Reliable and clever connector solutions play a critical role, especially in complex circuits in automation and compressed air technology. L- or block manifolds with two or three connections are used between apparatus and tools, tubes, and hoses. These fittings allow nearly all imaginable circuits for all imaginable application scenarios. Thoroughly thought-out concepts are required, primarily because of increasing demands on circuit functionality and decreasing installation space resulting from miniaturisation. Multifaceted angle and distributor elements are indispensable for optimal use of pipe segments and flexible conduits that only allow a limited bending range.
