Speedway 3/16 Inch PVF Coated Steel Brake Line

Now available for your 3/16" brake line consideration is a new PVF Poly-Armour Poly-Vinyl Fluorine coated brake line. 

  • PVF coating is a highly durable 'plastic' coating that is 'baked and cured' to the line for a durable finish that provides a clean look and appearance with a dark olive green color
  • This provides extra protection from corrosion, debris, and road surfacing solutions
  • Also offers superior bend-ability without kinking and bends easier than standard brake line tubing
  • This makes Poly-Armour the easiest line to work with-period!
  • Underneath the PVF coating is a double-wall, low carbon steel, copper brazed tubing which meets all international and U.S. requirements for brake tubing
  • Considered a premium line, Poly-Armour hard line should be used on any vehicle that will see any type of harsh environment including snow, road treatments, salt, air, dirt/gravel etc.
  • PVF Poly-Armour coated line is the perfect choice for the racer for those weekend after race chassis washes week after week or any street rod fabricator wanting to utilize a hard line application for that beautiful finish that will last for years
  • Available in a 25' roll of 3/16" line
  • This line bends easily and smoothly with hand tools and can be flared with a 37° AN flaring tool, or 45° double flaring tool
  • Use in conjunction with our 3/8"-24 inverted flare male brake line nuts, or AN tube nuts and sleeves
