Seals & Gaskets for Oil & Gas Applications
Seals and gaskets in oil and gas must contain hydrocarbons and withstand H2S, CO2, and other corrosive media. Fire-safe designs are required for many applications to maintain integrity during fire events.
Common Equipment
Wellhead equipment, pipeline valves, compressor seals, heat exchanger gaskets, tank seals
Selection Criteria
Fire-safe certification, sour service compatibility, temperature and pressure ratings, fugitive emissions compliance
Compliance Notes
API 6A for wellhead seals, API 600/602/608 for valve gaskets, EPA Method 21 for fugitive emissions testing.
Part Types
Diaphragms
Flexible membranes for pressure isolation
Expansion Joints
Flexible connections for thermal movement
Gaskets
Gaskets seal flanged connections in piping and equipment. Material selection depends on pressure, temperature, and media.
Hydraulic Seals
High-pressure seals for hydraulic cylinders
Mechanical Seals
Mechanical seals prevent leakage around rotating shafts in pumps and mixers. Use precision-lapped faces for sealing.
O-Rings
O-rings are circular seals with round cross-section. Widely used for static and dynamic sealing applications.
Oil Seals
Oil seals (lip seals) retain lubricants and exclude contaminants in rotating equipment. Feature flexible sealing lip.
Packing Seals
Compression packing for valves and pumps
Pneumatic Seals
Seals for compressed air systems
Rotary Seals
Seals for rotating shaft applications
