The other thing I meant to say is that aluminum to aluminum will gall easier than brass to aluminum. I work with aircraft flight controls and sometimes we have a hell of a time with galliing of threads when the materials are the same kind, like stainless to stainless and a lubricate is not used during assembly. If you do not carry a lubricant you have one your body produces, wipe the nose grease off you nose and apply to the threads it will help the threads from galling. No joke it works. May father used to fix watches and an old watch maker from the early days taught him that nose oils are extremely fine and good to oil watches in a pinch or in this case threads of a filter.
