Precision DKBI Dust Sealing Component for Hydraulic Systems
Secure Axial Groove Installation Design with Stable Metal Shell Support
The DKBI dust seal is a high-performance protective component tailored for hydraulic systems, designed to block dust, dirt, and metal chips—key to preventing internal cylinder wear and damage. It adopts a double-lip structure made of polyurethane (PU) for strong sealing, plus a metal shell that provides stable support and enables secure axial groove installation. With excellent wear, oil, and aging resistance, it performs reliably in harsh environments, perfect for construction machinery (excavators, forklifts) and hydraulic pumps. By safeguarding hydraulic parts, it reduces maintenance frequency, lowers costs, and extends the overall service life of hydraulic systems, delivering consistent value for industrial applications.

1. Product Advantages
Crafted by Forever Seals, the DKBI dust seal stands out with exceptional durability and sealing performance. Its double-lip polyurethane (PU) structure delivers strong dust-blocking capability, while the integrated metal shell enhances structural stability and resistance to external mechanical impact. With excellent wear, oil, and aging resistance, it maintains reliable performance even in long-term use, reducing frequent replacement costs for users.
2. Working Principle
The DKBI dust seal operates through its precision-engineered double-lip design. Installed in the axial groove of hydraulic cylinders, the PU lips closely fit the cylinder surface to form a tight barrier, effectively blocking dust, dirt, and metal chips from entering the internal system. The metal shell ensures the seal stays securely in place, preventing displacement during equipment operation and sustaining consistent sealing efficiency.
3. Product Details
Material: High-quality PU for the sealing lip (wear-resistant, oil-resistant) and sturdy metal for the outer shell (anti-deformation).
Design: Double-lip structure for enhanced dust resistance; compact size to fit most hydraulic system installations.
Installation: Designed for easy and secure axial groove mounting, no complex tools required, saving installation time.
4. Application Range
Ideal for hydraulic systems in various industrial fields, including construction machinery (excavators, forklifts), automotive manufacturing, and heavy-duty equipment. It is also suitable for hydraulic pumps, vacuum pumps, and other components that require effective dust protection to avoid internal part wear.
5. FAQ
Q: How long does the DKBI dust seal last?
A: Under normal working conditions, it can serve for 1-2 years (varies by usage environment); Forever Seals recommends regular inspection for optimal performance.
Q: Is it compatible with all hydraulic oils?
A: Yes, its PU material is compatible with most industrial hydraulic oils, ensuring no chemical reactions or performance degradation.
