hi buddy,,, i can help if you send me the marker,, i can see what i can match up,,
as for lube,, on any thing that has orings you need to use a non oil based lube.
i make a very high end teflon /silcone /lithium mix,, which is may be the best lube you can put in a marker,, but any thing silicone based,
but be warned there is some really crap stuff out there,,i had one lubing his luxe with tiger balm..which he bought from a paintball shop in france,,and he was told it was lube,,,i have allso seen hair cream ,, i kid you not,
if its from china dont use it,,
