King Technology 2745551 Pool Frog Cap with O-ring

Product Description

The KING TECHNOLOGY 2745551 is a replacement cap with integrated O-ring designed for Pool Frog 40K sanitizing systems. The cap provides a sealed closure for the mineral or bac pak reservoir, maintaining proper chemical containment during system operation. Pool service professionals and pool technicians install this part as a routine maintenance item when the original cap is worn, cracked, or has a compromised O-ring seal. A failed cap or degraded O-ring can allow water bypass and reduce sanitizer effectiveness, making timely replacement important for water quality maintenance.

This cap is used in residential pool applications running the Pool Frog 40K system. The 40K designation refers to the system sized for pools up to 40,000 gallons. It is typically serviced during routine pool maintenance calls or at the start and end of the swim season when sanitizer paks are replaced and components are inspected for wear.
