Here's a sample of what our customers have to say about Cunifer brake line:
Dear FedHill: I felt compelled to write and say thanks for the great product and service. The order process was easy and the shipping time extremely fast. As a commercial snowplow company, we’ve learned the necessity of having brake repair supplies in stock at all times. Thanks to FedHill we have had 100% uptime and no brake related failures at all this season. Your product is so easy to install, my mechanics are doing preventive maintenance on brake lines, something that was never done before. In short, your product has made my business easier to run and more profitable in one easy step.
Thanks for providing a great product. King's Home Service
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 A1-3 nut, the "-3" indicates it would be used with CNF-3 (3/16") tubing.
The nut dash size must match the tube dash size.
