Hi Pete,

That depends on the brand of the TE probe, and the size. I sell ILEC TE
probes in both 6 mm and 8 mm diameters. The o-rings are smaller than those
dimensions. You can see them he

Hi, got a dumb question. The O-rings on the TE probe of our L-23 are
shot. Of course I forgot to measure them last time I was at the field,
so I hope one of you might know what size to get.

Thanks

Pete
