Official EZ-FLO Replacement Inlet Tubing for Fertilizer Injectors
The EZ-FLO 1/4″ Black Poly Tubing (5′ Roll) is the official replacement inlet tubing for EZ-FLO fertilizer injector systems. This 1/4″ black polyethylene tubing is specifically designed to transport fresh water from your mainline into the EZ-FLO tank — it connects to the blue connector nut on the EZ-FLO cap (the inlet side). Having a spare roll on hand means you can quickly restore your EZ-FLO fertilizer injector to full operation without delays during the growing season.
The black color of this tubing is intentional — it helps block light penetration, which discourages algae growth inside the line and extends the service life of the tubing. This tubing works in tandem with the EZ-FLO Clear Tubing (5′), which is the outlet tubing that carries the fertilized solution from the EZ-FLO tank back into your irrigation line (connecting to the green outlet on the EZ-FLO cap). Both tubing pieces are sold separately — make sure to pick up both if you are replacing the full tubing assembly on your injector.
Understanding which tubing goes where is essential for proper EZ-FLO setup and maintenance.
The EZ-FLO fertilizer injector uses two separate pieces of 1/4″ poly tubing to route water and fertilizer solution through the tank:
Black Tubing (This Product) — Inlet Side:
Connects the mainline water supply to the blue connector nut on the EZ-FLO cap. Water flows in through this tube, passes through the fertilizer tank, picks up the fertilizer solution, and exits via the outlet side. The opaque black material blocks sunlight to help prevent algae buildup.
Clear Tubing (Sold Separately) — Outlet Side:
Connects the green outlet on the EZ-FLO cap back into your irrigation mainline. This tube carries the fertilizer-enriched water from the tank into your drip system for distribution to your plants. The EZ-FLO Clear Tubing (5′) is available separately.
When replacing tubing, always inspect both the inlet (black) and outlet (clear) lines. If one is worn or cracked, it is good practice to replace both at the same time.
