Modular Stuffing Boxes

Modular Stuffing Box

The MOST Modular Stuffing Box was designed to provide our customers with simple alternatives to maintain a wide range of operational requirements. The design allows the interchange of parts to go from a simple high pressure stuffing box to a pivoting unit that will self-align with the movement of the polished rod.

The Modular Stuffing Box gives our customers options that help them adapt to special service conditions. These options include the Pivoting Stuffing Box, High Pressure Stuffing Box and the Flapper Valve Stuffing Box.
