From an engineering perspective, the direct conclusion is this: Pneumatic cylinder seal kits and hydraulic cylinder seals are generally not interchangeable and cannot be directly substituted for one another.

Not all instances of corrosion in cylinder seal kits require immediate replacement. If the damage consists only of: • Slight surface discoloration • No obvious deformation • Elasticity that remains good The kit may still retain some functional capacity for a short period.

The cylinder's output force comes from the pressure of compressed air. If the pneumatic cylinder seal kits are damaged, air may leak from the seals, causing the internal pressure of the cylinder to become unsustainable, thus reducing thrust.

During long-term operation, pneumatic cylinder seal kits constantly come into contact with and rub against the cylinder wall and piston surface. If lubrication is insufficient or the surface roughness is high, the wear rate of the seals will accelerate. Ultimately leading to a drop in internal cylinder pressure.

During long-term operation, the piston repeatedly moves inside the cylinder. The seals need to maintain contact with the cylinder surface to achieve a sealing function. With increased use, the sealing rings in pneumatic cylinder seal kits may gradually wear down, leading to a decrease in sealing performance.

Under normal design and installation conditions, pneumatic cylinder seal kits should be stably fixed within the sealing groove. If they detach, it usually indicates a problem in some aspect. Common causes include improper installation, an inadequate sealing groove design, material aging, and abnormal pressure.
