IF they say it's okay, you're good to go. I've only used the blue silicone hose on coolant lines and the stuff, though pricey, is amazing. After 15 years on a 582 install (with a lot of outside time) it's still as supple as new. Over time it pays off in replacement costs and time spent. For your application I would recommend you run fire sleeve over it though. Best of luck and safe flying, Rick On Fri, Feb 21, 2020 at 1:05 PM Robert Toth wrote: > > > John I believe silicon is fine just watch the routing around the exhaust. > I have them on my 912 > > Sent from my iPhone > > > On Feb 21, 2020, at 1:53 PM, JohnFrance <77alembert@gmail.com> wrote: > > > 77alembert@gmail.com> > > > > Hello, > > I am replacing the hoses on my 912 and I am thinking of using silicon > hose for the oil return line.
