Genuine OEM Replacement Collets for EZ-FLO Proportioning Caps
The EZ-FLO Quick Connect Collet is the official replacement collet for EZ-FLO proportioning caps that use the CAP-MBT connection. These small but critical components are the quick-connect locking inserts built into the cap of your EZ-FLO fertilizer injector that grip and seal the 1/4″ tubing in place. When a collet becomes worn, cracked, or lost, the tubing connection can leak or fail to lock securely — replacing them restores a reliable, drip-free connection without the need to replace the entire cap assembly.
Each pack includes both green and blue collets — the two color-coded sizes used across EZ-FLO cap assemblies. The 6-pack (SKU: IEZQCC-6) includes 3 green and 3 blue collets, while the 2-pack includes 1 green and 1 blue collet. Keep a set on hand so routine maintenance never interrupts your fertigation schedule.
Collets are the internal quick-connect gripping rings inside your EZ-FLO cap that lock 1/4″ tubing in place under pressure. Over time — especially with repeated disconnection and reconnection — the plastic teeth can wear down, crack, or lose their grip, causing:
- Leaking at the cap connection: A worn collet no longer creates a watertight seal around the tubing.
- Tubing pulling out under pressure: Damaged collet teeth can no longer hold the tubing securely when the system is pressurized.
- Uneven fertigation: Any leak at the cap disrupts the proportional feed rate of your injector.
Replacing the collets is a quick fix that restores your injector cap to like-new performance at a fraction of the cost of a full cap replacement.
