F391-82 Quick Drain Valve, 1/2-20 Thread. Specially designed for use in aircraft fuel systems.
The F391 flush valve from MDI Aerovalve is used as original equipment by most aircraft manufacturers and has been FAA/PMA approved for replacement parts.
This flush fuel drain valve is designed to be practical, functional, and inexpensive. The head of the valve does not extend beyond the wing to catch the door of your airplane or to hit your head as you walk beneath it. Fuel is only released when you want it to be with the use of our F391 fuel sampler cup, not all over your arm or in your eyes on a windy day.
Applicability: For Cessna 206, 207, 210 or aircraft with 1/2 inch 20 threaded fitting (Cessna part #S2020-2)
FAA/PMA approved
Fuel sampler cup sold separately (part number F391-CUP
Best priced around great and speedy service!
Also is the better of the 2 options since it is rated at 5,000 psi, not that I go to that high of pressure but I like the safety and security knowing that my chances of it blowing up in my face are a whole lot better and I can also purchase replacement seals for them at the same shop!!!
I bought the DC PTT because I know and trust the DC quality/durability to hold up to using every day. And so far it’s the best PTT I’ve used. I have a couple other no-name PTTs and the cable sheathing is crumbling and falling off. The DC PTT has worked even in sub zero cabin temp conditions when I didn’t have a functioning heater. I bought two to have a spare but the first one has been working great for 300hrs so far.
