Got a set of used nx carbon solenoids. I got them off here and plans changed so I'm selling them. They work fine I've hooked them up to 12v and they click on and off fine. Guy said he probably had 30, 10 pound bottles, through them. Part numbers on them are 15200L and 15201L. 200 shipped obo. Shoot me a text at 270-84four-2001 for quickest response.
