Thank you for your question. Although it depends on both the compatibility of the neck finish and the height of the bottle, many of our 32 oz. bottles are likely too large for this pump. As this pump accommodates 24mm 24-410 neck finishes and the dip tube is about 7-3/4" long, many of our 32 oz. bottles feature both a larger neck finish and are too tall to accommodate this length of dip tube. For example, Part #30WA31
, 32 oz. Dark Amber PET Plastic Boston Round Bottle, 28mm 28-410, is compatible with 28mm 28-410 closures and has a height of 8.286". Not only will the neck finish of this bottle (28mm 28-410) be incompatible with this pump (24mm 24-410), the dip tube will end about 3/4" from the bottom of the bottle. Thank you for choosing The Cary Company.
