Question Air Compressor CHeck Valve Needed!!!!

I have a Montgomery Ward Air Compressor, Model #75 6590, Ser #67C 42829. It's a two cylinder, single stage, 2 HP horizontal unit. I'm pretty sure the check valve needs to be replaced because the relief port on the check valve is leaking, indicating that tank pressure is backing up to the head.

I can not find replacement info for MW anywhere. I would use any other check valve if it had the same threads.

Does anyone have a cross reference for parts?? The check valve is in-line (some have individual lines from each cylinder coming in, mine one has one).

Please, please, please help!!

Remove it and take it to a place that specializes in air compressor parts.

If the original isn't available they should be able to give you the pieces to make something work.
