About This Item

The Pentair 2" / 2.5" Union Kit (410028Z) is the OEM replacement union kit for the IntelliFlo3 and IntelliPro3 Variable Speed and Flow 3.0 HP pool pumps, supplying the slip union connections at the pump's suction and discharge ports.

IMPORTANT: KIT INCLUDES MULTIPLE COMPONENTS
This listing is for a kit containing both the 2" and 2-1/2" union assemblies. One kit is required per pump installation. Confirm your pump's port sizing before ordering.

Union connections allow the pump to be disconnected from the plumbing system without cutting pipe — essential for motor service, winterization, or pump removal. This kit supplies the union bodies and tailpieces sized and rated specifically for the IntelliFlo3 and IntelliPro3 3.0 HP platforms. Verify the part number 410028Z against the label on your pump or the markings on your existing union bodies before ordering — this kit is specified for 3.0 HP models only.

Poolaroo Pro Tip

When replacing pump unions, inspect the union O-rings at the same time. Worn or flattened O-rings are a leading cause of drips at union joints after reassembly — replacing them during the same service visit adds minimal cost and prevents a return trip. Lubricate any O-rings with a silicone-based lubricant before reinstalling. This kit is specified for IntelliFlo3 and IntelliPro3 3.0 HP models — if your pump carries a different horsepower rating, verify the correct union kit part number in your pump's installation manual before ordering.
