Pentair 2.5" Union Kit without Tap for IntelliFloXF and IntelliProXF Variable Speed Pumps, 410020

Pentair 410020 Union Kit without Tap For WhisperFloXF(R) and IntelliFloXF(R) Variable Speed Pump

The Pentair 2.5" Union Kit without Tap (Part Number 410020) is a genuine Pentair replacement assembly designed specifically for variable speed pump systems such as the IntelliFlo® XF, IntelliPro® XF, and compatible Sta-Rite models. This kit is engineered to provide a secure, leak-free connection between your pump’s plumbing and the rest of your pool system—an essential requirement for maintaining optimal flow and energy efficiency in modern pump setups.

What's Included

The kit typically contains the following components:

• Two (2) Clip Locking Rings: These help secure the union adapters in place, ensuring the connection remains firm under pressure.

• Two (2) Union Adapters Without Tap: Designed to mate with your pump’s plumbing, these adapters establish the core of the connection. The “without tap” designation means the kit does not include an integrated valve—providing flexibility for systems where an external control tap is preferred.

• Two (2) Union Nuts: These nuts ensure that the adapters are tightened securely, which is vital for preventing leaks.

• Two (2) Diamond Seals: Used for creating a durable, leak-free seal that withstands continual use and changes in pressure.

Design and Compatibility

The union kit is versatile in its application. It’s designed to work with both 2‑1/2-inch and 3-inch plumbing:

• For 2‑1/2-inch piping: The union adapter is glued inside the pipe, ensuring a smooth, seamless connection.

• For 3-inch piping: The union is applied externally, accommodating a wider range of installation scenarios.

This dual compatibility makes the kit a flexible solution for various installation environments, whether you’re replacing an old component or setting up a new system with variable speed pumps. Its design ensures that the connection is both secure and able to maintain the performance benefits that come with modern, energy-efficient pump models2.
