EB-620 sealing wire set
The idea of the sealing wire set is to
replace the sealing wire and the PTFE tapes at one time
fast with minimal tool requirements. In case that any of these parts is worn off, it is suggested to change all three items (sealing wire + lower PTFE + upper PTFE) at the same time. This way it is assured, that after changing the ware parts the expected lifetime can be maximized.
For easy storage the sealing wire set is shipped in a round plastic box. This way it is assured, that the sealing wire and the PTFE tape will not be damaged.
