Product Overview

At SHQN, we specialize in providing high-performance sealing solutions that withstand the most demanding conditions. Our AS568 Full Series O-Rings are specifically engineered for the Oil & Gas industry , where high pressure, extreme temperatures, and corrosive fluids are the norm. Combining high-durometer hardness with exceptional tensile strength, these seals ensure zero-leakage performance in critical oil extraction equipment.

Key Features

• Full AS568 Series Compliance: We offer the complete range of American Standard sizes, ensuring a perfect fit for all global oilfield equipment and machinery.
• High Hardness & Extrusion Resistance: Available in 90 Shore A and above. Our high-durometer compounds prevent extrusion and "nibbling" under extreme high-pressure (HPHT) environments.
• Superior Mechanical Strength: Formulated for high tear resistance and durability, our O-rings maintain structural integrity even under constant mechanical stress and abrasive conditions.
• Custom Color Coding: Beyond standard black, we provide Vibrant Colored O-Rings (Green, Blue, Red, Brown, etc.). This allows for easy identification of material types or sizes during assembly, reducing installation errors on-site.
• Material Excellence: Optimized for the oilfield, our materials (including HNBR, FKM/Viton, and specialized NBR) offer excellent resistance to H2S, CO2, and aggressive drilling muds.

Applications

Our high-strength O-rings are the preferred choice for:

• Downhole drilling tools and motors.
• Blowout Preventers (BOPs).
• Wellhead and Christmas tree components.
• Hydraulic fracturing equipment.
• Subsea valves and connectors.
