Hi,

Can anyone recommend some 6ba oil cups please,seen a few but they all seem open topped which will let contanination in.

Can you not make a couple they are easy enough to do.

These ones would be about the right size for a 6BA thread although in this case they are flange mounted

Here you go, if its not obvious the hole in the body is the tapping size for 7/32×40, and teh OD may need to be a fraction less than 1/4" , just enough to remove the hex. Click for a bigger image.
