I was pleased with the help I received in pinpointing what I needed to order and the prompt delivery once that was established. As a matter of note, my order was for (4) filters. This is for a Pelican water filter system. Pelican's advice before they closed, and the configuration of the equipment calls for (2) O-rings to be replaced each time you change a filter....recommended every 3 months. I was told that the kit only came with (4) O-rings instead of the (8) I was used to receiving in the past. Also in the past four small packets of silicone grease used to come with a set of (4) filters. I was told that the grease was not available. Lo and behold! When the package arrived, there were (8) O-rings, and (4) packets of grease. Thank you. Hopefully this will be repeated in the future.
