Dust Caps

Dust caps for the tail gate – Protection for maximum service life

In daily operation, the hydraulics of a tail gate are exposed to varying temperatures, dirt, moisture and road salt, all of which attack piston rods, seals and guides. Without suitable protection, leaks, corrosion or increased wear can occur quickly. Dust caps provide essential protection – They shield the hydraulic cylinders and prevent dirt or moisture from entering the system. This ensures that cylinder movement remains precise and that the entire truck lift gate operates reliably in the long term. In this category, you will find dust caps and suitable tail gate spare parts developed specifically for professional use. SULEJ Ladebordwand stands for certified quality, precise manufacturing and maximum protection in everyday operation.

Material and designs – Dust caps for heavy-duty truck lift gate use

A dust cap is far more than a simple rubber component. Depending on the application, it is made from specialised elastomers such as NBR or EPDM. These materials are resistant to oils, grease, UV radiation and strong temperature fluctuations – Ideal for continuous use on the tail gate or lift gate. Dust caps are generally round and fixed with robust clamping bands to ensure a secure fit on the hydraulic cylinder. Only a precisely fitting dust cap provides complete protection from dirt, moisture and road salt and maintains smooth hydraulic operation over many duty cycles. Selecting the correct model is therefore essential for the safety and service life of the entire lift gate.

Care and inspection – Small routine, major protection

Despite their robust construction, dust caps are subject to natural wear. Visual inspections for cracks, holes or brittle areas should therefore be part of every regular maintenance routine. After the winter season, a detailed inspection is especially worthwhile, as road salt can attack the material and make it brittle. For cleaning, clear water or a mild soap solution is usually sufficient. Replacing a dust cap in good time reliably protects the hydraulic cylinders from corrosion and leaks and reduces maintenance and repair costs in the long term.

Quality and precision fit – The foundation for long service life

Not every dust cap provides reliable protection. Low-quality versions age faster, lose their shape or tear under stress – With consequences such as leaks and corrosion damage on the piston rods. High-quality dust caps are characterised by precise manufacturing, durable materials and accurate fit. SULEJ Ladebordwand relies on certified quality and proven components that sustainably ensure the reliability and service life of your truck lift gate.

Advantages of dust caps in practice – Small components, major effect

• Reliable protection of hydraulic cylinders from dirt, moisture and corrosion
• Reduced wear and longer service life of sealing systems
• Lower maintenance effort and reduced repair costs
• Consistent hydraulic pressure for maximum operational safety
• Sustainable value retention of the entire tail lift

In the SULEJ Ladebordwand product range, you will find dust caps that meet these exact requirements – Precisely manufactured, durable in operation and optimally matched to the hydraulic systems of modern tail gates. This ensures long-term operational reliability and availability.

Frequently asked questions about dust caps on the tail gate and truck lift gate (FAQ)

How can I tell that a dust cap needs to be replaced?

Visible cracks, holes, brittle areas or material fatigue are clear indicators. If the dust cap loses its shape or is no longer flexible, it should be replaced.

Can I replace a dust cap myself?

Yes. Replacement is generally straightforward if basic technical understanding and the correct tools are available. Clean installation is essential to avoid damaging sealing surfaces.

Which dust cap do I need for my truck lift gate?

The correct model depends on the manufacturer, type and year. The decisive factors are the dimensions of the piston rod and cylinder as well as the required length in retracted and extended condition.

Why are dust caps made from different materials?

The choice of material depends on the operating conditions – Such as oil resistance, temperature range or UV exposure. Only a material matched to the specific application ensures optimal durability.

How do different environmental conditions affect service life?

Factors such as weather, dirt and road salt can heavily affect the material. In winter, moisture and salt are particularly aggressive, while UV radiation in summer leads to ageing. High-quality dust caps are designed to withstand these stresses and protect the hydraulics throughout the year.
