The entry-level replacement line in the AGS brake line category is still an excellent choice for aftermarket fluid transfer line repair and replacement. The steel lines and tubing are constructed with safety and longevity in mind. The tubing is produced by wrapping copper-coated steel around itself twice to form the tubing. This double-wall tube is what provides the strength and structural integrity to withstand the extreme pressures required, yet still remain pliable enough to be formed and bent to the shapes required to be routed beneath the vehicle. The finished tube is fused and zinc-coated to provide excellent rust and corrosion resistance as well.
Poly-Armour® has become the new standard in brake line replacement over the last several years. Surpassing all competitors as THE choice for both professionals and do-it-yourselfers when it comes to brake, fuel, and transmission line repair. Poly-Armour® is different from anything else on the market due to its PVF or Poly-Vinyl Fluorine coat. This coating is actually a highly durable 'plastic' coating that is 'baked and cured' to the line. This provides extra protection from corrosion, debris, and road surfacing solutions. It also offers superior bend-ability without kinking. That makes Poly-Armour® the easiest to work with line - period!
NiCopp® is a nickel-copper alloy brake tubing that meets SAE Standard J1047 and ISO 4038, meeting all international and U.S. requirements for brake tubing. This alloy is approximately 9.2% nickel, 1.4% iron, 0.8% manganese, and 88.6% copper. Under the UNS system, this alloy is designated as UNS C70600. NiCopp® therefore has the strength and structural integrity of steel lines, but with the added benefit of being much more corrosion resistant. NiCopp® is also easier to bend and form than steel tubing. Nickel-copper, commonly referred to as '90-10 copper', has been used on several European vehicle brake systems since the 1970's, including: Volvo, Audi, Porsche, and Aston Martin.
