QUESTION What is the inner diameter of this spout? I have a bottle with an approx. outside screw neck of 1 7/8". Will this spout fit my bottle?
ANSWER Hello, these caps are standardized to fit any bottle which is a M38 SP400 neck finish. The diameter is approximately 1.483", and most likely will not fit 1-7/8". If you know the model of your current bottle, we may be able to help you find the correct replacement spout. For assistance, our customer service department can be reached at 1-866-634-8927.
