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.

Well made aircraft grade. The hardest part is figuring out which sizes are needed. This item has a useful table to help.

Good physical coverage that will decrease the likelihood of unwanted electrical contact with surrounding metallic objects. Pick the correct size for wire and post. The cost is low enough to buy multiples.

Positive vs Negative on my battery is not super easy to see in my rather dim hanger lighting, so when I ripped I white boot I went back with black and red (orange, really) boots.

These are the trick for making secure electrical connections. Kinda hard to find too.

Cowans A Verified Purchase

Silicon Nipple MS25171-3S Red

perfect fast shipping

came just as expected!

Fits properly over terminal on Concord RG-35AXC battery and provides proper electrical separation.

I use them for the starter cable on Marine generators

Great product, good price

Needed these electric terminal nipples to replace the old ones on panel. Of high quality and perfect for the job.

Electric nipples of very good quality. Perfect for my project

Exactly what I needed on the Generator and battery.

Received as ordered

5 stars. I used 4ea ACS red silicon nipples & ACS lugs on 2ea batt+ cables.

I could gush about how great these guys are, instead, Ill just say Id all but given up finding some of the items I found here. From the prices on these near impossible items, its clear , they are not trying to retire from one sale. You wont be disappointed with the parts or service.

these are a good product, have used before.

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.

Perfect Fit!

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.

I ended up buying all four available sizes, keeping them in stock for when I need them. Fit and function are good!

Just what they appear to be. Can be stretched a bit for a snug fit.

They are a hard to find item. But the ones I got from Aircraft Spruce really work great. Thank you.

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.

Excellent product that is difficult to find locally, but Spruce is a prompt shipper. Thanks guys!

Bought one that tore apart taking it out of ACS plastic bag. My first thought was they found out exactly how thin and how cheap they can make these now ! Sent it back to ACS for replacement
