*Stahlbus quick release coupling*

With stahlbus quick disconnect couplings you can break any type of hoses and hydraulic lines without spilling any fluid. They work absolutely tight so no air can get in. Specially chosen o-ring seals make them ideal for brake fluid, hydraulic fluids, Diesel, Ethanol, mineral or plant oils, cooling liquids and gasoline.

Stahlbus offers two lines of couplings:

• S-Link bayonet type
• S-Link pull type.
  Depending on the construction they withstand pressures up to 200 bar.

Providing the same flow, the couplings use up to 20% less space compared to standard products while at the same time offering a bigger flow diameter.

The complete handling mechanism of the S-Link pull type has been designed for single-handed use. No separate activation of the locking/unlocking ring is necessary when connecting or disconnecting.

Different joint dimensions are available within a short time frame with a small additional cost.

Stahlbus bleeder screw

The constant opening and closing of conventional bleeder screws during the bleeding process wears the aluminum thread in the cylinder (e.g. of the caliper) in such a way that clearances start to appear with time. At the worst, the cylinder may become defective. Another disadvantage is that the thread of an opened bleeder screw does not seal.

The Stahlbus® Bleeder Valve is different, because it consists of two parts with a non-return function. During bleeding and filling, only the upper part with the integrated O-ring seal is unscrewed. This prevents both air and brake fluid or hydraulic fluid to ingress through the opened thread. In addition, it is no longer necessary to open and close the system synchronously due to the non-return valve. In case of pressure loss the Stahlbus® Bleeder Valve closes independently until the next bleeding pressure is built up.

Thus, the complete system bleeding is achieved within minutes. Single-handedly, without assistance.

Hydraulic systems are easily changed to our Stahlbus® bleed system by replacing the former bleeder screw by the Stahlbus® Bleeder Valve. It is inserted into the cylinder once and remains there
