Design principle
When hydraulic fluid is pumped into the closing port it fills the closing chamber below the piston, causing the piston to rise. The rising piston pushes on the seal element which then rides upwards and inwards on the spherical profile of the lid. As the sealing element is squeezed into the well bore, it will contact and seal on any size or shape of object in the well bore. If there is no object in the bore, the sealing element will continue to squeeze shut until it seals of the entire bore.

Annular BOP Packing Element
Academy Petroleum Industries 5 1/8" - 10,000 Annular BOP Packing Element has been designed to our specifications to ensure proper fitment and operation with our 5 1/8" - 10,000 Annular Blow Out Preventer. Our Packing Element is based on a time tested and field proven design used successfully in the oilfield for many decades. The Packing Element is designed, manufactured & tested in accordance with the stringent requirements set forth in API Specification 16A.
Academy Petroleum has specified superior materials for use in its construction, resulting in reliable sealing performance under a wide range of operating conditions. The steel reinforcing inserts are made from high quality low alloy steel that meets the requirements of NACE MR0175 for sour service applications. The elastomeric compound used in this Packing Element is Hydrogenated Nitrile Butadiene Rubber (HNBR), also known as Highly Saturated Nitrile (HSN). HNBR is used widely in the oil & gas industry particularly where Hydrogen Sulfide (H2S) gas is present due to its ability to withstand a wide variety of oils, fuels, and other chemicals. HNBR exhibits good weathering resistance and excellent mechanical properties in terms of tensile strength, tear modulus, elongation at break and abrasion resistance.
Our Packing Element design has been tested rigorously in accordance with API Specification 16A to ensure proper functionality and reliable sealing performance. In addition, each Packing Element is thoroughly inspected and fully function tested in accordance with API Specification 16A prior to leaving our facility.
