Product details
The SuperPro GO-KIT38-9 is a gasket and o-ring kit with the shaft seal included, built for Sta-Rite P4E and P4EA series MAX-E-GLAS II and DURA-GLAS II pumps. SuperPro lists it as Gasket and O-Ring Kit 38, and it crosses to U.S. Seal part PSK-ST3.
What you get
Six pieces: the O-113 seal plate o-ring, the O-240 seal plate housing o-ring, the AS-1521 shaft seal, the O-83 diffuser o-ring, the O-12 lid o-ring and the O-39 drain plug o-ring. That is every soft part the pump needs to come back together, including the mechanical seal that is usually ordered on its own.
Why a kit rather than one part
Pool pump o-rings harden with heat and chlorine, and the set ages together. Pulling a pump apart to change one leaking o-ring and reusing the rest often means going back in a few months later for the next one. Doing them all while the pump is open costs one teardown instead of several.
Check the pump first
Confirm you have a Sta-Rite P4E or P4EA series MAX-E-GLAS II or DURA-GLAS II. Sta-Rite used similar names across different pump bodies, and the o-ring sizes are not shared between them.
