Despite the availability of modern dripless seals, most boaters still rely on the old-fashioned type of stuffing box to stop water penetrating the boat past the propeller shaft.This type of stern gland has a small chamber filled with rings of flax packing. The flax is squeezed closely around the shaft by a plunger turned by a large nut.The pressure on newly installed flax is adjusted so that when the propeller shaft is not turning, the gland will admit a flow of about four drops of water a minute. When the flax has bedded in after 10 or 15 hours of running, it should be adjusted again for a rate of one or two drops a minute when the shaft is still. When the shaft is turning, of course, the rate will be somewhat greater; the water will not only lubricate the gland, but also prevent overheating of the shaft where it passes through the stuffing box. This is a simple and reliable


The traditional and still common stuffing box(above) depends on a few drops of seawater around the rings of flax packing for lubrication. The more complicated dripless shaft seal(top right) utilizes a rubber bellows and carbon-graphite ring
system that has been in use for many decades.Conventional flax packing is square in cross-section. Some brands are impregnated with synthetic lubricants such as polytetrafluoroethylene (PFTE) or Teflon; others are braided from synthetic yarn.Dripless seals come in two forms: (1) a simple claylike lubricated material that conforms to the shape of the stern gland when you stuff it in, creating a permanent waterproof seal; and (2) a more complicated form that relies on a mechanical seal between the stuffing box and the propeller shaft. This second type holds a stationary, high-density, carbon-graphite flange against a stainless steel flange on the propeller shaft, and the shaft where it passes through the boxis enclosed in a nitrile bellows.

Thanks Nikki. Your references were very helpful, particularly the 1st one about Stern Glands and the 3rd one about the term "presse etoupe de ligne d'arbre" on the bilingual website of a submarine constructor, which had an equivalent English page with the term "stern gland". Yes you're right, I should have asked the whole term together "presse étoupe de ligne d'arbre", I was afraid of being told off by moderators for trying to fit two terms into one! Thanks also to the other answerers.
