Pentair 2" Slip Unions Kit
Product Overview
The standard specification for serviceability, these Pentair unions allow for equipment removal without the need for plumbing cuts.
This Pentair 2-inch slip union kit is a proven choice for plumbing IntelliFlo pumps and MasterTemp heaters where service access is a priority. Unlike generic PVC fittings, these are engineered with high-temperature tolerances to prevent warping near heater outlets or pump suctions. In our experience, using genuine Pentair unions ensures a precise O-ring seat, preventing the common air leaks found with off-brand alternatives.
Benefits & What Makes It Different
High-Temp CPVC Construction
Reliably handles the heat generated by pool heaters and high-performance pumps without softening or leaking over time.
Self-Aligning O-Ring Seal
Features a specific groove design that ensures a watertight seal even if the plumbing is slightly off-angle during installation.
Service-Friendly Design
Allows homeowners and techs to disconnect equipment for winterization or repair without cutting into the main plumbing line.
Compatibility
- Pentair IntelliFlo and WhisperFlo pumps
- Pentair MasterTemp and Max-E-Therm heaters
- Standard 2-inch PVC schedule 40 or 80 pipe
When To Use This
Pro Tip
Always hand-tighten these unions; using a pipe wrench can crack the nut or over-compress the O-ring, leading to a leak that is difficult to stop without a full replacement.
Common Questions & Instructions
Will these unions fit other pump brands besides Pentair?
While the slip side fits standard 2-inch PVC, the threaded side is specifically designed for Pentair equipment like the IntelliFlo and WhisperFlo; they may not seat correctly on other brands' proprietary threads.
Do I need to use Teflon tape or pipe dope on the union threads?
No, these unions rely on a rubber O-ring for the seal. Applying tape to the threads can actually prevent the union from tightening enough to compress the O-ring, leading to leaks.
How often should the internal O-rings be replaced?
We recommend inspecting and lubricating the O-rings annually with a silicone-based lubricant and replacing them every 3 to 5 years to prevent dry-rot and suction-side air leaks.
