7000 - Push-in fittings for braking systems

Download technical datasheet

The push-in fittings (series 7000), made of brass, has been designed to be used with polyamide 11/12 or polyester elastomer tubes on pneumatic circuits of auxiliary installations and heavy-duty braking systems and trailers. It is a ready-to-use safety coupling, requiring no tools for coupling with the tube. All that is required is to manually snap the tube into the coupling housing. The assembly time is thus extremely reduced compared to traditional couplings with cutting rings. A reduction in assembly time of around 70-80% can be estimated. The tolerances of the pipes used must strictly comply with ISO 7628 and DIN 74324/73378. The temperature range of the quick coupling is -40°C/+100°C. Sealing under these conditions is guaranteed by a special mixture chosen for the O-rings.
