2” Male Thread NPT High Heat Union
Product Overview
Pool techs across DFW stock this Praher union because it reliably handles the high-temperature discharge from gas heaters without warping.
This 2” Male Thread NPT High Heat Union from Praher Plastics is engineered with CPVC to withstand the elevated temperatures found at pool heater discharge points. Unlike standard PVC unions that can warp or leak under thermal stress, this specific model maintains its structural integrity up to 200°F. It provides a reliable disconnect point for equipment maintenance without requiring pipe cutting.
Benefits & What Makes It Different
CPVC High-Heat Rating
Rated for temperatures up to 200°F, preventing the common melting or deformation issues seen with standard PVC fittings near heaters.
2-Inch NPT Male Threads
Precision-molded threads ensure a secure, leak-free connection to standard 2-inch female ports on pumps and heaters.
Serviceable Union Design
Allows for quick equipment removal or replacement by simply hand-loosening the nut, saving time during winterization or repairs.
Compatibility
- Compatible with 2-inch Schedule 40 or Schedule 80 PVC pipe
- Fits 2-inch Female NPT (National Pipe Thread) ports
- Safe for use with chlorine, bromine, and saltwater systems
When To Use This
Pro Tip
Pool techs across DFW stock these because installing them on the heater outlet prevents 'plumbing creep,' where hot water causes standard pipes to sag and eventually leak at the threads.
Common Questions & Instructions
Why do I need a high heat union instead of a standard PVC union?
Standard PVC begins to soften at 140°F, whereas this CPVC union reliably handles temperatures up to 200°F, which is critical for the plumbing directly connected to a pool heater.
Will this union fit my 2-inch pool pump or heater?
Yes, if your equipment has a 2-inch female NPT port, this male-threaded union is the standard specification for creating a detachable connection.
How often should the O-ring inside the union be replaced?
In our experience, the internal EPDM O-ring should be inspected annually and typically replaced every 3 to 5 years to maintain a watertight seal.
