Audited Supplier Vehicle Braking Performance Automotive Custom Made Front Rear Kits DOT Compliant Braided Stainless Steel AN3 Brake Hoses Lines
We can produce the performance braided stainless steel braided brake Hose line assembly kits according to customers' samples ,drawings or description ,we have hoses and fittings catalogue ,you can chose the detail end fittings with detail size hoses and hose length ,then we can do the correct assembly line for you .
Improve vehicle brake performance and feel with DOT-Compliant Renn-lines. These Stainless Steel Braided Brake Lines provide a quicker, firmer, more consistent pedal response by maintaining consistent brake pressure. Additionally, stainless steel lines provide precision brake modulation, especially during threshold braking. The improvement in pedal feel is more dramatic on older vehicles where the factory rubber line may have softened and swelled due to age.
QDGY consist of a PTFE (commonly referred to as Teflon®) inner line that carries the brake fluid, which is then covered with a layer of stainless steel woven braid. The PTFE tube is very resistant to expansion under pressure and will not degrade from exposure to brake fluid.
The braided stainless steel provides support for the PTFE and the weave is extremely durable against incidental impact and abrasion. Next the stainless braided hose is coated with a clear abrasion resistant PVC cover for maximum protection against chaffing and strain relief devices reinforce end fittings. All fittings are engineered and machined for proper fit and durability. All necessary brackets and fasteners are included with each line kit. Sold as a Pair.
We can produce fitting according to your drawings or samples ,or your description .We have our design and research department to cooperate with you that to meet your any demond for your market development .We can accept usual practice fittings ,also we like the new fittings development and we have capacity to help you to research and develop the new products.
