The Orbitrade 50 mm rubber stuffing box is a robust propeller shaft seal for marine installations, developed for a secure and watertight transition at the stern tube/shaft system. An ideal choice when replacing a worn stuffing box to minimize leakage and ensure stable operation.
The stuffing box acts as a seal around the propeller shaft and is suitable for maintenance and repairs where proper fit and material quality are essential. It is an obvious alternative when you want a reliable solution with easy installation and a long service life.
With precise dimensions (shaft 50 mm / stern tube 70 mm), you get a tight and stable installation that helps reduce water ingress and wear in the area around the shaft penetration. Always check dimensions and OEM reference before ordering to ensure full compatibility.
