oil screen plug gasket

All,

I am corn-fused.

I am searching for a part number that is equivalent to AELSTD111 - this is the crush gasket for the oil screen plug in the sump on my ECI Titan O-360-A4B1.

A "generic" O-360-A parts catalog (which Jim Ball said would apply) shows a part number of STD111 for this little crush gasket.

A search on Spruce doesn't show that part. A google search led me to an Ebay link here - https://www.ebay.com/itm/New-copper...S35769-21-06E19769-1-00-STD-111-/161395260257 - but I'm not 100% sure this is the right fit because it only spec's the ID and not the OD. Which probably doesn't make a difference and maybe I'm being paranoid, I just want to do this right.

Is the one on that Ebay link ok to use? Is there a part number Spruce has that is better that I'm just not seeing?

Sorry. I know this is a 101-level question.

You want this

Part# AN900-16
MFR Model# MS3576921

$0.54 .. a MUCH better deal than what you found on ebay

N520TX beat me to it, but that is the correct part

And....buy a dozen of them - that way you’ll have enough for several years worth of oil changes, and you’ll have NO EXCUSE not to check the suction screen very time.....

Also, these are "torqued" by an angular rotation after making contact, not by a torque value. once the gasket makes contact you turn it an additional 135 degrees. That is 2-1/4 flats on the hex.

Also the split side should be against the non rotating surface. In this case of course the sump.

Thanks, all.

The plug has been the source for one of my leaks so I torqued it up a bit today and re-safety wired it.

Three times. Because I'm learning.

Anyway - appreciate the info. Feel like I'm going to owe this forum an entire liquor store's worth of beer and bourbon before I'm done with this airplane.
