Replacing the Pentair 410016Z Union Diamond Seal Kit 2.5" will help prevent cracks over time caused by heat and UV rays.
Who is this for?
If the seal on the suction side fails, the pump will draw air into the system causing visible air bubbles in the pump basket. Replace with the Pentair 410016Z Union Diamond Seal Kit 2.5" to help prevent this.

How do Pentair OEM pool products compare to Non-OEM Pentair pool products?
Pentair OEM pool products meet exact Pentair specifications. As a result, they provide reliable fit and consistent performance. Additionally, materials and quality control meet Pentair standards for offering dependable and lasting products.
Non-OEM products cost less and material quality and manufacturing precision vary. Furthermore, these generic products may not always be compatible with Pentair. Additionally, the lifespan and performance may be reduced. Overall, OEM components deliver quality, while non-OEM products, deliver uncertainty.
Pro Tip: Pentair 410016Z Union Diamond Seal Kit 2.5"
Hand-tighten the union collar snugly and avoid using channel locks or wrenches which can crack the plastic union or distort the rubber.

After researching our pool filter options, we decided to buy the Aquastar PLF35000 that our local pool guy recommended. I reached out before ordering to confirm pricing and availability. Clinton responded promptly (on a weekend) and followed up with sending an invoice that made ordering easier with just one click. Filter arrived as scheduled. From inquiry to install, all was complete within a week! Thanks for the help Clinton.
