Know before you buy
This kit includes two genuine Pentair seals, which is the standard amount needed to service a single 2.5-inch union connection.
The 410016Z kit is designed specifically for the Pentair WhisperFlo XF, IntelliFloXF, and Sta-Rite Max-E-Pro XF pump series.
No, these seals are specifically engineered for 2.5-inch union connections. They will not provide a proper fit or watertight seal on 2-inch plumbing.
Genuine Pentair parts are manufactured to the exact specifications of your pump, ensuring a precise fit and reliable performance that prevents leaks and protects your equipment's longevity.
If you notice water dripping or spraying from the union connection points on your pump, it is a clear sign that the existing seals have worn out or become brittle and require replacement.
