copied from the above thread:
"The gas jets I use (as do the majority of UK/EU manufacturers and at least 1 American company) were originally manufactured by 'Calorgas' who eventually sold their camping gas division to 'TAYMAR'...... who were then bought out (taken over) by 'COLEMAN'.... an American company.
It is, therefore, possible that JetBoil get their gas jets from 'Coleman', with their own 'CUSTOM' markings on them...... if so then they would most likely be 1BA thread.

These gas jets are available (mail order) from the following (amongst others): -

www.roundhouse-eng.com

www.pollymodelengineering.co.uk Then look under the 'BRUCE ENGINEERING' section.

sizes commonly available are: -

Number 3 which has a 0.15mm dia jet bore

Number 5 which has a 0.2mm dia jet bore

Number 8 which has a 0.25mm dia jet bore

Number 12 which has a 0.3mm dia jet bore

Number 16 which has a 0.35mm dia jet bore

All have 1BA thread."

PS I hate bouncing from thread to thread.
