Stuffing Box Detail information

The API 11B Oilfield Polished Rod Sealing Box, commonly referred to as a stuffing box, is a critical component installed at the Pumping Well Head. Its primary purpose is to create a secure seal around the Polished Rod using cone packing and a lubricated upper section. This innovative design not only ensures self-alignment but also prevents packing burnout and effectively seals against any fluid pressure leakage.

The stuffing box is available in two variations: Single Pack and Double Pack, providing customers with the flexibility to choose the most suitable option. Depending on their specific requirements, customers can select either 1045/4130 casting steel or ductile iron for the cap, glands, body, and base of the stuffing box. The use of API gauged threads at the bottom of the box allows for seamless integration with tubing EUE or LP connections.

These stuffing boxes cater to a range of rod sizes, including 1 inch, 1.1/8 inches, 1.1/4 inches, 1.1/2 inches, and 1.3/4 inches. They are characterized by their straightforward structure, making installation and maintenance hassle-free. The option to choose between single packing, double packing, or even triple packing ensures optimal sealing effectiveness, providing customers with reliable performance and efficient sealing capabilities.
