Anti Vibration Rubber Isolator Mounts with Studs Shock Absorber, M8-1.25

If you’re installing a mini-split and wall mounting it, I’d highly recommend these. I bought a 12k BTU mini-split and installed it on my exterior office wall. It’s stucco/styrofoam/OSB. I anchored to the OSB as the mounting using stainless toggle bolts. I used the 1/4” vibration pads that came with the mount. After installing, there was a fair amount of vibration and droning harmonics vibrating my office wall. I could actually hear it outside of my home office. I decided to pick these up and replace the rubber pads. The problem I had was I had to suspend and also raise the condensing unit to fit these. After a little creative work I got these installed and they’ve made a huge difference. I can hear the compressor start up but once it’s running I cannot really hear or feel the outdoor unit running. These are pretty soft mounts, but they work great for this application. Moral of the story is, install these up front if you want to reduce the chance of vibration transferring to whatever structure you’ve mounted the mini-split to. Two pics show these mounts newly installed while the third shows my original install.

These vibration dampeners are fantastic. I recently installed a mini split unit and had to mount the compressor to the wall outside. When the fan turns on it hits a harmonic frequency that vibrates the inside wall just enough to where it sounds like a large truck is idling outside. The vibration was driving me crazy, I tried numerous dampeners to try and eliminate it and none worked as well as this. I installed these yesterday and it has completely eliminated the vibration that was transmitted to the house and no longer makes a sound.Previously I tried cork, foam, and hard rubber dampeners, but none worked. As an extra layer of dampening I put a few rubber washers between the metal washer and the bracket for the compressor. I would highly recommend these.

These rubber isolators appear to be well constructed with good quality material. It would be helpful if this isolation mount (and all other similar devices) had some weight rating shown in the specifications. For example: X kilograms maximum weight, Y millimeters compression with rated weight.

Bought to use as a standoff for mounting a LED light bar on my side by side. Good product but in the end I didn't need them.

Simple to install works great. Minimised vibration noise in my garage, well worth purchasing these. Very happy with outcome.

I used them to mount a generator on my camper. It really isolated the vibrations well.

Too squishy, not sturdy enough for my needs.

Works great with my new air conditioner
