Contents • • • • • • • • • Components [ ] A stuffing box of a sailboat will have a stern tube that's slightly bigger than the prop shaft. It will also have packing nut threads or a gland nut. The packing is inside the gland nut and creates the seal.

The shaft is wrapped by the packing and put in the gland nut. Through tightening it onto the stern tube, the packing is compressed, creating a seal against the shaft.

Creating a proper plunger alignment is critical for correct flow and a long wear life. Stuffing box components are of stainless steel, brass or other application-specific materials. Gland [ ] A gland is a general type of stuffing box, used to seal a rotating or reciprocating shaft against a fluid.

The most common example is in the head of a tap () where the gland is usually packed with string which has been soaked in or similar grease. The gland nut allows the packing material to be compressed to form a watertight seal and prevent water leaking up the shaft when the tap is turned on.

The linear seal around the of a double acting steam piston is also known as a gland, particularly in marine applications.

Likewise the shaft of a handpump or is sealed with a gland where the shaft exits the borehole. Other types of sealed connections without moving parts are also sometimes called glands; for example, a or fitting that connects a flexible electrical conduit to an enclosure, machine or bulkhead facilitates assembly and prevents liquid or gas ingress.

A small boat stuffing box comprising an adjusting nut, a locking nut and a sleeve. On a boat having an inboard motor that turns a shaft attached to an external, the shaft passes though a stuffing box, also termed a 'stern gland' in this application.

The stuffing box prevents sea water from entering the boat's hull. In many small boats, for example, the stuffing box is mounted inboard near the point the shaft exits the. The 'box' is a cylindrical assembly, typically of bronze, comprising a sleeve threaded on one end to accept adjusting and locking nuts. A special purpose heavy-duty rubber hose attaches the stuffing box to a stern tube, also called a shaft log, that projects inward from the hull. Marine-duty secure the hose to the stern tube and the stuffing box. A sound stuffing box installation is critical to safety because failure can admit a catastrophic volume of water into the boat. In a common type of stuffing box, rings of braided fiber, known as shaft packing or gland packing, form a seal between the shaft and the stuffing box.

A traditional variety of shaft packing comprises a square cross-section rope made of or impregnated with wax and lubricants. A turn of the adjusting nut compresses the shaft packing. Ideally, the compression is just enough to make the seal both watertight when the shaft is stationary and drip slightly when the shaft is turning. The drip rate must be at once sufficient to lubricate and cool the shaft and packing, but not so much as could sink an unattended boat. The market offers improved shaft packing materials that aim to be drip-less when the shaft is turning as well as when stationary.
