Chemical Injectors Banner


The heart of our Aqua-Lab Chemical Dispensing System, Chem-Flex Injectors are color-coded based on the water flow needed for each individual application, and combine with color-coded chemical metering tips to proportion the precise chemical mix ratio. Choose between Standard – SST or All-Composite injectors.



  • Chemical-Resistant – Chem-Flex injectors are one the most chemical resistant injectors on the market. These long lasting injectors are manufactured using Kynar® Venturi inserts, stainless steel connections, a Hastelloy® spring, a Teflon® check ball, and an exclusive XFC o-ring material.
  • Durable – Dual material construction combines the excellent corrosion and chemical resistance of Kynar® with the mechanical strength of stainless steel. NPT injectors now use 316 stainless steel for longer life.
  • Reliable – Because of their Kynar® molded wetted surface, Chem-Flex Standard Injectors can last 2-4 times longer than injectors machined from stainless steel or brass.



  • The Most Chemical-Resistant Injector on the Market – Hydra-Flex’s innovative composite injector stands up to the most aggressive, yet common, car wash chemicals. The nozzle and body of these injectors are manufactured using a corrosion-resistant composite material, which has been tested by the industry’s leading chemical manufacturers with consistently positive results.
