LOCK OPEN OIL DRAIN VALVES 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:

As has been pointed out by others, the crush gasket is loose on the threaded shaft, due to the threads no contiuing to the gasket contact surface, thus the gasket has no means of being centered when installed, increasing the likelihood of leakage. Otherwise, quality seems fine.

Fit my C150 with O-200 perfectly. FYI, it did come with a copper gasket, so I did have to buy one to install it after all. Also come with anti-seize compound.

Installed, but untested at this point. Anticipate much easier oil change in the future for my Cessna 150.

Great failsafe quick drain although there can be installation problems on small continental engines, especially those with dented/distorted/repaired kidney tanks or from over tightening the QD such that the crush washer is completely flattened. When installed, some QDs fail to lock in the open position. Nothing is wrong with the QD itself, rather the top of the drain hits the oil suction tube so the QD cant be extended far enough up to lock open. Installing the QD with a new crush washer or an extra spacer washer generally provides enough clearance for the QD to operate as designed. One comment was about the QD threads missing and leaking at the gasket. Please note the QD has straight threads as does the kidney tank. Straight threads not intended or designed to make a seal. Sealing is face to face with a copper crush washer in between the QD shoulder and the oil tank shoulder. All the QD threads do is pull the two faces together crushing the washer and forming an oil tight seal. If the QDl is weeping oil at the crush gasket, check to see if the oil tank face is cracked or damaged. I hope this note helps anyone who is having installation problems.

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. It’s awkward and uncomfortable when draining hot oil. Kind of defeats the purpose, doesn’t 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.
Leaked after 10 hrs flight time! Putting the original plug back in. 😡

It uses a 3/8" hose.
Per the manufacturer, we do not have a torque value. We recommend seating the crush washer and then a 1/4 turn. Do not over tighten.
