12281 Tank Base O-Ring for Fleck 5600 9000 Control Valve Water Softener

Key features

• Replaces Part Number 12281 O Ring with Silicone Grease – This set includes two 12281 o-rings and a small amount of silicone grease for easier installation. Designed as a direct replacement for the tank body o-ring used in Fleck 5600 and 9000 water softeners. Also compatible with other systems requiring a 12281 tank base o-ring
• Restores Seal Between Valve and Tank Body – When the original tank body o-ring replacement is overdue, water can leak where the control valve connects to the tank. Installing this water softener o ring seal kit helps re-establish a proper seal, reducing leaks and pressure loss. Works as a filter tank body o ring to keep the connection tight
• Exact Dimensions for Proper Fit – Each 12281 o-ring measures approximately 3.100 inches inside diameter, 3.520 inches outside diameter, and 0.215 inches thick. These dimensions match specifications, ensuring a secure fit without forcing or stretching the ring
• Durable Material for Water Softener Use – Made from flexible rubber that holds its shape under normal operating conditions. This water softer o-ring resists compression over time, helping maintain a consistent seal between the tank body and control valve. The included silicone grease helps the o-ring seat smoothly
• 2-Pack for Maintenance Convenience – Each order includes two o-rings (also called gaskets or seals). Use one for immediate repair and keep the second as a spare for future water softener maintenance. Compatible with Fleck 5600 brine injector o-rings applications and similar tank connection points
