1/4" Brake Line and Nuts

Cunifer is a seamless, copper nickel alloy DOT approved brake line used for OEM and replacement brake lines, fuel lines, power steering and cooling lines. Corrosion proof and easy to install high pressure hydraulic tubing for the harshest environments. All of our tubing conforms to hydraulic brake tubing specifications SAE J1650, DIN 74234 and BS 2871.
 
 
All nuts are steel except where followed by ss (stainless steel) or br (brass)
Nuts will vary in color.
The number after the dash in the part number indicates the tube size to be used with that nut.
-3 is 3/16", -4 is 1/4", -5 is 5/16", -6 is 3/8" , -8 is 1/2"
For example the A2-4 nut, the "-4" indicates it would be used with CNF-4 (1/4") tubing.
The nut dash size must match the tube dash size.
