All of the turbines I have ever owned have festo fittings for fuel input. Is this a problem over time on the engines themselves? I have never had an issue but am surprised the turbine mfg. use them based on your statement.

Good question.
Historically, Jetcat came with the Festos because they were the only German made connectors available 20 years ago.
They never considered Legris because they were French made at this time ( now USA made, Legris got bought over by Parker over 10 years ago ).
Legris fittings are much more resistant to fuel because their body is made of reinforced nylon ( this is what we use for all our military/ industrial setups ). however, even Legris does not certify their fittings for fuels as the internal o'ring is also nitrile.
For 100% reliability, the way to go is metal fittings. However they are heavy.
Note that I am designing a new line of Al606s barbed fittings that are feather lights.
They will be available very soon on our store.
