You can buy asbestos rope in China. It is available in numerous sizes and types and the makers will be happy to send you online catalogs. There may be some difficulty getting it shipped to the USA, however. It was as I recall finally banned for good in either late 2023 or 2024, so even if you manage to get somebody to send it to you...you will not be able to sell it without getting in trouble. Sellers in China are not supposed to send it over here anymore. I actually considered buying a spool of it which was graphite impregnated to sell as rear main seals but a friend who has been involved in mesothelioma work told me he thought the ban would be final before I received the stuff.
