This Carjo kit bundles the common wear parts—shaft O-ring, volute O-ring, and two R0445500 (PS-4231) pump shaft seals—so you can complete a reliable rebuild without sourcing multiple components. The parts are selected to match fit and function for PB4-60 3\/4 hp models from 2012 to present and come with straightforward installation guidance to streamline maintenance.\u003c\/p\u003e\n\n\u003ch3\u003eWhat exactly is included in the seal kit?\u003c\/h3\u003e\n\n\u003cp\u003eThe kit includes all the essential sealing components needed for a standard Polaris PB4-60 booster pump rebuild. You get a shaft O-ring and a volute O-ring plus two identical pump shaft seals (R0445500 PS-4231) so both sides of the rotating assembly are sealed properly. Each component is manufactured for durability and dimensional accuracy to help restore the pump’s water-tight integrity.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eShaft O-ring sized for PB4-60 rotating assembly\u003c\/li\u003e\n  \u003cli\u003eVolute O-ring to seal the pump housing\u003c\/li\u003e\n  \u003cli\u003eTwo R0445500 (PS-4231) pump shaft seals for both seal faces\u003c\/li\u003e\n  \u003cli\u003eBasic installation guidance to assist with replacement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does this kit improve pump performance?\u003c\/h3\u003e\n\n\u003cp\u003eReplacing aged or damaged seals reduces leaks, cavitation risk, and pressure loss, which helps the pump maintain designed flow and pressure. Fresh seals restore the hydraulic seal between the wet end and the motor, minimizing water intrusion into the motor and reducing wear on internal components. The result is steadier operation, fewer interruptions, and a longer service life for the booster pump.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eStops shaft and housing leaks that lower efficiency\u003c\/li\u003e\n  \u003cli\u003eReduces water contact with motor bearings and windings\u003c\/li\u003e\n  \u003cli\u003eHelps maintain factory flow and pressure specifications\u003c\/li\u003e\n  \u003cli\u003ePrevents premature component wear caused by leaks\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIs the Carjo kit easy to install for a DIYer?\u003c\/h3\u003e\n\n\u003cp\u003eYes — the kit is designed with DIY-friendly parts and clear, simple steps so a competent homeowner or pool technician can complete the repair.
