The KG and KGMS Style Grommets are designed to protect wiring and other objects that pass through a hole. These grommets will prevent chafing and cutting from the sharp edges in a panels through hole. They also effectively isolate vibrations and can even be used as spacers. KG (Industrial grade) and KGMS (Military-Spec. MS35489) Grommets will snap into a pre-drilled hole, and when sized correctly they will insulate and seal. Karman Rubber offers the KG and KGMS Style Grommets in Natural Rubber Neoprene and Nitrile (Buna-N) Compounds.
