Specially manufactured for high-temperature oil-based muds!
6" 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: 4" (DN150)
• 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
Reduces fugitive emissions by 83% per EPA Method 21
Meets API 682 seal class IV requirements
