Read a few times that people still recommend it even with the new style. But there is no mention of a weld being needed on the fitting instructions. Maybe the washers prevent any damage?
So do you need to? If so why?
If welded wouldn't it make it impossible to get back off/replace at a later date if needed?
Cheers
