Conductive PTFE Hoses
Different with nonconductive version, conductive PTFE hoses are those that have a conductive resin liner made of carbon black, which imparts conductivity to the PTFE material and allows them to conduct electricity.
Like the conductive PTFE fuel hose, the conductive lining provides a path for static electricity to dissipate from the hose, preventing the buildup of static charge. The buildup of static charge can be dangerous in certain applications where a spark could ignite the fuel and cause an explosion, which makes the conductive liner ideal for use in PTFE fuel line running gas, E85, methanol, etc.
The carbon black liner is applied to the PTFE tube during the manufacturing process, ensuring uniform conductivity throughout the length of the hose.

Conductive PTFE Hose Manufacturing Process
Polytetrafluoroethylene (PTFE) Resin: Choose high-quality PTFE resin for its excellent chemical resistance and thermal stability.
Conductive Material: Integrate conductive carbon black to ensure the hose is electrically conductive.
Pre-forming: Create a pre-form of the PTFE material through a ram extruder.
Extrusion: Feed the pre-formed PTFE into an extruder to shape the hose. The extruder applies heat and pressure to form a continuous hose with the desired diameter and thickness.
Reinforcement: For added strength and durability, braid the exterior of the PTFE hose with stainless steel or other reinforcement materials.
Inspection: Conduct thorough inspections of the hose for uniformity, dimensional accuracy, and conductivity.
Testing: Perform electrical conductivity tests, pressure tests, and chemical resistance tests to ensure the hose meets industry standards and specifications.
Install a sample of Teflon assembly tubing into the test equipment, gradually increase the pressure in the tubing at a constant rate, and record the highest pressure value reached before bursting
End Fittings: Attach end fittings, such as flanges or couplings, to the hose to facilitate easy integration into systems.
Packaging: Carefully package the static-dissipative PTFE hose to prevent damage during transportation.
Labeling: Label the packages with necessary information, including hose specifications, batch numbers, and handling instructions.
