Rolair Systems 3000PHPK30 Piston Assembly For K30 Pump

Rolair Systems 3000PHPK30 is the high‑pressure piston assembly for the K30 pump, a genuine Rolair replacement part designed for the HP stage of Rolair’s K30 two‑stage pump configuration. In official Rolair documentation this component is listed as Piston Assembly – HP, Part 6‑Part 3000PHPK30, confirming its role as the high‑pressure piston assembly for the K30 pump. It is used with Rolair K30 pump configurations, including models in the 8422HK30 family where the service literature specifies the K30 HP piston configuration. Replacing the HP piston assembly restores correct clearance and high‑pressure performance in the pump’s compression stage, helping maintain consistent output for professional air‑tool operation. When matching parts, verify that your pump requires the 3000PHPK30 designation to ensure compatibility with the K30 HP configuration.
