Hy guys.

My Jetcat came with these quick disconnect fittings. Could it be use in the fuel lines, or just starting gas only? Thanks.

I use these for all my jets for fueling, never had any problems

Thank you for the info. I plan to use these in the fuel system for my helicopter since the mechanic may have to be remove for maintenance periodically, and it is much easier to disconnect these in tight space than Festo.
