Description

The Pentair C3-186 seal plate insert is designed to provide a proper seating surface for the mechanical shaft seal in compatible pool pumps. It ensures correct alignment and sealing performance.

Made from durable copper, it resists wear and heat generated during pump operation. It is commonly used in Dura-Glas II and Max-E-Glas II pump systems.

Replacing a worn insert helps restore proper sealing and protects the motor from water intrusion.
