Looking to restore proper brine draw on a Fleck control valve? The FL14801-04C is the Fleck #4C Green Injector Nozzle, a color-coded metering part used in Fleck valves such as the 9500. Together with its matching throat, the nozzle forms the venturi that pulls brine solution into the mineral tank during regeneration, recharging the ion-exchange resin so it can continue removing hardness from your water supply.

• Authentic Pentair Fleck #4C Green injector nozzle
• Green color code indicates its specific draw-rate sizing
• Fits Fleck 9500 series control valves
• Available within service kit FL60157-04
• Compact precision part, roughly 0.01 lb each
• Designed to pair with the corresponding #4C throat

This individual nozzle is discontinued as a loose item and is now supplied in the FL60157-04 service kit. Buying the kit is the practical choice because the injector nozzle and throat share a single venturi pathway and tend to wear or foul together, so replacing them as a matched set yields the most reliable and longest-lasting result. Mixing a fresh nozzle with a worn throat, or vice versa, can leave brine draw weaker than intended.

Fleck injectors are tuned by color to match the resin-tank size, which determines how fast brine is drawn during the salt cycle. An undersized, clogged, or worn nozzle can starve the bed of brine and let hard water slip through to fixtures and appliances. Because the tiny orifice readily collects iron, sediment, and salt buildup, brine suction can fade gradually until softening performance noticeably declines. Periodically refreshing the injector assembly is one of the most effective maintenance steps for keeping a Fleck softener regenerating thoroughly. Installing this genuine #4C green nozzle, ideally with a clean throat, returns the valve to full venturi performance and dependable, efficient operation.

Carrying the FL60157-04 kit makes injector service a quick, planned job rather than an emergency. Because brine-draw faults develop gradually, scheduling injector replacement during routine maintenance keeps a 9500-equipped softener ahead of any decline in performance. For homeowners who notice spotting on glassware or a chalky film returning to fixtures, a tired injector is an easy and affordable first thing to address before assuming a larger problem with the resin or the valve itself.
