Quluxe Rubber Studs Shock Absorber Anit-Vibration Isolator Mounts for Mini Split Heat/Water Pumps, Air Compressors (Pack of 4)

Lower the exhaust fan vibration quite a bit - good quality

The only issue I have with this product, is you get to a certain point of tightening, and even though it isn't quiet tight enough, the screw gives and starts to spin inside the bushing, with no way to hold the other side

I used these to bolt down a mini split air conditioner a few months ago. I used locktite on the nuts so they wouldn't back off. They have shrunk down a little bit in the heat, but a little tightening and they're back to snug. I think they'll last for years.

I don't really know what these are for. It's just allthread with a bumper-looking piece molded to it.Any vibration from an engine would bounce on the bumpers but would loosen the nuts.Only $10 so not worth it to return...I'll use them for something.Just know what you're getting.

I can barely hear my water pump run. Most vibrate on the floor.

Decent product!

I was hoping that they would be a vibration Damper. I mounted a generator to my travel trailer with these but they didn't stop the vibration through the trailer. Instead of being two studs molded into the bushing it was a rod clear through the bushing which did very little to stop any vibration.

bolts are to short to make it threw the block to put a nut on. not even close
