With chamfered connection elements, the clamping edge grips underneath the chamfer, thereby increasing the clamping effect of the cap.

Better clamping effect

The newly developed stabilising edges significantly increase the overall clamping effect. This is especially important in connection elements without a chamfer, where the effectiveness of the clamping edge is reduced.

On a flat base, the sealing lip, the elongated variants of which also cover washers of various heights and diameters, offers the best possible protection against spray.
