Review on VizGiz Waterproof Weatherproof Connector Extension by David Bar

They have a cut in the silicone rubber gasket so you can slide it over an already connected cable. Damn, they really got it right. I've come across waterproof connectors that come with cameras and you have to put the cable through a silicone grommet before adding the connector at the end. 90% of the time I would forget and I would have to cut the end and finish again. (in retrospect I think I could have just cut a slit in them. oh ok I got it right) they are high quality and worked great with my Blue Aperture machine and Dahua/Amcrest POE cameras.
