Well after years of use the O-ring has broken on my reeflo orca 200 protein skimmer and I can’t determine the size. It’s the one at the collection cup /neck. I know that it is not standard after trying a couple different sizes. It’s closest to 3/16” thick. I’m thinking it is 130mm (inside dimension) x 4mm (thickness). Is this correct? Or What size do I need? I really need to get my skimmer back up and running on my 350 gallon tank.

Not entirely sure. I am checking on it with the factory and will respond back. In the mean time you can make your own by fusing or cutting orings to fit the skimmer cup. Just make sure the cuts are clean and straight and glue them together with reg. superglue.

Thanks for checking and I’m anxious to find out what size it is. I would try to make a temporary one but I have not been able to find 4mm (thickness) locally. Also for some reason the o-rings that are sold as 3/16" are .210" not .1875" so I can't use them as they are too thick

The oring is 4mmx 132ID which is the same size as our Classic 250int.

Thanks. just a quick question. If the "neck' is 130mm wouldn't 132mm be to big because it would leave a 1mm gap all the way around and allow water to get out? or maybe the grove that holds the oring compresses the oring to make up that gap.

Well the oring is inset into the acrylic ring so there is a bit of pressure against the oring to seal and hold the cup in position. Would you like me to see if we have one in stock?
