Tap/thread size to add 4mm fitting to direct port manifold

[Richard L]

The aquamist jet thread is M8 x 0.75mm
You can order the tap from : www.aquamist-direct.com

If you have room, it is better to order a 1/8NPT jet adaptor. The 1/8NPT is quite common in the US, so save yourself a few dollars by not ordering the M8 x 0.75mm tap (quite expensive)
