The ones I have for the HW44 go in easy, but they all leak at the joint where the Foster end screws onto the Weirauch fill valve.are they tight when you insert them, or do they go in easy?
does the tight happen when you try to remove them after a fill? do you bleed the air hose before removing probe?
are the o-rings the right size?
? did you buy new probes from AoA and Midway and they both get stuck?
