Salam alaykum shaykh. I have one question.I work in Bosnia as sales representative in company that produce and sale gases. Some of our customers are companies that produce weapons and arm equipment. I do not know for what they use our gases, maybe maintenance of their own equipment or in direct process of production, I do not know in which purpose. Some of that companies cooperate and sale weapon to countries that are in war with muslims (USA, Israel). I think they do not sale strictly weapon just to these countries, maybe they produce it also for our state needs, but sometimes in official state reports about weapon export from these companies they mention USA and Israel. Is haram for me to cooperate with such companies and sale gases and equipment for gases to them and is that act of kufr (helping kafeers against muslims) or in this case I can sale gases to them while that companies are responsible to whom they will sale weapon ? May Allah bless you.
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Your work as a representative of that company that produces gas is permissible. The details you mentioned in your question do not affect its permissibility, let alone rendering your work in it as an act of Kufr (disbelief).
Allah knows best.
