About this product

Product information from the supplier.

The Standard Hydraulic DKB Type Dustproof Wiper Oil Seal is a high-performance sealing solution engineered specifically for hydraulic cylinders. By integrating a robust rubber compound with a precision-engineered metal ring, the DKB wiper effectively prevents moisture, dust, and external contaminants from penetrating the cylinder housing, thereby protecting critical internal components from premature wear.

Designed for versatility and durability, these wiper seals ensure a superior static seal within the housing, eliminating the risk of particles entering around the outside of the seal. Whether used in heavy industrial machinery or precision hydraulic systems, the DKB type provides the reliable barrier necessary to maintain system pressure and extend the operational lifespan of your equipment.

Frequently Asked Questions

Q: What makes the DKB type wiper seal different from standard rubber seals?

The DKB type incorporates a metal ring that provides superior structural support and prevents the rubber from shifting, ensuring a more consistent and tighter seal against external contaminants.

Q: Can these seals be customized for non-standard cylinder sizes?

Yes, while we provide a comprehensive size catalog, we specialize in customized manufacturing to meet specific dimensions required for unique industrial applications.

Q: Which materials are used in the manufacturing of DKB wiper seals?

We use high-grade industrial rubber optimized for elasticity and wear resistance, combined with a precision-stamped metal ring for rigidity.

Q: How does a wiper seal improve the life of a hydraulic cylinder?

By acting as the first line of defense, it prevents dust and grit from entering the cylinder, which significantly reduces scoring on the piston rod and wear on internal seals.

Q: What is the Minimum Order Quantity (MOQ) for these products?

Our standard Minimum Order Quantity is 20 pieces, allowing for flexible procurement for both small repairs and larger maintenance overhauls.

Q: Are these seals compatible with high-pressure hydraulic environments?

Yes, the DKB type is specifically designed for hydraulic cylinders, providing the necessary outside static sealing to withstand typical industrial operating pressures.
