I still can't work out what's changed. What ss cover? do you mean the vent?

It's basically the old part without the o-ring, plastic washer, and stainless steel cover. Just went on ESG, and they have the new version "(Without SS Cover And Plastic)". Of course, the new item is 26.26, but I paid the price of the old version at 28.84.
What was the purpose of the stainless steel cover? More support for the battery in telescopic mode? To prevent the axis pin from getting stuck down in the axis?
