Product Introduction
Our genuine NOV spare parts cover high-criticality drilling equipment categories: BOP sealing kits (SBOP 18-3/4 10M), mud pump pressure gauges, hydraulic elevator components, Airflex brake assemblies, riser wear parts, H2S-resistant RTJ flanges, and precision fasteners. Sourced directly from NOV’s US, Norway, and German manufacturing facilities (including Shaffer, EATON Airflex, HAWE Hydraulik), each part carries full OEM certification, with matching part numbers (e.g., NOV 6609 insert bowl, 89213001412 Airflex brake) for direct drop-in replacement. All components undergo non-destructive testing (NDT) and pressure validation to ensure compliance with global drilling safety norms.
Functional Capabilities
- H2S-Resistant Sealing & Pressure Containment: RTJ flanges, BOP seal kits, and nitrile O-rings deliver reliable high-pressure sealing (up to 70MPa) in sour gas (H2S) drilling environments, preventing fluid leaks and blowout risks.
- Precision Pressure Monitoring: 0-10,000 PSI mud pump flanged gauges and 0-70MPa hydraulic pressure gauges provide accurate real-time pressure readings, ensuring safe equipment operation.
- Reliable Braking & Control: EATON Airflex 16VC600 brakes and twin solenoid valves enable responsive pneumatic/hydraulic control for drilling drawworks and rotating equipment.
- Casing Handling & Tool Compatibility: BJ type HT-55 lug jaws, insert bowls, and hydraulic elevators ensure secure casing handling for 3 1/2” to 13 3/8” casing sizes.
- Wear Resistance & Longevity: BOP wearbands, slip-joint wear sleeves, and polypack seals withstand abrasive drilling fluids, reducing frequent replacement needs.
Structural Design Features
- OEM Exact Fit: Precision-machined dimensions matching original NOV equipment designs, eliminating installation errors and compatibility issues.
- H2S-Compatible Materials: NACE-compliant nitrile rubber (70-90 duro), 316 stainless steel fasteners, and corrosion-resistant alloys for sour gas service.
- High-Pressure Construction: Reinforced seal assemblies, RTJ flanges, and bonded bolts rated for 10M (10,000 PSI) pressure service.
- Modular Replacement Design: Pre-assembled seal kits, brake friction linings, and cartridge components enable fast field repairs to minimize downtime.
Applicable Operating Conditions
These genuine NOV spare parts are validated for extreme drilling environments, including:
- HPHT (high-pressure high-temperature) drilling with pressures up to 10,000 PSI (70MPa)
- Sour gas (H2S) onshore/offshore drilling operations (NACE MR0175 compliant)
- NOV Shaffer BOP systems, mud pumps, riser joints, and casing handling equipment
- Offshore platforms, jack-up rigs, and land-based drilling rigs
- Abrasive drilling fluid conditions and continuous 24/7 rig operation
Maintenance & Service Best Practices
- Inspect BOP seal kits, polypack seals, and O-rings every 1200 operating hours; replace components immediately if cracks, hardening, or wear are detected to maintain pressure integrity.
- Calibrate NOV pressure gauges (0-10,000 PSI) every 6 months to ensure accurate pressure monitoring, per API calibration standards.
- Check Airflex brake friction linings every 800 hours; replace linings if wear thickness exceeds 2mm to preserve braking efficiency.
- Lubricate hydraulic elevator and casing handling components with API-certified grease to prevent jamming and corrosion.
- Tighten NOV Bondura bolts and stainless steel screws to manufacturer torque specifications to avoid loosening from rig vibration.
- Store H2S-resistant seals and O-rings in a cool, dry environment to prevent premature degradation before installation.

Field Failure Repair Case Studies
Case 1: BOP Seal Failure in H2S Drilling
An offshore rig experienced BOP pressure leaks during sour gas drilling, caused by degraded non-genuine polypack seals. Installing genuine NOV SBOP 18-3/4 10M polypack seals (p/n 20075585) restored full pressure containment, ensuring compliance with H2S safety standards and resuming drilling operations.
Case 2: Mud Pump Pressure Gauge Inaccuracy
Faulty aftermarket pressure gauges provided false pressure readings, risking mud pump overpressure. Replacing with genuine NOV 0-10,000 PSI flanged gauges (p/n 661561-10) delivered accurate pressure monitoring, preventing equipment damage and operational delays.
Case 3: Airflex Brake Malfunction
Worn friction linings caused unresponsive drawworks braking, creating unsafe hoisting conditions. Fitting genuine NOV EATON Airflex brake assemblies (p/n 89213001412) restored reliable braking performance, meeting rig safety protocols.
