Fittings and accessories in almost unlimited selection

The design of complex centralized lubrication systems is often not the only challenge. The structural conditions of systems, machines and vehicles also require a high degree of flexibility in screw connections and pipes for lubrication systems, particularly with regard to sizes and shapes.

The decisive function of cutting ring fittings is the fluid-tight connection of pipes within central lubrication systems. By tightening the conical union nut, the cutting ring is cut into the tube wall, which creates a tight form fit. They are divided into different series in terms of nominal and operating pressures, as well as line cross sections.

Push-in fittings offer a clear advantage in terms of assembly time compared to cutting ring fittings, but there are restrictions regarding their maximum operating pressures and piping materials. When connecting to metal pipes and pipe sockets, it is imperative to pay attention to an existing claw groove, which prevents it from "slipping out". Because of their reusability, connectors offer further great benefits.

When selecting the suitable lubrication line, the prevailing pressures, ambient temperatures, equipment regulations and lubricant compatibility also play a major role. In the case of poly pipes with a wall thickness of <1.5 mm, care should be taken, for example, to use push-in sleeves to prevent the pipe from being compressed.
