Re: Plugs or insert covers for Blue Ox Tow car

A friend used a plumbing part, from a hardware store.
Label on the cap per the photo he sent me last night, says "Pipeconx by Uniseal 1 1/2" size, made in USA, Evensville Indiana, Plastic or Cast Iron"
PIPECONX - Universal Pipe Connectors
Note that the part comes with a band clamp, he reports that he stopped using the band clamp as the rubber part is tight on the Blue Ox tube.
So it would seem any cap for anything 1 1/2" would serve to keep the inside clean.
