This might even be water applied to the seal just before it is pressed into the groove. The effect is even better if some washing-up liquid is added - this improves lubrication. Otherwise, there is a risk of the locking lip of the Profile not clicking into place under the inner edge of the Groove, and this will result in the Profiles slipping out later due to the stresses in the material.
