NITROUS OXIDE ( nos / n2o ) advice forum

Do anybody know the thread size for my mini bottle valve. I'm sorting the pipe for refilling my bottles but I don't know if the thread size is 4 or 5 mm. It's the latest won mini valve. . Fitted to 20 oz bottle Thanks in advance

It could be either 4 or 5 mm. To determine which it is you can either;

1) Measure the pipe OD

2) Send me a pic of the valve and inlet thread and I'll tell you which it is.

The od is 5 mm. It's the black nylon pipe supplied with the sb75 kit .thanks

Glad that's sorted then!
