stahlbus® quick disconnect coupling

Compact design, extremely light, 'Made in Germany'

NEW: CNC-machined quick disconnect couplings.
New to the product range since summer 2010 are unique stahlbus brand quick-release couplings. The CNC machined components comply with the highest aviation industry specifications and are suitable for fuels (mineral and biological basis), brake fluid and compressed air.

stahlbus® bleeder valve

100% braking performance due to perfect bleeding

Our patented bleeder valve radically simplifies the bleeding of hydraulic lines. To ensure that completely deairiated fluid is added, we provide a broad range of solutions specifically adapted to suit the demands of automobile manufacturers, workshops and race teams.
This includes special hoses, tools and electronic high-performance filling systems suited to each respective vehicle

stahlbus® oil drain valve

The intelligent way to change oil

Use our drain valve to change oil with absolute safety and without pollution.
The advantages at a glance:
• Easy handling thanks to quick release fitting
• No danger of burns from hot oil
• Oil sump threads are protected
• Twin leakage protection (protective cap and valve)
• Connection to suction pumps possible
• Metered drain for taking samples / overfilling
• O-ring prevents losing protective cap


We attach great value to our products being tested under genuine racing conditions. The results from these tests are valuable help for further product development.

The stahlbus factor

We elected to pursue uncompromising quality and the satisfaction of our customers proves us right. We think processes all the way through. For this reason customers can expect the greatest levels of performance from our products.

Made in Germany

We attach the greatest value that our products are produced exclusively in Germany. Only in this way can we permanently fulfil our high quality demands.


Our brake bleeder valve improves braking performance permanently and increases driving safety. The oil drain valve ensures a clean oil change without spillage or splashing and prevents thread damage. The quick release coupling ensures both the rapid and safe replacement of brake system components during racing

Oil drain valve – installation

At the next oil change simply unscrew the original drain plug and replace with the stahlbus drain valve.

Audi A3 – racing

Thanks to the stahlbus bleeder valve find and use exactly the same braking point every lap.

Porsche GT

A beautiful car with an ugly rubber dustcap! Time for a change?


Each and every motorbike rider attaches great importance to braking performance. Our bleeder valve guarantees a stable pressure point and gives riders the peace of mind that they will come to a standstill safely and in good time. Fluid is now changed easily and without spillage or damage to threads thanks to the oil drain valve.

Banjo bolt

An increasing number of brake calipers are equipped with banjo bolts as standard, saving the manufacturer an additional bore for the otherwise separate bleed nipple.

Bleeding the master cylinder

Bleeding brake master cylinders is a difficult task. Fluid spillage here is certainly not desirable!

Bleeder valve

Our standard, multi-purpose product – the stahlbus bleeder valve. Change brake fluid easily, safely without spillage and more specifically completely free of air!


The broad spectrum of hydraulic controls found within the aerospace industry demand absolute system reliability. The less air trapped in a system the safer and more efficient is the function of brakes, steering gear and all other hydraulically operated equipment.

Production line applications

Well-known glider manufacturers Stemme, Schempp-Hirth and Alexander Schleicher use stahlbus bleeder valves as standard equipment.

Endurance testing

The stahlbus bleeder valve also reveals no weaknesses under the toughest conditions.


Stahlbus products simplify, accelerate and make changing oil and lubricants, such as hydraulic oils, cleaner and splash-free. For example, typical applications include hydraulic units in CNC turning and milling machines, presses, injection moulding machines and bottling plants in the food industry.

CNC turning and milling machines

Stahlbus oil drain valves also ease the regular changing of oil on all types of machining centres.

bottling plants

The bottling of food in particular demands clean solutions when bleeding pipes and lines. Our titanium products are perfectly suited for special requirements.

Hydraulic installations

The stahlbus product range provides crucial benefits during servicing and maintenance where the convenient and rapid disconnection of pipes is made without fluid loss.


Since environmental regulations will become increasingly strict and restrictive to prevent pollution our oil drain valve is perfectly suited for use with marine vessels. Changing oil can now be made completely clean and without risk of pollution.

Changing engine oil

Changing engine oil without spillage on a boat is often very difficult due to the confined space. Our oil drain valve is a great help – particularly when used in connection with an external pump

Topping-up gearbox oil

Adding gearbox oil is often difficult to accomplish. For this purpose oil can be added using our oil drain valve with or without external pump.

Fuel and cooling water pipes

Stahlbus quick release couplings ensure the splash-free and clean separation of cooling water and fuel pipes when carrying out repair or maintenance work on engines.
