The FL17224 is a genuine Fleck O-ring, AS568 dash size -224, from Pentair. This elastomer seal fits a specific internal joint within a Fleck control valve, compressing between mating surfaces to create a watertight barrier that prevents leaks and internal bypass under operating pressure. The standardized -224 dash size identifies its exact dimensions, ensuring a precise, repeatable fit.

This individual O-ring has been discontinued but remains available in several service kits, including FL61956-01, FL61956-02, and FL61956-03. Those kits group the -224 seal with the other O-rings and parts commonly refreshed together during a valve rebuild, which is the recommended way to source it since seals are best replaced as a complete set.

• Genuine Fleck -224 size O-ring
• Seals an internal control-valve joint

O-rings are small and inexpensive, but they are central to a control valve's leak-free operation and proper sealing between stages. With age and use, the elastomer hardens, takes a compression set, or develops cracks as exposure to water, pressure, and any chlorine in the supply gradually breaks it down. A worn seal is one of the most common causes of weeping leaks and erratic valve behavior, and it can be easy to overlook as the root cause when chasing a drip or a performance issue.

The -224 dash size designation specifies the exact dimensions needed for a correct fit, so the seal seats properly without guesswork or improvisation. Many technicians replace the full O-ring complement whenever a valve is open, returning the system to dependable, leak-free service and avoiding a follow-up call over a single tired ring. Sourcing the -224 through one of the FL61956 kits provides a fresh, matched set of seals for a thorough rebuild.

For installers, sourcing the -224 through one of the FL61956 kits is the practical route now that the loose part is discontinued, and it conveniently supplies a fresh, matched set of seals for a complete rebuild. Renewing all the O-rings at once while the valve is open is sound practice that prevents a sequence of separate leak callbacks, returning the system to dependable, leak-free service with a single thorough job.
