EC87x12 Nitrile Rubber End Cap Seal 87mm Outside Diameter 12mm Width

Nitrile Rubber End Cap Seal: The main purpose of a End Cap seal is to cap off where the shaft does not pass through the housing wall. A steel body covered with nitrile rubber provides an easy to install cap for blank holes left from the manufacturing process or where the shaft does not protrude. End cap seals are often referred to as VK seals
Benefits: Inexpensive, does not increase the width of the installation as an end cap would.
