Up to the harsh conditions of the road: stainless steel couplings from Parker

The pneumatic and hydraulic systems in public transport vehicles are exposed to particularly harsh conditions, as are the lines and couplings that play a central role in these systems. As critical interfaces, couplings in particular have to meet the highest demands in terms of quality, safety and flexibility. Such as the Rectus products by Parker.

Public transport vehicle manufacturers and maintenance specialists have a huge responsibility in this regard. This is because personal safety, operational safety and reliability are of paramount importance when it comes to passenger transportation. These criteria apply to the engineering process as a whole, as well as to each individual component, such as the couplings which – as fixed, absolutely leak-proof and at the same time flexible connections at key points in the system of pneumatic and hydraulic lines – have to be able to withstand harsh conditions.

Successful combination of robustness and simple handling

The couplings in Parker’s Rectus series have been developed specifically for the extreme conditions found in vehicle construction. The use of high-quality stainless steel gives them robustness and longevity. It makes the couplings resistant to large temperature fluctuations and allows for a predictable maintenance schedule. The ingenious design also makes it possible to break the circuit in a quick and safe manner. All that is needed is to simply pull back the coupling ring by hand.

The right product for every application

The wide selection of Rectus stainless steel couplings caters to a variety of needs and applications in pneumatic and hydraulic systems. These range from the ‘low-leakage’ types to those that can be locked on both sides. These are used wherever leakage of the medium needs to be prevented or pressures need to be maintained during coupling and uncoupling.
