Rubber Isolation Pads Thick Rubber Washers 1.5 Inch OD 0.5 Inch ID 0.4'' Thick Mechanical Vibration Damping Pads Anti Vibration Isolation Isolator Washer(8 Pcs)

Nice, thick rubber washers, just the right durometer for vibration isolation. Put these on top of the vibration isolators, on the outside of the mounting feet, just under the bolt head, with a big fender washer, for that extra mile of vibration isolation. Mr. Heat Pump purrs like a kitten. Can't even tell it's running, inside the house, a foot away. All rubber, all the way.

I bought the 4 pack of these, and they worked perfectly. I used them for my engine on my go kart and the results were very impressive, very good product for heavy vibration and movement. I would order more than you want because the rubber won't last forever but I do believe they will last a descent time because the rubber is great quality. Great product. I will be buying more of them.

Used as spacers. Worked great.

Worked as advertised, worked as needed. Reduced vibration transfer substantially... seams like 70>80% at least.

Great for isolating an air compressor on a dental unit.

They are well built. The amount of noise reduction they will give depends on your system. The effect was small in mine.

They are large and thick which meet my criteria. I put them between each layer of my audio rack and then I put speaker spike pad on top of these rubber rings for vibration adsorption; so far so good.

If you needs rubber washers, I haven't found anything to complain about, with these.
