Does anyone know the thread size for ordering poly caps to fit on the 60ml boston rounds from river supply? Couldn't find anything searching the sub and on the details from the product page They come with dropper caps not ideal for long term storage. Greatly appreciate any help, thanks in advance.
what you want is These from BCF - they fit perfectly
glassbottleoutlet had better prices than river for those, back in october at least, and it's easy to match the polycone caps and get those as well. give it a look if you haven't.
I recently emailed them. The neck finish is 20/400
I emailed them and they told me 18 Din. And Odie’s link has 18-400
I bought those exact bottles and those exact caps. Regardless of the numbers, I can say from first hand experience - they work fine. I wasn't sure at first - so I tested it. Filled the bottle with water, capped it, and turned it upside down. I let it set for like that for several days and there was zero signs of leakage.
That’s interesting. Did you perhaps check the finish of the 30ml bottles? This is the email I received.
