fluid and reducing wear over time. If your application requires a durable and non-reactive solution, PFTE hoses are the perfect choice.

Benefits of PTFE Hose

Tetrafluoroethylene is a fluoropolymer that goes by the name Polytetrafluoroethylene (PTFE). More places than simply chemical plants use PTFE hoses. In fact, their advantages are applicable in a variety of other industries. Despite having a high price tag, it offers several advantages that may be useful in diverse industries.

Non-Reactivity
The non-reactivity of PTFE is one of its most important benefits. PTFE can be used in chemical plants that produce chemicals containing acid, alkali, and other types of hazardous components. The potential of any contaminant mixing in the finished product is one of the main worries that food and pharmaceutical firms have when employing such equipment. However, this risk may be eliminated with the use of PTFE.

Temperature Endurance/ High Tolerance / Durability
Since a PTFE Hose can withstand temperatures as high as 250 degrees, it is the right choice for many industrial operations that entail heating components. In addition to being a superb electrical insulator, it can endure low pressure. Many industries can benefit from this robustness, especially those that work with heavy metals that are subject to a lot of wear and tear.

Flexibility
PTFE hoses are flexible, and you can boost the strength and flexibility of the hose assembly by including alternatives like convoluted bores, springs, and armor guards. You may have a reliable PTFE hose assembly that is flexible, incredibly strong, and works as light braided chemical hoses.

Reliability
A PTFE braided chemical hose is always the best option if you need something durable, whether for a lab, factory, or home. It can function at high pressure as well, unlike typical rubber hoses. With a steel coating all around it, the product is extremely dependable due to its low gas permeability and resistance to heat, electricity, kinks, and crushes. These in-house, CNC Swiss-made fittings made of 316L stainless steel are used to create these stainless braided Teflon hose assemblies. By purchasing these flexible and strong PTFE hoses, you may increase the performance of your industrial equipment.

What Is The Shelf Life Of PTFE Hose?

The PTFE hose assemblies are designed for reliable fuel, oil, and hydraulic fluid conveyance in even the most demanding aerospace systems.
PTFE hose assemblies are constructed with seamless, smooth-bore inner tubes for maximum flow and include a thin layer of carbon to eliminate static charge buildup. Braided with stainless steel for durability and wear resistance, PTFE materials are designed to withstand all aircraft fuel, oil, coolants, and solvents.
In addition, they feature an unlimited shelf life. Backed by years of aerospace engineering experience and design capabilities, PTFE hoses will provide the performance you need with the reliability you expect.

What Is the Temperature Rating of PTFE Hose?

Polytetrafluoroethylene (PTFE) is an engineered fluoropolymer. Outstanding resistance to chemicals is one of its primary attributes.
A broad temperature range of -54°C to 260°C makes this PTFE hose material suitable for the majority of fluids and ambient temperature conditions found in most industries. With all types of hose, increased working temperatures require a reduction in maximum rated working or burst pressure. Whenever excessive flexing, vibration, thermal fluctuations or rapid pressure impulsing is in evidence, further caution should be exercised in reducing the maximum working pressure.
An extremely low coefficient of friction (0.05 to 0.20) provides a non-stick surface. Water absorption of PTFE is negligible, less than 0.01% by ASTM test, and it is FDA-approved for food and pharmaceutical use.
PTFE will withstand flexing and vibration without failure from flex fatigue. PTFE is chemically inert. It will not break down or deteriorate in service, and it has an unlimited shelf life because properties do not change with age or exposure to weather. PTFE hose can be used in aerospace, automotive, chemical and industrial applications.

Which Is Better PTFE Or Rubber Hose?

PTFE (or polytetrafluoroethylene) hoses are an excellent alternative to rubber hoses. With the right manufacturing and housing, they can be extremely durable, and fitting them to a system can be quite simple. While they do not offer the same range of flexibility as rubber does, PTFE hoses are highly resistant to most chemicals and they do not often release fumes, which is important for any kind of enclosed space. This chemical resistance also means that PTFE hoses will break down a lot more slowly than rubber hoses will.

Polytetrafluoroethylene also has less surface friction than rubber, which means that flow can be improved by using PTFE hoses. While rubber is prone to break down at extreme temperatures, PTFE is highly temperature resistant, making it ideal for all kinds of industries.

Can PTFE Hose Be Clamped?

PTFE hose is too stiff for hose clamps. It won't "crush" onto a fitting to create a good seal, so unique aluminum AN fittings must be used to secure it.

PTFE is stiffer than rubber hose material, even though it has a much smaller outside diameter (about one-third the size, to be precise). That means the new hose can easily match the bend requirements of most applications.

Cutting PTFE hose is no different than cutting rubber hose, but AN fittings use a brass ferrule, or "olive," that crushes to provide the seal at the fitting/hose mating point. Because most PTFE AN fittings are a non-swivel type, it's difficult to create complete hose assemblies. Fortunately has a semi-swivel fitting that can be rotated on the hose to make it easier to build an assembly at home.

Although there are a few very-expensive, crimp-fitting PTFE AN hose/fitting products on the market, the only supplier we've found with aluminum fittings designed to work with the more common -6, -8, and -10-diameter hoses for do-it-yourself projects.

Also, one of the longstanding problems with PTFE fittings and hose has been non-swivel designs, which made "clocking" the fittings very difficult. Our project features a semi-swivel AN-fitting design that pretty much solves the problem, but some trial-and-error test-fitting is still required.

PTFE Hoses in Different Industries

Chemical Industry
The chemical processing and manufacturing industries utilise the use of PTFE hoses because of their ability to transport corrosive materials and chemicals. It can withstand harsh environments, which is necessary for chemical processing and manufacturing applications, by adding an added layer of protection.
