Brake Line Material & Standards

This AGS NiCopp brake line uses a nickel-copper alloy designated UNS C70600 that meets SAE J1047 and ISO 4038. The tubing contains approximately 88.6 percent copper and 9.2 percent nickel with small amounts of iron and manganese. It provides the strength of steel with far greater corrosion resistance and has been used on European vehicles since the 1970s.

Installation Characteristics

NiCopp tubing is easier to bend and form than traditional steel brake lines, reducing the risk of kinking during routing. The material work-hardens as it is shaped, so installers should plan bends carefully and avoid repeated re-bending. Proper flaring tools for copper-nickel alloy are required to create reliable sealed connections without splitting the tube ends.

Suitable Applications & Limits

This 3/16 inch by 72 inch line suits automotive brake, fuel and transmission repairs where corrosion resistance is a priority. It is not intended for high-pressure hydraulic systems outside the stated standards. Buyers needing a different diameter, length or alloy composition should look at other options. The product carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm.

Questions about this item

How can I verify the brake line is correctly installed and holding pressure after fitting?

Pressurise the hydraulic system and inspect every joint for fluid escape; the NiCopp tubing meets SAE J1047 and ISO 4038 so it should hold without weeping.

What comes with the AGS CN-372 and what must I supply myself?

The package contains a single 72-inch length of 3/16-inch NiCopp nickel-copper alloy tubing; you will need flare nuts, a flaring tool and tube cutter for the ends.

Which alloy specification should I match when choosing this line for my vehicle?

The tubing is UNS C70600, approximately 88.6 % copper, 9.2 % nickel, 1.4 % iron and 0.8 % manganese — the 90-10 copper-nickel blend specified by SAE J1047.
