When assembling traditional installations made of pipes and threaded fittings, it is necessary to seal the connection well. This can be done traditionally by winding the hemp fibers on the external thread and then lubricating them with linseed varnish. It is more modern to use a special Teflon tape. It is also wound on the external thread, but does not require lubrication with varnish. It is characterized by very high durability in water installations, hence it displaces cannabis very effectively.
