The Custom Molded Products (CMP) Hi-Temp Long Union is an essential plumbing component for making durable, high-temperature connections in pool and spa systems. This union (MPN: 21063-154-000) is particularly useful for connecting equipment like pumps, filters, or heaters, as its union design allows for easy connection and disconnection of pipes without cutting.
Constructed from robust CPVC material, it is specifically engineered to withstand elevated heat and chemical exposure prevalent in demanding pool environments. The innovative self-sealing T-gasket design provides a superior seal, which means no messy Teflon tape or pipe dope is needed for installation.

Warnings and Disclaimers
- Professional Installation: Ensure proper installation to prevent leaks. Use appropriate [PVC Cement and Primer](https://www.oatey.com) designed for plumbing applications.
- Pressure Limits: Do not use this union in systems that exceed standard residential pool/spa operating pressures (typically <30 PSI).
- O-Ring Maintenance: Ensure the internal O-ring is properly seated and clean before tightening the union nut to create a leak-proof seal. Apply a thin layer of pool-safe lubricant seasonally.
- Cross-Threading: Avoid cross-threading the union nut during assembly, which can permanently damage the threads and cause leaks.
Pro Tips
- Maintenance Ease: This union is essential for connecting equipment like pumps or heaters, making future maintenance or replacement a simple task of unscrewing the nut rather than cutting pipe.
- High Temp Use: The hi-temp rating makes it suitable for connections near pool heaters where heat is a factor.
- Gasket Check: Always verify the rubber O-ring gasket is included and in good condition before final assembly to ensure a watertight seal.
