Shape Of PTFE Tubes
According to different applications, we have several different shape of PTFE tubes:
Smooth Bore PTFE Tube
PTFE smooth bore tubing is a smooth bore shape tube extruded by high temperature sintering. It is suitable for applications where bending radius requirements are not critical.
This straight tube is the most basic design, and its smooth surface has a very low coefficient of friction, providing a higher flow rate and flushing, thus reducing process contamination residues. PTFE tube is high temperature resistant and high pressure, can operate in high temperature environment. In addition, the material has flexibility, chemical resistance, non-flammability and heat resistance. It also has a high dielectric strength and is inert to most chemicals and solvents.
PTFE Corrugated Tube
PTFE corrugated tube has excellent flexibility and kink resistance for applications where require a tighter bending radius, increased pressure handing or anti-extrusion capability. Convoluted tubing can be sourced with flares, flanges, cuffs, or a combination of multiple optimized tube solution. All the tubes are available in anti-static(carbon)version.
PTFE Convoluted Smooth Bore Hose
PTFE convoluted smooth bore hose is different from any other PTFE hose product currently available, Its lined tube interior is smooth, but 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's design to give the customer the best choice for both.
PTFE Capillary Tube
PTFE AWG (American gauge) tubes provide the ultimate service for lubrication, high-temperature resistance (welding resistance), chemical resistance, biocompatibility, wear resistance, and precision extrusion tolerances. It is a flexible and translucent, small-size PTFE tube, These small-size flexible PTFE capillaries are usually sold at 100 m, 153m, 250m, and 305m per roll. The wall thickness is less than 0.5 mm, and the outer diameter is less than 10 mm, which is widely used in medical treatment, electrical insulation, and other applications.

FEP Tube
FEP tube (vinyl fluoride) is an extremely transparent fluoride plastic tube that is more transparent than PTFE, making it ideal for visual lens / flow monitoring applications. Is an economical option for applications requiring chemical resistance and extensive contact temperatures.
The FEP tube has a slightly higher low coefficient of friction, low temperature for continuous use and, although up to 200 degrees, has chemical and dielectric properties similar to those of FEP. In addition, the FEP oil tube also has better gas and vapor penetration performance and excellent UV transmission rating.
PFA Tubing
PFA (perfluoroalkoxy) tube is a fluoropolymer tube, and its discovery combines the advantages of PTFE and FEP. The modifier used in PFA resin has the same maximum use temperature and chemical inert as PTF, so its performance and use temperature and PTFE material are basically the same.
In addition, the PFA has a higher working pressure. But unlike FEP, the chemistry of PFA makes it very low volatile, thus in wide and diverse applications in many industries such as pharmaceutical, laboratory sampling and semiconductors.

Applications For PTFE Tube
PTFE tube is an essential part of any 3D printer, either as a filament conduit on a direct drive system or as a Bowden setup for the filament path itself. Low friction and tight tolerances are very important for consistent and reliable performance, providing great printing and easy filament loading. We have PTFE tubing made for that.
Suitable sizes for 3D printer: 2x4mm, 4x6mm
Available colors: white, blue, red, green, black, and etc.
PTFE tube is also often found on coffee machines, it would normally be used to carry water under pressure and would use suitable connectors at each end, like brass bushing. Length is very important when used in coffee machine. If it is shorter or longer, it will mess with the HX intermix and change the recovery rate and stability of the heat exchange system.
Suitable sizes for coffee machine: 1/8’’x1/4’’, 2.5x4mm, 3x5mm, 4x6mm, 6x8mm and etc.
PTFE corrugated tube has high-temperature resistance, corrosion resistance, aging resistance, and good flexibility, which makes it great choice as liquid cooling lines for many electronic components, mostly found in data centre, industrial computers.
FEP maintains its strength and benefits in a wide range of temperatures and conditions. FEP tubing is designed with enhanced chemical resistance with advanced gas and vapor permeability properties and excellent UV transmission ratings. FEP tubing also provides increased clarity over PTFE with a higher coefficient of friction, crystallinity, transparency and lack of microporosity, which made it ideal choice for pneumatic industry to transfer gases without leakage.
