Stuffing Box Detail information
The API 11B Oilfield Polished Rod Sealing Box, commonly known as a stuffing box, is a crucial component installed at the Pumping Well Head. Its main purpose is to seal the Polished Rod using cone packing and a lubricated upper section. This design ensures self-alignment, prevents packing burnout, and effectively seals against fluid pressure leakage.
The stuffing box is available in two variations: Single Pack and Double Pack. Customers have the flexibility to choose between using 1045/4130 casting steel or ductile iron for the cap, glands, body, and base, depending on their specific requirements. The bottom of the stuffing box is equipped with API gauged threads, designed to match tubing EUE or LP connections.
These stuffing boxes are suitable for 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 a simple structure, making installation and maintenance hassle-free. The option of single packing, double packing, or even triple packing ensures optimal sealing effectiveness, offering reliable performance and efficient sealing capabilities.
