SKY Hydraulic U-shaped Dust Seal Ring | Superior Contamination Protection & Longevity

Engineered to shield your hydraulic cylinders from abrasive contaminants, reduce downtime, and extend component life. The first line of defense for your critical machinery.

SKY Hydraulic U-shaped Dust Seal Ring SKY Hydraulic U-shaped Dust Seal Ring side view
Product Overview: The Ultimate Defense for Your Cylinders

The SKY Hydraulic U-shaped Dust Seal Ring is a precision-engineered component designed as the primary sealing element in hydraulic and pneumatic cylinders. Its robust U-cup design acts as a formidable barrier against dirt, dust, moisture, and other abrasive particles that cause internal damage, wear, and fluid contamination.

By effectively excluding contaminants, it protects the more sensitive main piston seals and rod seals, significantly extending the service life of your entire hydraulic system and maintaining optimal performance.

Key Features & Unmatched Benefits
  • Advanced Lip Geometry: Our proprietary U-shaped profile ensures a wiping and scraping action that actively removes debris during rod retraction, preventing ingress.
  • Abrasion-Resistant Material (Sakagami RN906): Manufactured from high-grade, fortified Sakagami RN906, offering exceptional tear strength and outstanding wear resistance, even in the harshest environments (e.g., mining, agriculture, construction).
  • Excellent Compatibility: Performs reliably with a wide range of hydraulic fluids (mineral-based, synthetic, HFA/HFB), water-glycol mixtures, and lubricants.
  • Easy Installation & Replacement: The simple, one-piece U-cup design allows for quick and tool-free installation, minimizing maintenance time and costs.
  • Temperature Resilience: Maintains sealing integrity and elasticity across a broad operating temperature range.
