Our Products

Smooth Bore PTFE Hose

PTFE smooth bore hose is made from 100% PTFE inner tube and braid with SS wire. This is a basic PTFE hose design that has been used successfully in many automotive and general-purpose applications. It is ideal for high temperature or corrosive media such as food, beverages, adhesives, paints, pneumatic systems, automotive and hydraulics.

Available sizes range from 1/8’’ to 1’’.

Convoluted PTFE Hose

Convoluted PTFE hose is made by vacuum forming process. The main feature of the hose is that it has greater flexibility and bendability. and its small bending radius increases with the increase of the hose’s diameter. It is different from the smooth hose in addition to a certain strength and stiffness, but also has large flexibility and high fatigue resistance, which make convoluted hose has a very wide range of applications.

 

Available sizes range is from 1/4’’ to 2’’.

 

Convoluted Smooth Bore Hose

Smooth Bore Convoluted Hose is different from any other PTFE hose product currently available, Its lined tube interior is smooth, but it is corrugated on the outside. Therefore, it can meet the problem of high mobility but not obstruction, and can also solve the strict requirement of bending radius. It designed is to give the customer the best choice for both.

 

Available sizes range is from 3/8’’ to 1’’.

Uses For PTFE Hose

PTFE smooth bore hose APPLICATIONS
Hot Runner System

PTFE smooth bore hose is normally used for general purpose application like hydraulics, as well as the specific applications which require for high temperature resistance, and high pressure resistance, like Aerospace industry and hot runner system(water hose, air hose, oil hose);

PTFE smooth bore hose APPLICATIONS 1
Automotive Lines

For AN series PTFE smooth liner hose, it can be used for automotive as brake & clutch lines, transmission cooler lines, gauge lines, power steering lines, turbocharger oil lines, fuel oil lines and etc;

 

PTFE smooth bore hose APPLICATIONS 2
Adhesive Dispensing Machines

Due to the PTFE's non-viscosity, PTFE smooth bore hose also can be used in adhesive dispensing machines, hot melt adhesive dispensers;

PTFE smooth bore hose APPLICATIONS 3
Air Humidification System

PTFE's aging resistance makes it the best choice for long-term use or outdoor all-whether use to maintain its stability, such as air humidification system and etc.

PTFE convoluted hose APPLICATIONS
Air Compressor

PTFE convoluted hose has excellent flexibility and kink resistance, which can be widely used in industries with high requirements for bending and frequent movement, like air compressor for bus, and HVAC system;

PTFE smooth bore inner & corrugated outer hose APPLICATIONS
Biopharmaceutical Industry

Combined the advantages of PTFE smooth bore hose (high flow rate, excellent cleanability and high pressure, easy to clean & crimp) and convoluted hose (outstanding flexibility and sufficiently bent), PTFE smooth bore inner and convoluted outer hose becomes a great ideal option for the applications with higher requirements, such as biopharmaceutical industry.

Comparison Of PTFE Hose And Other Hose

PTFE smooth bore hose VS rubber hose
PTFE Smooth Bore Hose VS Rubber Hose

1、PTFE hose has minimal volumetric expansion (hose swelling), it is much better than the rubber hose as hydraulic brake lines for powerful braking and amazing feel.

2、Rubber can penetrate some chemicals and release smoke. It has a high surface resistance and can reduce flow. It can be heavy. The decomposition rate of rubber is also much faster than that of PTFE. PTFE hoses are highly resistant to most chemicals, and they do not often release smoke, which is important for any kind of enclosed space. This chemical resistance also means that the decomposition rate of PTFE hoses is much slower than that of rubber hoses.

3、The surface friction of PTFE is also less than that of rubber, which means that the flow can be improved by using a PTFE hose. Rubber is easy to decompose at extreme temperatures, and PTFE is resistant to high temperatures, making it an ideal material for various industries.

PTFE convoluted hose VS stainless steel convoluted hose
PTFE Convoluted Hose VS Stainless Steel Convoluted Hose

1、Although the long-term operating temperature of regular stainless steel 304 convoluted hoses can reach 800℃, and the working temperature of PTFE can only reach around 260℃, the corrosion resistance of PTFE is much better than that of stainless steel, and PTFE is almost inert to all chemicals.

2、PTFE is more resistant to aging than stainless steel, so PTFE is less prone to aging and more durable during use. Therefore, PTFE convoluted hose becomes a better choice in applications where the temperature is within 260℃ instead of stainless steel convoluted hoses.

3、Under the same stainless steel wire braiding conditions, the pressure resistance of the PTFE convoluted hose will be relatively higher than stainless steel convoluted hoses.

Review Of PTFE Hose Assemblies

PTFE smooth bore hose with crimped ends

PTFE Smooth Bore Hose With Crimped Ends

Crimping PTFE hoses and fittings can be done by our factory facility. After the PTFE hoses pass a series of tests such as airtightness test, pressure test, leakage test, etc., the crimping parameters are set according to the specifications of the hose, and then the first sample is made and tested. Before shipment, we will batch test all the crimped assembled hoses.

PTFE convoluted hose with crimped ends

PTFE Convoluted Hose With Crimped Ends

In order to better crimp, we will use a specially customized ferrules for crimping. This kind of ferrule is thick in the middle and thin on both sides, which can be completely crimped without leakage under correct crimping conditions; for better sealing, we can also make cuffed ends, flared ends at both ends, and then crimp the flanged ends.

AN Series PTFE Lines With Crimped Ends

To crimp PTFE lines with AN fittings in crimp type, it can be also done at our facilities, it requires a hydraulic press with specific dies to properly crimp the collar onto the hose ends. The Crimp style hose requires a new crimp collar to be reused but is considered to be the strongest most reliable fitting if crimped correctly.

AN series PTFE lines with assembled ends

AN Series PTFE Lines With Assembled Ends

This kind of hose assemblies is made by reusable hose ends, can be assembled and serviced using hand tools. The reusable hose ends use a two part system to hold the hose in place. They come in a variety of different sizes, angles and colors. They are slightly heavier but are claimed to have a more secure hose clamping method than push locks.
