Product Overview

The Swimables SW‑30‑320 High Temp Union is a robust, long-necked union tailored for demanding pool, spa, and heater-connected plumbing. Featuring a 2″ male iron pipe (MIP) threaded end and a 2″ long-neck socket, it bridges threaded equipment to standard Schedule 40 PVC piping with precise alignment and adequate clearance.

Its extended socket neck helps avoid tight-fit issues, simplifies solvent-weld installation, and provides reach to bypass elbows or compact equipment layouts. Made from heat-rated PVC, the union resists elevated temperatures, sanitizing chemicals, and physical stress—making it suitable for heater systems, pump dry-run protection, and other high-temperature plumbing zones.

Designed as a self-sealing union, it ensures a secure, leak-free connection without thread sealants. The union nut allows easy hand tightening and quick servicing, greatly reducing downtime during routine maintenance or equipment swaps.

Ideal for both residential and commercial installations, the SW‑30‑320 offers reliable performance, easy serviceability, and extended system life—particularly in high heat or tight-fit plumbing situations.
