Dosatron INJECTION SEAL KIT FOR D14MZ520 VISCOUS VF SEALS >sn13400000 -HV

Efficient Dosing for Heavy Viscous Concentrates The Dosatron D14MZ520 Injection Seal Kit is a critical maintenance solution for high-performance hydroponic systems requiring the delivery of thick, heavy additives. Unlike standard kits, this "V" designated assembly features a specialized spring-loaded check valve with a heavier spring and modified cone designed to draw viscous solutions more efficiently. This ensures that even your most dense nutrient formulations are injected with the exact precision required for a 1:500 ratio. Superior Chemical Resistance and OEM Reliability Constructed with premium Viton (VF) materials, this Dosatron maintenance kit provides exceptional resistance against the corrosive nature of commercial fertilizers and pH adjusters. It is purpose-built for D14MZ520 units manufactured after 2013, specifically fitting serial numbers 13400000 and above. By replacing your seals with this comprehensive kit—including the plunger seal and injection stem O-rings—you eliminate the risk of suction loss and maintain the airtight integrity of your pressurized irrigation line. Key features: Viscous Fluid Optimization: Features a heavy-duty spring-loaded check valve specifically designed to pull thick oils and heavy concentrates without failure.
