The 1s nipples were too small. The 2s were too large. There needs to be a size in between.

The parts ordered were exactly what I wanted. The quality and looks are very good. These rubber items take strong pulling to set in place without shape distortion or stretching past the point of elasticity. Now I need to wait 25 years to report on longevity.

Size matters. A #1 is appropriate for up to a single 12 ga. wire (or 3-4 22 ga.). A #3 would work with a battery terminal/cable.
Quality is good.

They made of good materials and dimensionally accurate. The black is black and the white is white, but the red is as shown - kind of a brownish orange. I would prefer a pure red nipple, but that does not diminish the value of these for insulation protection of terminals - which they do well.

Great quality and a perfect replacement item for the disintegrating old boots on your contactors/battery/etc. Get a couple of each size. Try -4S for battery terminals and contactor power terminals and -1S for most smaller posts such as magnetos and contactor coil posts.

Much appreciate ACS stocking these things are they are an obscure item tough to find elsewhere.
The quality of the rubber seems good. I stock a few of each size as the price is right and then I have the right one available when I need it. These are not the sort of item you want to put the project on hold while you order one.
