Please note: These replacement rubber bulk heads manufactured by ASM may not have the exact perfect shape as the ones that came with the skimmer you bought and may have a slightly imperfect cut.
Also please note that, if you have an older G-1 skimmer these rubber bulk heads may not fit anymore as ASM has slightly changed their design. The original hole in the old skimmer is smaller and drilled lower than the new ones.
