Product Overview
The Jandy R0480300 Backplate O-Ring is a critical maintenance item for maintaining the hydraulic integrity of Jandy’s Pro Series FloPro pumps. Over time, exposure to pool chemicals, UV, thermal cycling and mechanical stress can degrade the original O-ring, resulting in water leaks, inefficient pump operation or reduced system reliability. By replacing the old seal with the R0480300 O-Ring, you restore the proper factory-specified sealing surface and help ensure that the pump continues to operate leak-free.

Installation is straightforward: remove the backplate, clean and inspect the sealing surface, lubricate the new O-ring if required, and reinstall the backplate per manufacturer torque specifications. Regular replacement of this seal during pump rebuilds or maintenance can help extend pump lifespan and reduce unplanned downtime. This part is ideal for pool service professionals and OEM channels to stock as part of pump rebuild kits.
