30623 PACKING KIT CAT
If your CAT Pump pressure washer pump is leaking water, losing pressure, or you’re noticing a general performance decrease, it’s time to check your seals! Seals act like gaskets – they prevent leaks. While CAT Pump seals are built to last, it’s important to check and evaluate your pumps every 1500 operating hours.
