3921028 GASKET, COUPLING, 2-1/2” GROOVED END NBR

Specially manufactured for high-temperature oil-based muds!
2" ANSI Groove Clamp High-Temperature Oil Resistant NBR Gasket

(Nitrile Butadiene Rubber | ANSI Grooved Installation)

Key Features:​
✓ ​ANSI B16.21 Standard: Precision-engineered groove clamp design for seamless integration with ANSI flange systems
✓ ​High-Temperature Resistance: Continuous operation up to ​120°C (250°F)​​ with peak tolerance to ​150°C (302°F)​
✓ ​Superior Oil Resistance: NBR formulation resists degradation from petroleum oils, lubricants, and fuels
✓ ​Triple-Seal Technology: Pre-compressed sealing lip + groove clamp lock + radial pressure self-compensation
✓ ​Anti-Extrusion Structure: Reinforced aramid fiber core withstands pressure up to ​3,625 psi (25 MPa)​

Applications:​
► High-temperature oil transfer pipelines
► Hydraulic systems in petrochemical equipment
► Lubrication circuits for turbines/power generators
► Heavy-duty machinery pressure lubrication lines

Certifications & Performance:​
◆ 50% faster installation vs. bolted seals (tool-free clamp system)
◆ Complies with API 6A fire resistance (ISO 10423)
◆ Dynamic friction coefficient ≤0.3 for vibration-prone environments


Specifications:​
• Size:2"
• Standards: ANSI Class 150/300/600
• Material: High-acrylonitrile NBR (Nitrile Rubber)
• Temp. Range: -40°F to +250°F (-40°C to +120°C)

Engineering Notes:​
① ​Pressure-Activated Seal: V-shaped profile expands under system pressure to eliminate leakage paths
② ​Thermal Compensation: Spring-steel clamp maintains constant load during thermal cycling
③ ​Media Limitations: Not recommended for phosphate ester fluids or strong oxidizing agents
