Does this seal work with any window air conditioner?

It fits most window units because you cut it to length and compress it into the gap. It works best on gaps up to about 1-1/4 inches wide.

Do I need adhesive or tape to install it?

The strip has no adhesive backing. Most users wedge it in place or add their own tape to keep it from shifting.

It mainly cuts vibration rattle and seals air gaps, which can lower perceived noise. It won't soundproof the compressor.

One strip is 42 inches long. Measure both side gaps and the top gap before buying, since wide windows may need two.

Yes. The foam works as general draft and insect stripping on any gap of similar width.

Ordinary scissors cut it cleanly. Trim slightly long so the foam compresses for a tight seal.
