Premium NBR HNBR FKM PTFE Hammer Union Seal Rings: Durable Sealing Solutions
Product Overview
Our premium hammer union seal rings are designed to provide exceptional sealing performance in the most demanding oilfield applications. Manufactured from high-grade elastomers including NBR, HNBR, FKM, and PTFE, these seals are engineered to prevent leaks and ensure operational safety in high-pressure fluid control systems. As a specialized manufacturer, we ensure that every seal meets rigorous quality standards to withstand the harsh conditions of drilling, fracking, and well intervention.
Application Scope
These hammer union seals are widely utilized across various sectors of the oil and gas industry. Key applications include hydraulic fracturing manifolds, cementing units, acidizing equipment, and mud pump systems. They are also essential for flow line connections, blow-out preventers (BOP), and manifold pipelines where secure, high-pressure containment is critical. Our seals provide a reliable barrier in both onshore and offshore environments, ensuring smooth operations in standard and sour service (H2S) conditions.
Material Comparison and Features
1. Nitrile (NBR): The most common material for general oil and water service, offering excellent resistance to petroleum-based fluids and a cost-effective solution for standard operations.
2. Hydrogenated Nitrile (HNBR): Engineered for superior mechanical strength and improved resistance to heat and abrasion, making it ideal for high-pressure drilling and modern oilfield chemicals.
3. Fluorocarbon (FKM): Known for outstanding high-temperature stability and chemical resistance, it is the preferred choice for applications involving aggressive fluids, acids, and high thermal loads.
4. Polytetrafluoroethylene (PTFE): Provides near-universal chemical resistance and can operate across a vast temperature spectrum, often used in specialized environments where elastomer limits are exceeded.
Working Pressure Ratings
Our seals are designed to accommodate the industry's standard figure series pressure requirements. For low-pressure systems like Fig 100, 200, and 206, the seals handle up to 2,000 PSI. Medium-pressure applications such as Fig 602 are rated for 6,000 PSI. High-pressure and ultra-high-pressure services, including Fig 1002, 1502, and 2202, are engineered to withstand working pressures ranging from 10,000 PSI to 15,000 PSI, ensuring maximum safety under load.
Operating Temperature Ranges
NBR Seals: Effective performance from -30°C to +100°C (-22°F to +212°F).
HNBR Seals: Enhanced thermal stability from -40°C to +150°C (-40°F to +302°F).
FKM Seals: High-heat capability from -20°C to +200°C (-4°F to +392°F).
PTFE Seals: Broadest range capability from -200°C to +250°C (-328°F to +482°F).
Why Choose Our Sealing Solutions
1. Precision Manufacturing: Each seal is molded to exact tolerances to ensure a perfect fit with standard figure union assemblies, reducing the risk of bypass or failure.
2. Durability: Our compounds are formulated to resist compression set and extrusion, extending the service life of the seal even under rapid pressure cycles.
3. Customization: We offer various profiles, including standard rings and lip-style seals with stainless steel or brass inserts for high-velocity flow environments.
4. Factory Direct Supply: As a direct manufacturer, we provide competitive wholesale pricing, consistent quality, and rapid lead times for global shipping.
