Product overview of the Bleeder valves

The patented stahlbus® bleeder valve is available in different designs. The valve consists of the adapter part (lower part) and the actual valve (top). In the various types of construction, the adapter only (lower part) are different. For the industrial sector we have, depending on the used medium, special O-rings, such as Viton for hydraulic oil.

Auxiliary vacuum filling and bleeding device


Bleeding brakes bleeding device

You want to find a quick, simple and clean way of refilling your hydraulic brake / clutch system?

Then you may go and buy an expensive vacuum bleeder device. Or you may use our simple auxiliary refill and bleeder device.

New filling / Bleeding / Change of Brake fluid

Just fill your compensating reservoir with the hydraulic liquid and suck the liquid into the brake / clutch system with the vacuum bellows. Then quickly bleed  the system with the stahlbus® Bleeder Valve, and then you may start again. With that, also the last drop of brake fluid finally remains where it belongs - in the hose. It is a very good tool for bleeding brakes / clutches and for the filling and washing the brake / clutch or hydraulic lines.

Content: vacuum bellows 50ml or 150ml, hose adapter, approx. 30cm transparent silicone hose

Connecting tool

Bleeding brakes connection toolFor the absolute tight connection of filling and bleeding equipment to the Stahlbus bleeder valves we have developed in collaboration with the well nowned producer HAZET a connecting tool.

This tool sits absolutely tight on the patented stahlbus® bleeder valve.

With a torque wrench you can close and open the valve.

When removing the tool the built-in check valve prevents leakage of fluid from the connected hose.

This tool is designed specifically for professional workshops and industrial applications and designed for continuous use such as bleeding brakes and clutches.HAZETBleeding brakes connection tool
