Homelite NOS Pump O-Ring 43315

This Homelite 43315 O-ring is an authentic New Old Stock pump seal used in several Homelite AP-series water pumps, including models AP520, AP2202, AP2201, AP5201, and AP3201.
These pumps rely on precisely sized OEM O-rings to maintain pressure, prevent cavitation, and keep the pump housing sealed under load.

After decades of service, original pump seals dry out or flatten, causing pressure loss and water leaks. Installing this factory-sized O-ring restores proper sealing and helps bring older Homelite pump systems back to working condition.
