Quick connect system 203

The VOSS quick connect system 203 enables a fast and safe assembly of nylon tubes with smaller diameters in compressed air and fuel systems. It is available in a variety of designs: as a single component or integrated in valves, manifolds and multi connectors.

The market standard for air suspension

In pneumatic spring systems, it is important above all that the system is leak-tight, and that the assembly space occupied by the components is kept as small as possible. At the same time, assembly should be simple and fast.

The integrated version of quick connect system 203 offers the ideal solution for this. This subassembly can be screwed directly into a unit which is equipped with a corresponding special port.

The system-specific special port is now the standard in vehicle construction and, with its overall contour, covers the most important functions of the VOSS quick connect system 203: the optimum thread sealing, the functionally reliable assembly space for the grip ring and the tube stops for the nylon tube.

We take a holistic approach. Beyond connection systems, VOSS provides endless options with tailor-made line assembly.

Auxiliary lines

In addition to the brake, there are several other functions in commercial vehicles which are controlled by the air brake system. These include the air suspension, clutch control line, car suspension, air-suspended driver seats and the air horn. To fulfill the respective functions, the line system and the connections must be secure and tight, and the assembly must be simple and fast.

Quick connect system 246 ^NX

Standard solutions (e.g. SAE and VDA) are often used to connect fuel, SCR and thermal management lines. For example, when it comes to responding to tight assembly space or assembly conditions or meeting special requirements, they quickly reach their limits. For this we have developed the quick connect system 246^NX, which is not only suitable for special conditions of use, but always offers the best solution.

Quick connect system 203 ^N

The VOSS quick connect system 203^N enables a fast and safe assembly of nylon tubes in pneumatic spring systems. Compared to the standard system 203 made of brass, it offers a plug body made of aluminum and simplified handling.

Multi connectors

Multi connectors connect several consecutive connections in a single assembly step. They can be used as intersections, for example in bulkhead fittings, or as component connecting ports. The main components are individual two-part or multi-part plastic plates as well as plugs and couplings which lock into them.Multi connectors are intended to simplify assembly and make it less susceptible to faults, reduce the number of assembly steps and thus drastically reduce assembly time and increase safety.

Manifolds and connectors for compressed air

Manifolds and connectors for use in air brake systems are an integral part of the VOSS plug-in system programs (e.g. Systems 203 and 232). They are used in brake and auxiliary systems of commercial vehicles as well as in passenger car air suspension.

CategoryManifolds and in-line connectors

To produce a leak-tight connection of nylon tubes and quick connect systems, it is necessary that the nylon tubes are cut to length straight, burr-free and clean. In addition to the duty of care when cutting to length, this is ensured by the quality of the tools used. Suitable tools, which ensure a correct connection, must also be used for the assembly of nylon tubes on the mandrel of quick connect systems. To ensure that VOSS products are always assembled with process safety in mind, we offer appropriate assembly tools.
