Stuffing Box Detail information
The API 11B Oilfield Polished Rod Sealing Box, also known as a stuffing box, is an essential component installed at the Pumping Well Head. Its primary function is to seal the Polished Rod by utilizing cone packing and a lubricated upper section. This design allows for self-alignment, prevents packing burnout, and effectively seals against fluid pressure leakage.
There are two variations of the stuffing box available: Single Pack and Double Pack. Customers can 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 that are designed to match tubing EUE or LP connections.
These stuffing boxes are suitable for various 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 simple structure, which makes 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.
