Curtis Superior Fuel Quick Drain Valves
Curtis Superior Valve Co. Inc. has produced, engineered, manufactured, and tested aircraft valves to exacting standards since 1944. They have many standard valves to solve a wide range of problems.
- Corrosion resistant, stainless steel springs
- Specially compounded "cure dated" synthetic rubber seals to withstand a wide variety of liquids over a broad temperature range
- Unique wedge seal design prevents leakage
Thread: "UNF" (Fine thread) type are straight, non-sealing threads that rely on an o-ring to provide a seal. "NPT" (Pipe thread) type are tapered thread that seal as they are tightened. Measure the O.D. of the thread on the valve you are replacing and compare to the thread specifications table to determine the correct thread size.
Locking: Valve locks in the open position for easy draining.
Flush mounted: Valve is designed to mount flush with aircraft skin.
Use Pin Type Cup: Pin type cups similar to MCCCA-39680 may be used with indicated valves for sampling fuel.
Open Action: "Spiral" valves require a push and turn action to open. "Push" valves require a push action to open.
Hose Adapter Size: A hose may be attached to the valve for ease of draining fuel. The size is the hose I.D.

FAQs
How do I maintain my fuel and oil drain valves?
Curtis Superior and SAF-AIR valves are designed for installation in a standard NPT port for NPT threaded valves or an AND-10050 style port for UNF threaded valves. Use a thread sealant or Teflon tape on pipe threaded valves. Never allow any thread sealant on the first thread . This will prevent contamination of the fuel system. Refer to aircraft manufacturer's torque specifications for the aircraft in which it is being used.
Replace the rubber seals as per the aircraft manufacturer’s recommendations or every ten years when no guidance is given. McFarlane stocks replacement seals and seal kits for both Curtis Superior and SAF-AIR valves. The new Curtis valves use a O-ring type seal instead of the flat seal that was previously used.
SAF-AIR valves are designed to be disassembled and the O-rings replaced. Over time, if the valve should start to leak, check to make sure the drain valve is tight. If drain valve is found to be tight, then check the O-rings. All O-rings used are buna "n", MS29513 Style, MIL-P-5315. SAF-AIR O-ring seal kits are available for most of their valves. Add a "K" or "-K" suffix to the valve part number.
Never have a hose attached in flight to the oil drain valve. Engine vibration and the additional attached mass can cause premature seal and valve wear which could result in valve failure and a loss of engine oil.
How do I keep contaminants out of my fuel system?
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources McFarlane recommends the use of a fuel filter, such as Mr. Funnel or another filtering device, to reduce trash in the fuel system.
