Hopefully this is what you're looking for

Often called JIC or AN or 37° fittings, this size is commonly referred-to as -4 (4 x 1/16") or 1/4". The threads are 7/16-20 with a tapered 37° sealing face, and commonly used in hydraulics, military and auto racing. Search multiple terms with "cap" for best results. [EDIT] Note, these are not SAE, NPT, BSP, etc.

Check a local hydraulics supplier as often the cheap and quick option, and where I got mine for about $1 each. I found the brass type on Amazon for about $2 each in sets, or 10 plated steel on eBay (random example) for much less, aluminum more. Good luck!
