High-Ratio Precision with the D14MZ520 Injection Stem

The Dosatron D14MZ520 Injection Stem Upper Sleeve is a critical component for growers utilizing high-ratio nutrient injection systems. Designed exclusively for the 1:500 Dosatron model, this hydroponic injector part houses the internal plunger assembly and provides the structural foundation for your dosage adjustment settings. Its specialized side port opening is vital for maintaining the specific bypass or auxiliary injection configurations required by the MZ520 series, ensuring your facility operates at peak efficiency.

Durable Engineering for Commercial Fertigation

Constructed from high-grade, chemical-resistant polypropylene, this Dosatron replacement sleeve is built to withstand the rigors of aggressive nutrient concentrates and continuous commercial use. By replacing a worn upper sleeve PDI1159U, you prevent pressure loss and maintain the airtight seal necessary for accurate volumetric proportioning. This component serves as the primary connection point for your injection system, allowing for seamless integration and long-term reliability in demanding cultivation environments.

Key features:

• Model-Specific Fit: Engineered exclusively for the Dosatron D14MZ520 (1:500 ratio) to guarantee perfect alignment and performance.
• Integrated Side Port: Features the essential side opening required for auxiliary injection and specific bypass plumbing configurations.
• Chemical-Resistant Build: Manufactured from premium polypropylene to resist degradation from salts and concentrated liquid nutrients.
• Precision Dosing Support: Provides a secure housing for the plunger assembly, ensuring consistent 1:500 dilution accuracy.
• Rapid Maintenance: Simplifies the repair process for the injection stem, reducing downtime in commercial fertigation schedules.
