Product Overview

The Swimables SW‑30‑315 High Temp Union is designed for use in high-performance pool and spa plumbing where elevated temperatures and service access are key concerns. This union includes a 1.5″ male iron pipe (MIP) threaded end for connecting to pumps or heaters, and a long-neck 1.5″ socket end for gluing into standard Schedule 40 PVC plumbing.

Its long-neck socket design provides additional space between fittings, making it ideal for configurations where compact equipment or multiple connections are present. This added length also simplifies installation and provides more surface area for a secure solvent weld.

Constructed from high-temperature PVC, the SW‑30‑315 is capable of withstanding thermal stress near heaters or dry-run pumps, and resists degradation from pool chemicals over time. The integrated union nut allows for fast disassembly without tools, streamlining repairs and seasonal maintenance.

Whether used in residential or commercial systems, this union provides a reliable and cost-effective solution for connecting threaded components to PVC plumbing while maintaining a leak-free seal under high-stress conditions.
