This is an authentic OEM part that has been sourced directly from DeVilbiss. O-rings might seem like a very basic part of your pressure washer. O-rings are used to seal all of the connection points and parts within your machine; this ensures connections are all air tight. This o-ring is used in the chemical injector assembly, it is one of the o-rings that works to ensure there is a vacuum seal in order to help the injector siphon the chemicals. Due to the fact o-rings are made of rubber over time they will begin to wear down and become less effective.
