3.1mm cross section O-rings are engineered for the most demanding industrial applications where standard O-rings would fail. The extra thickness provides maximum extrusion resistance, making them ideal for hydraulic systems operating above 3000 psi, heavy industrial presses, mining equipment, and applications with extreme pressure spikes. The additional material also offers extended service life in abrasive environments and provides a safety margin for system surges and pressure variations.

Our 3.1mm NBR O-rings with 70A hardness are rated for extreme pressure applications, typically handling pressures up to 5000 psi (345 bar) or higher with proper groove design. The thick cross section provides exceptional extrusion resistance, making them suitable for the most demanding hydraulic systems, industrial presses, and heavy equipment. For specific ultra-high pressure applications, consult our engineering team for custom recommendations and gland design specifications.

3.1mm O-rings require precise groove design for optimal performance. Recommended groove width is 3.7-4.5mm with adequate clearance gaps to prevent extrusion. Surface finish should be 16-32 RMS, and all sharp edges must be properly chamfered. For dynamic applications, consider including backup rings. We provide detailed engineering specifications and can review your specific gland design to ensure optimal sealing performance in extreme pressure applications.

Yes, these 3.1mm NBR O-rings are specifically designed for continuous high-pressure operation in industrial environments. The NBR compound maintains its mechanical properties and sealing capability under sustained pressure, while the 3.1mm cross section provides the necessary extrusion resistance for long-term reliability. For applications involving continuous operation above 100°C or extreme pressure cycling, we recommend periodic inspection and may suggest our specialized high-temperature compounds.
