This O-ring seal is used in all sorts of lawn and garden equipment as a seal for the oil dipstick. It helps seal the system from debris and dirt that could otherwise reach the oil and end up in the motor. Over time, an O-ring will start to shrink, which can result in air and oil leaks and a poorly performing engine. If the O-ring has pits, blisters, or pocks on the surface, it will also need to be replaced.If an O-ring seal is worn, damaged, or clogged, it should be cleaned or replaced before the equipment that houses it is used again. A flat head screwdriver can be used to remove the damaged O-ring. Once the old one has been removed, a new one can be placed into the same position before using the tool.This O-ring seal is designed for lawnmowers, snowblowers, tillers, wood chippers, pressure washers, generators, and leaf blowers. It is compatible with equipment from Simplicity, Briggs & Stratton, MTD, Craftsman, Snapper, Toro, Lawn-Boy, and Cub Cadet. The seal is a genuine OEM replacement part directly sourced from the manufacturer. It comes with a single seal.
