What Does the NUTRING Attachment Do? The Right Approach to Hydraulic Cylinder Maintenance

Why is felt replacement a delicate procedure?

Seal replacement in hydraulic cylinders directly affects the tightness and performance of the system. An incorrect operation can cause oil leaks, pressure loss and re-failure in a short time.

Therefore, not only the quality of the seal, but also the equipment used plays a critical role in the maintenance process.

What actually is the equipment known as a "felt attachment apparatus"?

The equipment, which is called a "seal attachment" in the field, is most often a special wrench for unscrewing and installing the front cover (gland nut) of the hydraulic cylinder.

Without this equipment:

  • It becomes difficult to open the cylinder head in a controlled manner
  • Increased risk of damage to internal parts
  • The installation of new seals cannot be done properly

In other words, the right equipment is actually the first and most critical step of seal replacement.

Why are standard hand tools not enough?

One of the most common mistakes made in practice is trying to open a cylinder with a pipe wrench or similar equipment.

This approach often leads to:

  • Marks and deformation on the cover
  • Application of unbalanced force
  • Damage to felt housings
  • Leak again

In short, although it may seem like a solution in the short term, it increases the cost in the long run.

What does the right equipment provide?

When using a professional seal attachment (gland removal wrench):

  • The lid opens and closes in a controlled manner
  • No damage to internal components
  • Seals are mounted in the correct position
  • Processing time is significantly shortened

Especially in field services, this difference directly returns as efficiency.

In which cases may it not be enough?

Not all equipment is suitable for every job. For larger rollers requiring higher torque:

  • Standard adjustable wrenches can be forced
  • Risk of slipping or breakage may occur

For such applications, stronger, heavy-duty solutions should be preferred.

Hidroman approach: Right equipment, right result

As Hidroman, one of the most common problems we encounter in the field is recurrent failures due to incorrect equipment selection.

Our approach is clear:

  • Use equipment that is appropriate for the size of the job
  • Escape uncontrolled force
  • Standardize assembly quality

This means:Longer lasting seal performanceFewer relapsesSafer maintenance process

Although the "seal attachment" may seem like a simple piece of equipment, it constitutes one of the most critical steps in hydraulic cylinder maintenance.

Maintenance with the right equipment does not only solve the problem at that moment; it also maintains the long-term performance of the system.

As Hidroman, our aim is to provide reliable and sustainable solutions that really work in the field.
