Jandy R0480300 Pro Series Backplate O-Ring

What This Part Is Used For
The Jandy R0480300 backplate O-ring is a sealing component used in compatible Jandy Pro Series heater assemblies. It helps maintain a watertight seal at the backplate connection point during normal heater operation.

Why This Part Matters
A flattened or damaged O-ring can create slow leaks that corrode internal components and damage surrounding equipment pad surfaces. Even minor seepage can lead to repeated service calls if the seal is not replaced during repairs. Installing the correct O-ring helps restore proper sealing and protects the heater from water intrusion.
