Powerhose is a DIY hose construction. We will supply braided hose cut to length and banjos with nut and olive to fit the ends of the hose. We recommend using mandrel ( VT62 ) tool to open up the braiding when fitting the banjos to the hose, and to tighten the socket nut. Without this using this tool your brake hose is more likely to leak. A demonstration video for making Powerhose lines can be viewed by clicking the Powerhose link above.
Why should I fit braided hoses?
Rubber brake lines ¿ often OE fitment on motorcycles (and cars) ¿ perish, harden and crack over time. This can allow the absorption of water into the brake fluid, reducing the efficiency of braking system and putting other components at risk of corrosion.
As rubber brake lines age, they are also prone to expansion under pressure, reducing braking efficiency.
Braided steel brake lines eliminate expansion and water absorption, and will last the lifetime of the bike.
What is TUV approval and are your brake and clutch lines TUV approved?
Yes. Venhill Powerhose Plus lines have been formally tested and approved by TUV Rheinland. The test is in accordance with VSS106 standards. All Powerhose Plus lines are made to this standard. Venhill also has ISO 9001:2000 certification.
TÜV Product Service is an independent test body, which provides testing, certification, qualification, training and consultancy services to a range of industries. It has some of the best test facilities in Europe, and is recognised for independently testing and certifying a huge range of products, to make sure they meet the strict safety and quality standards required for sale and use worldwide.

Are your brake and clutch hydraulic lines DOT approved?
Yes. In addition to the TUV approval, our hose specifications have been sent to the United States Department of Transport and received authorization to claim that Venhill hoses meet the requirements as set forth by the DOT in accordance with the United States Federal Motor Vehicle Safety Standard No. 106, "Brake Hoses".
The DOT does not certify products. Compliance with the requirements is ¿self-policed¿ by the manufacturer. Manufacturers submit product specifications to the DOT and receive permission to claim that the product meets DOT requirements. Whether or not the actual product you receive meets those requirements is up to the manufacturer. Every Venhill hose is built to the same specifications that were sent to the DOT, thus every hose meets (or exceeds) DOT standards.
How tight do banjo bolts need to be?
The recommended torque settings for 10mm banjo bolts are as follows:
Min 19Nm - Max 25Nm
For smaller diameter bolts such as the 5/16th" BSF (British Standard Fine) thread, the setting should be reduced significantly.
Where should I use my Copper Washers?
Copper washers should be used on each side of banjos before tightening the banjo bolts. There is no need to use copper washers with adaptors unless the hole is not sufficient to house the entire thread of the bolt. If you are in any doubt as to how to correctly fit and bleed your brake lines, we recommend contacting your local motorcycle workshop for fitting.