In the pharmaceutical industry, companies must rely on plumbing to maintain the purity of the material. For example, ultra-pure water transported through resin tubes must be able to maintain chemical purity throughout the process; PFA's inertness to chemicals, including other hazardous contaminants that can be found in laboratories, such as sulfuric acid, makes it a high-quality standard unparalleled choice. For pharmaceutical companies that require frequent use of highly corrosive materials such as nitric or phosphoric acid, PFA tubing will easily withstand its otherwise destructive properties.
Fittings For PTFE Tube
Advantages: Quick manual connection and disconnection, no tools required, no flow loss, flow depends on the inner diameter of the tube.
Disadvantages: low pressure, working pressure 0-10 bar.
Advantages: Quick connect and disconnect, requires tool switch. Simple structure, no seal, easy connection. The pressure and temperature depend on the properties of the tube.
Disadvantage: Only suitable for soft tubes such as Nylon, PU or PTFE.
The compression fitting is composed of valve body, nut, front ferrule and rear ferrule.
Advantages: High pressure, no seal.
Disadvantages: Only suitable for rigid pipes, such as copper pipes, stainless steel pipes, aluminum pipes, etc. When using PTFE tubing or nylon tubing, the inner copper tubing must be used.
PTFE Tube : The Ultimate Guide
PTFE tubing is a corrosion-resistant tube that is used in many industrial applications. PTFE tubing is one of the only materials that will withstand certain types of acid. The tubing can be adapted to work in many situations. PTFE tubing is very low friction and can help to improve flow. Sometimes PTFE tubing is used in food service applications as well.
What is PTFE?
PTFE is the abbreviation for polytetrafluoroethylene, a synthetic polymer that consists of 2 basic elements namely carbon and fluorine.
Properties of PTFE Tube
High chemical resistance
Distinctly inert
Withstands temperatures of up to 240°C
Superior dielectric strength
Benefits of PTFE Tube
Suitable for carrying highly corrosive/reactive fluids
Extensively useful in medical applications
Effective in high-heat applications
Insulating medium in cables and heavy electricals
Ptfe Bowden Tube Max Temp
Our Teflon connector tubing can withstand temperatures from as low as -180C to as high as 260C, making it ideal as spare parts for 3D printers.
Ptfe Tube Max Temp
PTFE tubing is chemically resistant, has a low coefficient of friction, and broad temperature range from 500°F (260°C) to -454°F (–270°C).
Ptfe Tube Melting Temp
Due to its high flexibility, PTFE is mostly used with microfluidic fittings in low-pressure applications. Its melting point is reached at 327°C, making it a material of choice in high temperature applications.
Ptfe/fep Tube Shrink Temperature
about 330 °C
During the shrinking process, the outer PTFE layer shrinks at a temperature of about 330 °C
How To Remove Ptfe Tube From Extruder
To remove the PTFE tube from your extruder, you should depress the circular plastic coupler to release the teeth that hold the tube in place, then pull out the PTFE tube. If you can't pull it out, unscrew the whole fitting from the extruder, then apply more pressure to the coupler using tools and remove the tube.
How Long Ptfe Tube Throat
5mm from the end. this will seal your connection between you nozzle and throat.
What Is Ptfe Tube For 3d Printer?
PTFE is a very common component used in filament-based 3D printers. It's the white material used in tubes guiding filament towards the extruder and hot end. Bowden-style 3D printers require the use of PTFE tubes to ensure the extruder can push the filament properly, but direct extruders do not require such tubes.
How To Clean Out A Clogged Ptfe Tube For 3d Printer?
Sometimes, the filament can get really stuck in the PTFE tube and can not be removed by hand. In that case, boiling the tube in water can help. This softens the filament inside and afterwards you can push it out. The PTFE does not get harmed by the boiling water, as it is resistant to much higher temperatures.
When To Replace Ptfe Tube?
I believe the recommended time for nozzle change is about an half a year. But depends on what filament and how often you print.
