50303190 Kit, Seal for Jungheinrich ECC 10 AC, ECD 320

Overview

The 50303190 Kit, Seal is a replacement seal kit specified for Jungheinrich electric warehouse and counterbalance trucks, including the ECC 10 AC, ECD 320 and ECE 20 HP. Seal kits handle a small but critical job: the O-rings, seals and gaskets inside restore the sealing surfaces that harden, crack and wear out after years of daily operation. If your Jungheinrich truck is losing hydraulic fluid or showing signs of a leak, fitting a fresh 50303190 Kit, Seal is a practical way to restore performance without replacing an entire cylinder or valve assembly.

Compatibility

The 50303190 for ECC and related Jungheinrich models is listed for the following trucks:

• ECC 10 AC
• ECD 320
• ECE 20 HP

Because Jungheinrich fits components across model variants and serial ranges, confirm the fit before ordering: check the number on your existing seal kit or verify against your truck’s data plate and parts manual. If you are not sure whether the 50303190 is right for your machine, send us the model and serial number and our parts specialists will confirm the application for you.

Quality and Reliability

A worn seal is one of the most common causes of hydraulic faults on warehouse trucks, so the material quality matters. The seals in this kit are elastomer compounds selected for contact with hydraulic oil and for the temperature swings, moisture and continuous duty cycles typical of busy material handling operations. Replacing the complete set of seals in one service—rather than swapping a single damaged seal—ensures even wear across the assembly and greatly reduces the chance of a repeat leak shortly after the repair. Keeping the 50303190 Kit, Seal on hand for planned maintenance helps keep your Jungheinrich trucks working instead of waiting in the workshop.

Installation and Maintenance Tips

• Depressurize and isolate the hydraulic circuit before opening any cylinder, pump or valve.
• Clean the housing, bore and seal grooves thoroughly; trapped debris can score a new seal immediately.
• Inspect the piston, rod and sealing faces for scoring or corrosion, and rework or replace them as needed.
• Fit each seal square and untwisted, using a proper fitting tool instead of a screwdriver.
• Lubricate the new seals with clean hydraulic fluid before assembly.
• After reassembly, cycle the function slowly and inspect for leaks before returning the truck to service.

Always follow the Jungheinrich service manual for your model, and replace seals as a complete kit whenever the 50303190 is specified.
