Dosatron® D25RE2 Injector Injection Stem Assembly
Product Overview
When an injection stem fails during the height of the growing season, your entire fertigation program grinds to a halt. Without precise nutrient delivery, crops suffer from deficiencies and turf quality rapidly declines, leading to costly remediation or lost yields. Peak demand periods often coincide with regional supply shortages, making it difficult to source specific Dosatron components exactly when you need them. Maintaining a stocked inventory of these critical wear parts ensures your crews can perform immediate field repairs, preventing extended system downtime and keeping your project deadlines on track during the busiest months of the year.
The Dosatron D25RE2 Injection Stem Assembly is engineered to provide superior chemical resistance compared to generic or off-brand replacement parts. By using genuine manufacturer components, you eliminate the risk of improper fitment or premature seal failure that often plagues lower-grade alternatives. This assembly streamlines the maintenance process, allowing your technicians to restore factory-spec precision in minutes rather than hours. Investing in high quality components reduces the frequency of service calls and lowers the long term cost of ownership for your clients, giving your firm a reputation for reliability in the field.

Installation Notes
Before installing the new stem assembly, ensure the injector body is depressurized and the water supply is shut off. Remove the old stem by unthreading the check valve nut and sliding the assembly out of the lower housing. We recommend lightly lubricating the O-rings with a silicone-based lubricant to ensure a watertight seal and to prevent binding during future maintenance. Always check local plumbing codes for backflow prevention requirements when integrating chemical injection into potable water supplies.
