Description

The Pentair Triton II TR 40 is built for reliability and longevity. Its fiberglass-reinforced, one-piece tank construction resists corrosion and preserves structural integrity under heat and UV exposure. Internally, the design ensures that water flows evenly through the media, which reduces pressure imbalances and maintains clean filtration over time. The GlasLok™ process bonds fiberglass tightly into the shell, preventing fiber degradation. With its durable, heavy-duty closure and threaded bulkhead ports, this unit handles heavy use and maintenance without compromising system integrity.

Pro Tip

Match this filter with a compatible multiport valve (e.g.  Pentair 261055) and always include a threaded union in your plumbing. Leave some slack in pipe runs to allow for thermal expansion.
