Benefits & What Makes It Different
Direct OEM Fit
Matches factory threads on Pentair IntelliChlor IC20, IC40, and IC60 cells perfectly, preventing cross-threading damage to expensive cell housings.
Complete 2-Pack Assembly
Includes two union nuts, two slip tailpieces, and two fresh O-rings to refresh both the inlet and outlet sides of your salt cell plumb line.
UV-Resistant Polymer
Molded from heavy-duty engineered composite to resist degradation, stress cracking, and high operating pressures under direct sun exposure.
Compatibility
- Pentair IntelliChlor IC15, IC20, IC40, and IC60 salt cells
- Pentair EasyTouch PS4/PSL4 systems with IntelliChlor integration
- Standard 2-inch PVC plumbing runs
When To Use This
Pro Tip
Hand-tighten union collars only. Using channel locks or strap wrenches on plastic cell unions frequently ovalizes the collar or fractures the threads, causing persistent leaks.
Common Questions & Instructions
What equipment does the Pentair 520595 union set fit?
This set is designed for Pentair IntelliChlor salt chlorine generator cells, including models IC15, IC20, IC40, and IC60, as well as EasyTouch systems configured with integrated IntelliChlor plumbing.
What signs indicate my IntelliChlor cell unions need replacement?
Replace these unions if you notice persistent dripping around the cell collars, visible hairline cracks in the union nut from overtightening, or worn O-rings that fail to hold pressure.
Can I install the Pentair 520595 union set myself?
Yes, installation is DIY-friendly. If you are replacing only the nuts and O-rings on existing plumbing, it takes minutes by hand. If gluing new tailpieces onto PVC, use standard PVC primer and medium-bodied cement.
