Bought one in MAY 2023 & believe the manufacturer read all the reviews, making necessary adjustments. Was looking just for a sealing ring to replace the silicone ring I bought as I was not getting a good seal & was constantly cleaning up a nasty oil mess. New dipstick very much solved the problem & secures well, yet does not require Hercules to remove. Am buying a few more to replace on other O-200s we are rebuilding.

Worked fine for my continental 0200

will have to return. I thought that it would fit a Lycoming engine. Is a well maid item. Just want be able to use it.

Very hard to get fully seated on oil tank neck

On my C-85, it didnt work so well. It came loose after about 10 min of flight. Made a bit of a mess. Fixed by adding a second gasket to snug it up. Seems to work now. Original equipment was spring loaded. Could not find a similar one on the market.

Second one of these dipsticks to break off at the spot welds in an O-200 with less than 50 hours. AP/AS will not allow you to return for refund. Instead they send you to Wag Aero

Mine also broke the spot weld, at about 40 hours. It gets one star because it looked good and screwed on tightly while it lasted.

Spot weld broke at about 50 hours

The cap does not fully tighten resulting in it unscrewing in flight and causing a big mess. The thing needs a thicker gasket. Note to self - Read prior reviews before making a purchase!

The spot weld will break. Period. They last about 150 hours, and then the spot weld holding the stick to the cap breaks. The only good thing is that theyre available. I cant find another one anywhere else. So, Im buying my third one.

Mine broke after 15 hours... keep in mind this is a Wag Aero product... Save your money.

I have had two. The first one broke a spot weld and the second will not stay seated. Cap came loose 3x already in flight. Save your time and money with these caps and look elsewhere.
