PTFE-lined hose for automotive and general purpose applications
Smoothbore hose comprises a straight PTFE tube liner and a stainless steel outer braid. It is the basic PTFE hose design being used successfully in many automotive and general-purpose applications. Other applications include use with high-pressure steam and gasses, refrigerants, hot oils, and other hot or corrosive fluids.
Features and Benefits
- PTFE-lined high pressure hose
- Temperature resistant
- Chemical resistant
- Self-cleaning

Temperature and Pressures
HPG Specification
- Temperature affects the maximum working pressure (MWP) as listed above, so for temperatures above 130 °C reduce the MWP by 0.75% for each 1 °C / 33 °F above 130 °C / 266 °F. Example: at 180 °C / 356 °F, reduce the MWP by (180 – 130) x 0.75 = 37.5%
- Pressure ratings above 100 Bar (1500 psi) only apply for the transfer of non-penetrating fluids. If gases or penetrating fluids are used in the application, or used during pressure testing at pressures above 100 Bar, HPG grade hose is required.
For applications where gases are used in the hose at high pressures, or testing procedures above 100 bar (1500 psi) it is necessary to specify a HPG grade PTFE liner tube. HPG grade is also required when high pressures are applied to penetrating fluids.
HPG grade tubing is achieved by subjecting the PTFE tube to certain special processes, commonly known as “post
sintering”, which increases the resistance of the material to penetration and porosity development by gases in service.
This specification requires that when compressed air or nitrogen is applied to a sample length at a pressure of 275
Bar (4000 psi) for one minute, then the pressure rapidly broken then re-applied for a total of 10 cycles, the sample
must not show signs of excessive diffusion when finally gas tested under water.
Pure gases do not generate static charges, HPG liners are rarely required to be anti-static, but on such rare occasions, a special “inner layer” AS grade is used.
All sizes and types of Smoothbore hose PTFE tube liners can be supplied to HPG quality. However, we would always recommend that HPG hoses are supplied with a HW (Heavy Wall) for maximum performance.
LINERS
Natural
This liner can be used when there is no risk of electrostatic charge
Anti-Static
This liner is essential in applications where there is a risk of electrostatic charge
HPG
This liner is ideal for high pressure gas applications or testing procedures are above 100 bar
AS Liner
This liner consists of an anti-static internal layer of the PTFE with a natural outer layer, which provides the required static discharge properties.
BRAIDS
Stainless Steel
High pressure, high temperature applications
Aramid
Lightweight, high pressure applications
PPS
Ultra lightweight for low pressure applications
Combination Braids
Combination of different braid materials to provide completely bespoke solutions.
