True, he did, but I wanted to make clear that the tape is not incompatible with the hydraulic fluid; it's the possibility of sheared off pieces that are the problem.

Unless it is a parallel thread, in which case a (dowty) bonded seal is the answer

Many thanks

Late reply, sorry.

Seastar Helm seal kit (for most single station helms) is HS5176. Includes a body gasket, a shaft seal, and several O-rings. Price is around $50 US, as far as I can tell.

You can also get just the shaft seal alone (Quad ring seal, 3/4"ID, 1"OD) for a buck or two. Seastar Seal part number is 225226.

Most (but not all) steering cylinders are now using HS5157, which includes the 2 glands, some new O-rings for the nipples and hoses, a wrench, and a, insertions guide tool. Around $100 US.

Quite a few people in the US are suggesting taking the old seals to a local hydraulic shop and having them match seals. Saves money, I suppose. I do not advocate this (for my safety), but am only putting it out there as an option.
