snap-joint coupling78.



snap-joint coupling type 78, PN 20 >victaulic groove system<
Snap-joint coupling
Victaulic No. 78
Snap-joint couplings of type 78 were developed for fast disassembly.
The two halves of the housing are equipped with a hinge and a locking lever for easier assembly.
Design considerations
The couplings are not designed for eccentric loads.
