About This Item

OEM Diffuser for Max-E-Glas and Dura-Glas Series Pumps

The Pentair Diffuser (C1-216P) is the OEM replacement diffuser for Max-E-Glas and Dura-Glas Series inground pool and spa pumps, sized for 1/2 HP Full-Rated and 3/4 HP Up-Rated configurations.

The diffuser channels water flow from the impeller into the pump's volute, maintaining hydraulic efficiency and proper pressure output. A cracked, worn, or damaged diffuser reduces flow performance and can cause the pump to lose prime — replacing it with the correct OEM part restores the pump to its designed operating condition.

Specifications

Pentair Part Number C1-216P
HP Rating 1/2 HP Full-Rated / 3/4 HP Up-Rated
Compatible Equipment Max-E-Glas / Dura-Glas Series Inground Pool and Spa Pumps
Quantity Included 1

Pro Tip

When replacing the diffuser, inspect the impeller and shaft seal at the same time — these components wear together and are accessible once the pump is disassembled to this depth. Replacing worn components together avoids a repeat teardown shortly after. Verify your pump's HP rating and model designation against the part number stamped on the original diffuser before ordering.

For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
