What is a PTFE Convoluted Tube？

PTFE is more heat resistant than FEP, enabling it to be used continuously at higher operating temperatures. Additionally, it has a lower coefficient of friction than most other plastics, allowing for easier cleaning as is the case with FEP. PTFE convoluted tubes offer significant flexibility as well, though unlike FEP tubing they allow for self-draining due to the structural properties of the convolutions. Due to its chemical resistance, PTFE tubing is also used to carry both industrial and natural solvents.

Benefits of PTFE convoluted tubes include: 
1.Approved by FDA for food and pharmaceutical processing.
2.Chemically inert when exposed to most chemicals.
3.Easy to clean.
4.Functions well in wide temperature ranges, from –85-500°F (–65-260°C)
5.Dielectric properties make it a good insulator. 
6.Longer lifecycle due to UV resistance.

With the addition of cuffs, PTFE convoluted tubing can easily attach to barbed or compression fittings. 

Applications for PTFE Convoluted Tubes

Since PTFE convoluted tubes offer resistance to temperature extremes and chemicals, they are useful in an array of industries. As per tubing made with FEP, when PTFE tubing is braided with stainless steel it suits high-pressure applications well. Manufacturers in the automotive, chemical, food, medical, petrochemical, pharmaceutical, semiconductor and other sectors all utilize this type of tubing.

Applications for PTFE convoluted tubes include:

1.Charging various industrial cylinders with gas, including acetylene, argon, helium, oxygen and nitrogen.
2.Coolant lines for electronic equipment. 
3.Coolant, brake fluid, fuel, oil and other fluid-carrying hoses in vehicles.
4.Cooling and heating lines for injection molding equipment. 
5.Cooling hoses that do not conduct electricity on radio and television transmitters. 
6.Cylinders that provide pressurized air or oxygen in breathing apparatus.
7.Dehydration lines for steam purging of refrigerant gas in air-conditioners.
8.Electrical cabling in the aerospace industry
9.Electrical power conduits for hot bottle stacking machines. 
10.Feeder lines to burners in power plants. 
11.Filling barrels of spirits in the distilling industry. 
12.Gas lines for paintball guns.
13.Heat supply and transfer lines during food processing.
14.Heating lines for the textile and paper industry.     
15.Heating supply lines in bakeries for batter mixing. 
16.Hydraulic lines in marine 
17.Light-duty hoses for transferring chemicals. 
18.Lines that supply milk carton manufacturing equipment. 
19.Lines within refrigeration units. 
20.Sealant lines used in canning beverages.
21.Steam lines for dry cleaning and laundry presses. 
22.Supply lines for spray painting. 
23.Transferring crude oil and other petrochemicals via hoses.

Because of their dielectric properties, PTFE convoluted tubes also provide additional safety for applications where static electricity builds up and requires dissipation. Convoluted tubing can additionally be produced with thicker walls when more robust tubing is needed, or with thinner walls to ensure better flow of fluids.
