Push these flexible grommets into place to protect wire, cable, and cords by turning rough-edged and uneven holes into smooth, insulated holes. Commonly used in metal panels, they also damp vibration. All of these grommets have a medium hardness rating to offer a balance of cushioning and impact resistance.
SBR grommets have good abrasion resistance. They are not for use outdoors.
Buna-N grommets withstand a wider range of temperatures than other grommets and resist abrasion, oil, and grease. They are not for use outdoors.
Grommets that meet MIL-G-3036 resist hot petroleum-based oil and coolant.
