PTFE HOSE ASSEMBLIES
Stainless Steel Braided PTFE Hose & Rubber Covered PTFE
PTFE Hose is a very versatile and durable alternative to rubber hose. PTFE (Polytetrafluoroethylene) is used as a liner for stainless steel braided hose or rubber hose to increase temperature range compatibility, chemical resistance, flexibility and shock resistance. Specific characteristics & high chemical/temperature tolerances make this a popular choice among engineers and facilities managers. At McGill Hose & Coupling, we will closely partner with you and your team to fabricate the best solution for your specific application needs. Choosing the correct PTFE hose fabricator is paramount to achieving the best possible hose assembly for your most critical fluid transfer applications.
Key Industries Served:
Pharmaceutical, Automotive, Power Generation, Cosmetics, Chemical Transfer, Food & Beverage.

PTFE Hose for Food & Beverage Industries
Dissolved oxygen (DO) is a major issue for the food and beverage industries due to the repetitive up-and-down action of food and beverage processing equipment. PTFE and PTFE-lined hose construction is ideal for food and beverage efficient product transfer and handling while simultaneously offering an exceptionally long service life. Its design retains a smooth circular bore without distortion, resulting in smooth, consistent flow with minimal turbulence.

PFTE HOSE PRODUCTS
MEDIUM PRESSURE SMOOTH BORE
Medium pressure smooth bore Fluoropolymer (PTFE) hose ( PSI) features an inner core of PTFE hose reinforced by an outer layer of stainless steel wire braid for strength and protection. This flexible water hose is widely used for a wide spectrum of applications including demanding compressed gas and industrial applications. The low-friction surface of smooth bore hose provides for high flow rates and these hoses are easily drained and/or cleaned. Our custom, precisely machined fittings will result in a truly reliable hose assembly for all of your demanding applications.
Rubber Covered – Chemical Hose
Chemical transfer hoses are typically
rubber covered polytetrafluoroethylene or PTFE hoses. Chemical hoses (also referred to as chemical transfer hoses) are used to move chemicals from one location to another. These hoses are manufactured from materials that are highly chemical resistant. Rubber covered polytetrafluoroethylene or PTFE hoses are used in applications such as transferring acids, solvents, and petroleum products to or from storage containers in industrial plants and are also used for spraying pesticides, fertilizers, and paint. Bulk chemical hoses can be cut to the desired length and compatible chemical resistant hose fittings(Coupling alloy and gasket must be compatible with chemical being transferred) can be added to the ends of the hoses to create custom hose assemblies. Chemical hoses are FDA approved per 21CFR177., US Phamacopeia Class VI, 3-A Sanitary Standard 62-01.

ANTI-STATIC/CONDUCTIVE HOSE
A safe solution where static can build up in especially high flow rate applications. Static can be very dangerous in hose applications by jumping through the tube to the braid and cause failure if a conductive hose is not used. When using flammable media, if a standard, non-conductive hose is used static could ignite the media. By using a conductive hose, it will facilitate transfer of the static charge to the end fittings and ground.
CONVOLUTED
Convoluted PTFE hoses are manufactured with smooth, rounded, helical shaped convolutions which help to promote easy cleaning and self-draining for the ultimate high purity, convoluted hose. Key features of convoluted hoses are that they are lightweight and their flexibility provides a superior flex life.
High Pressure / HI-PSI PTFE HOSE
Hi-PSI hose is needed in applications where high and low temperature, chemical resistance, low coefficient of friction, flexibility, and non-aging characteristics are required. Hi-PSI Series hose is a heavy wall hose for very high pressure applications and the reinforcement is braided and not spiraled allowing for better hose flexibility.
Process Hose
PTFE (Polytetrafluoroethylene) has exceptional chemical resistance, can be used at temperatures up to 260°C (500°F), and it’s unique non-stick properties make surfaces self cleaning. These advantages make PTFE the best possible lining material for flexible hoses in a wide range of fluid flow applications, in particular for pharmaceutical and chemical fluids transfer, and in many automotive and aerospace applications.
In many instances, performance requirements for PTFE Process Hose include excellent chemical resistance, a smooth bore to ensure clean, fast fluid flow, resistance to high pressures and full vacuum, and excellent flexibility and kink resistance.
Flouropolymer Tubing
Fluoropolymer material is recognized for heat tolerance — up to 500°F continuously. It also excels at performing in extremely cold temperatures. With few exceptions, fluoropolymer tubing can handle virtually any corrosive chemical in use today – including solvents, acids, and bases.

Hi Peter,
Zero response's, so thought I would do some speculating:
Know nothing about PTFE fuel hose/lines.
Weight saving? - What do you estimate (grams) compared with the same installation in rubber?
What will the service life of the PTFE be? Will you still replace at the recommended 5 year rubber replacement?
How does PTFE compare with rubber for abrasion resistance ? movement/vibration tolerance? heat tolerance?
If push fit, unlikly to have any advantage over correctly sized (ID) quality, rubber ones.
Does PTFE require special clamps/connectors (cost? weight? complexity?)
Sounds comparatively (to rubber) expensive. If extended life (longer than 5 years) cost per annum may, or not, be less.
PTFE may be used, as a liner, in some rubber fuel hose (FI hose?)
This video has some thought provoking information:

Hi Sean,
thank you for looking at this post from various perspectives, and for the link to the vid.
I am looking at a non braided type (no metal mesh) and expect approx. 40% weight reduction. Yes, PTFE (Teflon) is pretty dear. However, once it’s done it’s done. They should last a lifetime long. PTFE is very resistant to heat. Ratings go up to 260C.
For more information, please visit Flanged Flexible Metal Hose.
As per now I was not able to verify if those hoses actually work as push on. With special connectors and fittings the cost side would suffer even more and so would the weight saving.
My research led me to a lad who replaced 8m of rubber fuel hoses in his plane by PA12 hoses. They are very light, too, and far less expensive. For temp rating reasons he stuck to rubber underneath the cowling. I found PA hoses with a temp rating of 130C (some are rated only 80C, some 100C). In my opinion the 130C type should work underneath the cowling, too. With fire sleeves that should be OK anyway.
Regards
Peter
Hi Peter,
I would speculate that PTFE would need to be very carefully supported against vibration/movement and bends quite large radius to prevent kinking.
I am no fan of aluminium fuel lines but at least the equipment is available to make quite tight radius bends.
My preferred system is a combination of "rubber" & aluminium as the installation situation dictates. Aluminium is great for long runs in wings/fuselage. Rubber for short multi bend runs & connecting to fittings such as in line filters, pumps, etc., especially where vibration/movement may need to be accomodated.
I also like the push fit of rubber - done well its absolutely leak free/light weight/ low cost & soooo simple
