How quality O-Rings make a difference for pool pros?
A worn bulkhead O-ring is one of the most common causes of persistent air bubbles in the pump basket or pressure drops at the filter. Furthermore, choosing quality OEM O-Rings makes installation easier and quicker, given that generic O-rings can be unreliable and cannot fit correctly. Pro Tip: When replacing the SX360Z1, clean the sealing surfaces and apply a thin layer of silicone-based lubricant for best results.
How does the Hayward SX360Z1 compare to generic O-rings?
Always Choose OEM Hayward O-rings like the SX360Z1 match the exact dimensions, hardness, and compression characteristics required by the filter design. Specifically, generic versions often vary in tolerances and lifespan. Furthermore, the correct OEM ring seats more easily, eliminates chronic leaks, and withstands long-term chemical exposure. When you want consistent pressure and hassle-free operation, genuine Hayward parts deliver the most dependable performance. Pro Tip: If you see small bubbles in the pump basket after startup, replace the bulkhead O-ring before troubleshooting more complex issues—this simple fix resolves most minor air leaks.
