Keep your MixRite TF5 2% Injector (IMRTF52) running at peak performance with this genuine OEM replacement seal kit (MPN: 35200000002) from DEMA Engineering. Over time, the internal seals on a MixRite injector wear with normal use — this kit contains all three seals needed for a complete service: the upper piston seal, the lower piston seal, and the suction seal.
Replace the piston seals when the injector begins to stutter or fails to operate at low flow rates. Replace the suction seal when the unit stops drawing fertilizer or does so irregularly. Keeping a spare kit on hand ensures fast, minimal-downtime maintenance for your fertigation system. This kit is compatible only with the TF5 2% model — please verify your injector model before ordering. Also available: seal kits and piston kits for other MixRite models.

When should I replace the piston seals?
Replace the piston seals when your MixRite injector starts to stutter or no longer operates reliably at low flow rates where it previously functioned normally.
When should I replace the suction seal?
Replace the suction seal when the injector stops drawing fertilizer from the supply tank, or begins to do so erratically and inconsistently.
Will this seal kit fit other MixRite models?
No. This kit is designed exclusively for the TF5 2% injector (IMRTF52). DripWorks carries separate seal kits and piston kits for other MixRite models — always verify your model number before ordering.
