The original Nautilus seems to have a "non standard" drip tip size. The tip supplied fits nice and snug but replacement standard tips are very loose. Also, the supplied tip does not fit into my Kayfun 3.1 which indicates it is indeed a larger tip (not by much but it is larger). I currently have a muffler style tip on my Nautilus but I had to wrap a small amount of electrical tape around the o-ring area just to keep it from falling out when tipping the device. Can you confirm this is the case and would it be possible to make future Nautilus products more compatible with third party drip tips? Thank you.
