Product Introduction
This curated catalog features genuine Cameron OEM elastomers, including CAMRAM 350 and CAMLast high-performance compounds, designed for critical BOP sealing applications. These elastomers are formulated to withstand extreme well conditions, with resistance to H₂S (up to 5%), drilling fluids, and wide temperature fluctuations (-30°F to 350°F/-34°C to 177°C). Unlike generic aftermarket seals, each component is precision-molded to eliminate gaps, ensure consistent compression, and maintain PR2 pressure ratings, delivering reliable well control and extended service life in harsh offshore and onshore drilling environments.
Key Functional Advantages
- Zero-Leak Pressure Sealing: Engineered elastomer compounds deliver full 10K psi pressure retention for ram BOPs and 5K psi for annular BOPs, preventing well fluid blowouts during drilling and well intervention.
- Chemical & Corrosion Resistance: CAMRAM 350 and CAMLast formulas resist H₂S, crude oil, and drilling mud degradation, reducing seal failure rates by up to 45% in sour gas environments.
- Temperature Stability: Rated for extreme temperature classes (BDF, CDF, EAD), elastomers maintain flexibility and sealing integrity without hardening or cracking in cold and high-heat well conditions.
- Durable Wear Resistance: Reinforced elastomer construction withstands repeated ram actuation and pipe handling, extending replacement intervals and reducing maintenance downtime.
- API Compliance: All parts meet API 16A 4th Edition PR1/PR2 requirements, ensuring regulatory compliance for global drilling operations.
Structural & Material Features
Cameron OEM BOP elastomers feature industry-leading design and material properties:
- Precision Compression Molding: Tight dimensional tolerances (±0.010”) for perfect fitment, eliminating seal misalignment and pressure loss.
- High-Grade Elastomer Compounds: CAMRAM 350 (85 Shore A hardness) and CAMLast synthetic blends for optimal flexibility and sealing force.
- Reinforced Core Design: Select packing units and rams include embedded inserts for structural stability under high-pressure actuation.
- Uniform Material Density: Molding process ensures consistent elastomer density, preventing weak spots and premature seal failure.
Applicable Operating Conditions
These elastomer parts are validated for the harshest drilling and well control environments:
- Equipment Type: 13-5/8” U Type Double Ram BOP (10K), T-90 Annular BOP (3K/5K), VBR variable bore rams, ISR shear rams
- Pressure Ratings: 3,000 psi, 5,000 psi, 10,000 psi operating pressure
- Well Conditions: Sour gas (5% H₂S max), onshore/offshore drilling, well intervention, high-pressure well control
- Temperature Range: -30°F (-34°C) to 350°F (177°C) across BDF, CDF, EAD temperature classes
Proactive Maintenance Recommendations
- Scheduled Inspections: Inspect all BOP elastomers every 30 days or post-well job; check for cracks, swelling, compression set, or chemical damage.
- Pressure Testing Protocol: Conduct API-compliant pressure testing after elastomer replacement to verify PR2 sealing performance at rated BOP pressure.
- Storage Guidelines: Store spare elastomers in a cool, dry, dark environment (60–75°F) away from UV light and chemicals to preserve material integrity.
- Replacement Interval: Replace ram packers and top seals every 6–12 months; annular BOP packing units every 12–18 months, or immediately if damage is detected.
- Spare Parts Stocking: Maintain both primary and backup elastomer inventories per this list to minimize BOP downtime during emergency repairs.

Field Failure Repair Case Studies
Case 1: U Type BOP Top Seal Leak & Pressure Loss
Issue: 13-5/8” U Type 10K BOP experienced severe fluid leakage around the top seal during pressure testing, halting drilling operations. Root Cause: Degraded CAMRAM 350 top seal (P/N 644707-01-00-01) with compression set and chemical damage from H₂S exposure. Solution: Installed genuine Cameron OEM top seal, torqued bonnet fasteners to OEM specs, and conducted a full pressure test. Outcome: Eliminated leaks, restored 10K psi pressure rating, and resumed drilling within 2 hours.
Case 2: T-90 Annular BOP Packing Unit Failure
Issue: T-90 Annular BOP failed to seal around drill pipe, causing well control risks during well intervention. Root Cause: Worn packing unit (P/N 2501992-03) with torn elastomer and degraded insert bonding. Solution: Replaced with OEM annular packing unit, adjusted closure tension, and verified sealing performance. Outcome: Restored full annular sealing, passed API pressure testing, and completed well intervention safely.
Case 3: ISR Shear Ram Side Packer Leak
Issue: ISR shear ram exhibited side leakage during pipe shear testing, compromising well control. Root Cause: Damaged side packer (P/N 2010985-01) with tears and hardness degradation from high-temperature well fluids.Solution: Fitted genuine Cameron side packer, realigned shear ram assembly, and retested pressure. Outcome: Resolved leakage, restored shear ram functionality, and met safety compliance standards.
Frequently Asked Questions (FAQ)
| Question | Answer |
| Are these Cameron elastomers compatible with non-Cameron BOP models? | No, these elastomers are custom-molded for Cameron 13-5/8” U Type, T-90, VBR, and ISR BOPs; dimensions and pressure ratings do not guarantee fitment on other BOP brands. |
| What temperature classes do these elastomers support? | Parts cover BDF, CDF, and EAD temperature classes, with operating ranges from -30°F (-34°C) to 350°F (177°C), suitable for most global drilling environments. |
| How do I confirm these are genuine Cameron API-compliant elastomers? | Genuine parts feature stamped OEM part numbers, include API 16A 4th Edition PR1/PR2 markings, and match Cameron BOP service manual material specifications. |
Procurement Guidance
Safeguard your BOP well control integrity, regulatory compliance, and rig uptime by sourcing only genuine Cameron OEM elastomers from this official parts list. Generic aftermarket elastomers often fail to meet API 16A standards, suffer premature chemical degradation, and cause dangerous seal failures — all avoidable by referencing the exact part numbers, temperature classes, and pressure ratings listed for primary and backup BOP sealing components.
