Tight-Grip Push-In Bumpers
A ridge on the stem provides a tighter grip than other push-in bumpers. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.
Bumpers with a hard and medium-hard rating withstand high levels of impact. The harder the bumper, the more impact it withstands.
Polyurethane bumpers have better abrasion resistance than SBR and plastic bumpers. They won't become brittle and crack when exposed to ozone. They're also nonmarking.

Compressible-Stem Push-In Bumpers
The stem on these bumpers compresses to fit into tight holes. Push the stem into a hole for quick installation. These bumpers are commonly used as feet on instruments and bench-top equipment to keep them from sliding. They're also good as spacers between sheets of material. Also known as stem and grommet bumpers.
Bumpers with a medium-hard rating withstand higher levels of impact than softer bumpers.
SBR bumpers have good abrasion resistance.
