MFR Model# S6250


Changing hot engine oil has never been easier! With the SAF-AIR oil drain valve, no wrench is needed to remove the drain plug. A simple push and turn of the SAF-AIR valve locks it in the open position. The valve is made completely from anodized aluminum and stainless steel components. These materials are used throughout the aircraft industry due to their strength and durability. FAA & PMA APPROVED.

Product Notes:
  1. NEVER fly the aircraft with the drain hose attached to the oil drain valve.
  2. Make sure that your landing gear will not activate the oil drain valve when you retract the gear inside the fuselage.
  3. Remember, the valve may fit on your engine, but it is your responsibility to make sure that the valve will work with your application.

My S6250 will not stay in up and locked open position. When lifted all the way up, the blue gnarled grip ring just turns around and around. So, I have to kneel there and hold the quick drain in the open position in order for it to drain. Itâs awkward and uncomfortable when draining hot oil. Kind of defeats the purpose, doesnât it? Previous owner installed it shortly before I bought the plane. Stopped working after three or four changes. Not sure I trust buying another one at those prices and no warranty.

The 5/8-18 threaded SAF-AIR valve has a serious defect in the manufacture of the valve. The threaded portion of the valve does not extend to the installation gasket (AN900-10 copper crush washer) seal surface. The threads have been cut away in that area leaving the 1/8 inch section where the seal washer is undersize. Therefore there is nothing to hold the seal washer centered on the valve and the seal washer will or may move off center when the valve is torqued. Being off center leaves the seal washer in such a way that because it is off center there will be a seep oil leak result. Either the threads should not be removed from that area or the now reduced diameter of the valve body should be left in full 5/8 inch diameter so the seal washer will remain centered and do a proper job of sealing the installation.
