This is a high-quality manufacturer-sourced part which is made for use with Briggs and Stratton engines commonly installed on lawn and garden equipment. It helps to distribute the pressure evenly and provide a tight seal for the breather. Over time it may become brittle and begin to crack eventually requiring a replacement. For the proper application please refer to the appropriate diagrams of your model. This high-quality part is made of durable composite material and is sold individually. You will need a screwdriver and a wrench set to remove and reattach the breather.
