Product Description

Brass B-Series Injector

The B-injector works to inject fluids or air into lines conveying liquid under pressure. As water gets pushed through the injector, it creates a vacuum that induces the chemical or air into the water stream! 

B-series injectors have a Ryton metering knob, check valve core for high chemical resistance, and an external bypass screw to control water flow across the injector. This gives users flexibility during installation if water flow is unknown. Chemical dilution is determined by the metering screw or metering tip - to find the product you need, add the suffix T to the part number. 

Size: 3/8" NPT

  • Low pressure loss (35% across injector)
  • Metering knobs for various chemicals
  • Maximum Induction: 16 oz/min
