The EZ-FLO 1/4" Tubing Clamp is an official replacement and maintenance part designed specifically for EZ-FLO fertilizer injection systems. Its sole purpose is to create a secure, leak-proof connection where the 1/4" clear or black supply tubing attaches to the injection barbs on EZ-FLO installation couplers.
These clamps are required in two specific installation scenarios: when your system operates at or above 50 PSI, or when the injector is installed upstream of automated timers or valves and is therefore subject to constant water pressure. In either case, the barbed connection alone is not sufficient to hold the tubing securely — the clamp ensures the tubing stays firmly seated on the barb under pressure, preventing leaks and fertilizer bypassing the injection point.

Do I always need to use these clamps with my EZ-FLO injector?
Not always, but in two situations they are required: when your system runs at or above 50 PSI, and when your EZ-FLO injector is installed upstream of (before) your automated timer or valve, placing the coupler connections under constant water pressure.
In lower-pressure, intermittent systems where the injector is installed after the timer, the barb connection alone may hold adequately — but adding clamps is always a smart precaution to guard against long-term wear or tubing creep.
What tubing does this clamp fit?
This clamp is designed specifically for EZ-FLO's 1/4" supply tubing, available in both clear and black versions, as used on standard EZ-FLO installation couplers.
It is not a universal tubing clamp and is intended only for use with EZ-FLO 1/4" barbed coupler connections. Using it on other tubing or fittings is not recommended.
How do I install the tubing clamp?
After pushing the 1/4" supply tubing fully onto the injection barb of the EZ-FLO coupler, slide the clamp over the tubing and position it directly over the barb. Tighten the clamp snugly to lock the tubing in place.
Do not overtighten to the point of cutting into the tubing. The goal is a secure, leak-free grip — not compression that could damage the tubing wall.
