The 7110303 plastic protective cover is a black plastic vent cap cover that fits over the oil breather plug on compatible AAA triplex pressure washer pumps.

The breather plug allows the pump crankcase to vent internal pressure during operation. This cover shields the breather from debris that can contaminate the pump oil and cause premature wear to internal seals and bearings.

Why Is My Pressure Washer Pump Leaking Oil or Running Rough?

If the vent cap cover is missing, cracked, or damaged, contaminants can enter the pump crankcase through the exposed breather. Over time this leads to oil contamination, accelerated seal wear, and potential pressure loss.

Replace this cover if it is visibly cracked, missing, or if debris is found in the pump oil during routine maintenance. Inspect the vent cap cover during every oil change or seasonal service.
