The fine line between victory and defeat

On every kilometer of a race track it becomes clear how important a well-balanced brake is. Perfect control gives you the confidence you need because the difference between a good rider and an average rider is that one has speed under control, the other does not. That's why here at HEL Performance we make the best lines, so you have the control you need to perform at your best.

Every HEL Performance line is combined in-house with the best stainless steel fittings and then crimped.

With us you will find the right brake line kit for your vehicle and get what you expect, high-quality materials, excellent performance and visually outstanding brake lines.

HEL brake lines eliminate the spongy feeling you get from rubber lines.

We only use stainless steel components for all parts of our lines and not steel connections like other manufacturers, which rust over the course of their service life and again pose a safety risk.

What's Stopping You?

 

Lens seal, brass, 8x3.8 mm, 3 mm bore, 2x120° convex sealing cone.

The lens gasket is suitable for connecting certain fittings to one another. It is often used for connecting to metal lines.

Please note that the connector blocks in HEL Performance’s ABS line kits are designed such that this lens gasket is NOT required. With HEL Performance, the sealing cone is already integrated into the connector block. By its very nature, a lens gasket must seal on both sides. However, if the sealing cone is already present in the connector—as is the case with HEL Performance—only one surface needs to be sealed. In our view, this provides greater operational reliability. It is also likely easier to handle during installation.

In some applications, however, a lens gasket is required. That is why we offer it as an accessory.

Package contents: 1 x lens gasket
Material: Brass
