Overview

Smoothbore

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

Smoothbore Cut Lengths

Aflex Hose are also able to supply Smoothbore Hose in ready-to-assemble pre-cut lengths, with the braid wire at the ends annealed and cut so the cut ends do not flare out. This makes it easier to slide ferrules on to the hose ends during assembly.

This can be applied to all sizes up to 1” bore Smoothbore, Single Braid hose for minimum quantities of 500+ lengths. Minimum cut length 60mm (23/8”), lengths cut to an accuracy of 1.5mm (1/16”).

External protections available – see braid, covers and end fittings page.

Smoothbore assembly length and limitations

MINIMUM LENGTHS DO NOT INCLUDE FITTINGS.

Hose length + end fittings = Total hose assembly length (sealing face to sealing face)

Lengths made to customer requirement.

Tolerance +11/2%/-0 %. Closer tolerances available to special order.

End Fittings

Large range of ‘standard’ end fittings available.

Special order—non-standard grades of SS or materials such as Hastelloy or Monel.
