Description
Annular BOP Packing Element
API 16A Annular BOP Packing Element for Oilfield Well Control Systems
SD Hydril manufactures high-performance Annular BOP Packing Elements designed for oil and gas drilling operations, well control systems, and pressure control applications.
Our packing elements are engineered for reliable sealing performance under high-pressure and high-temperature drilling environments. Available in spherical type and tapered type designs, SD Hydril packing elements are interchangeable with major annular BOP brands including Hydril, Shaffer, Cameron and other OEM well control equipment manufacturers.
Manufactured with premium elastomer materials and reinforced metal inserts, our BOP packing elements provide excellent wear resistance, extrusion resistance, and long service life.
Product Overview
The Annular BOP Packing Element is the key sealing component installed inside an annular blowout preventer.
During drilling operations, the packing element closes around:
- Drill pipe
- Drill collars
- Tool joints
- Casing
- Open hole sections
to prevent uncontrolled release of formation pressure and maintain well control safety.
Annular BOP packing elements are widely used in:
- Oil drilling rigs
- Gas drilling operations
- Workover operations
- Geothermal drilling
- Offshore drilling platforms
Types of Annular BOP Packing Elements
Spherical Packing Element (FH Series)
The spherical packing element provides excellent sealing performance through radial compression toward the center of the bore.
Features:
- High sealing reliability
- Long service life
- Suitable for frequent opening and closing operations
- Excellent stripping performance
Available models:
- FH18 Series
- FH23 Series
- FH28 Series
- FH35 Series
- FH48 Series

Tapered Packing Element (GK / GX Series)
The tapered packing element uses a conical sealing design, reducing wear during operation and improving service life.
Features:
- Lower operating friction
- Better wear resistance
- Suitable for high-cycle drilling operations
- Easy replacement and maintenance
Available models:
- GK Series
- GX Series
