Is there a reliable sediment bowl O-ring out there?

I've got a 54 NAA. I replaced the sediment bowl assy. with a new CNH part a few years ago. The aftermarket ones are junk.

The valve on my current sediment bowl works and shuts off the fuel. However, I cannot get the bowl to stop leaking no matter how tight I get it. When the fuel is turned on it just drips ever so slightly and runs down the bowl and drips onto the hydraulic pump. About one drip a minute, but enough to make a mess.

I've used the cork gaskets, and rubber replacements from Tisco and others. I've had the bowl off numerous times and cleaned everything.

I'm thinking about getting another rubber one and using some Permatex to seal it.

Is there a better aftermarket O-ring that will seal and stand today's fuel?
 
I have had good luck with cork gaskets (not cork/rubber composite) but very poor luck with the neoprene ones.

Remove the bail and thoroughly clean and lubricate the threaded rod. I use a wire wheel and anti sieze.

Use a new gasket every time you remove the sediment bulb. You will need to retighten the bail at least once sometime after installing a new gasket.

O'Reilly's part #398 fuel strainer gasket. O have one right here on the desk just so I have the number handy. It is a cock rubber one. Drop it in some gas for say 3 minutes then install it. I have had almost no problems with that gasket and when I did it was caused by a chipped bowl or a problem with the holder it self
 
I'll have to try to find an all cork one. I've been using the rubber/neoprene ones and the cork composite ones. I'll have to look into the O'Reilly's one also. Is that a local parts store? Or, can you order them on-line somehow? I'm not familiar with O'Reilly's in my area. (SE PA)

My bail and threads are clean and anti-siezed. It seems I've had it on and off a dozen times in the last few months. I try not to overtighten and keep snugging it up a little but the leak will stop for a short time and then continue.

I'll have to check the bowl for a chip next time I take it off.

I'll keep trying. Thanks for the responses.
 
O'Reilly's is a part store chain sort of like NAPA and is well known in the mid west. That part number if given to NAPA should get you the same part since it is made by some other company any how. By the way this package says made in the U.S.A on it
 
I use NAPAs cork-rubber sheet gasket material. It swelled a little bit but sealed just fine. #3026 Fel-Pro 3/32".
