The left tank was updated like this and I was told the 1/8 thread went straight in and sealed but I can't get the right side to bite - I realise the thread on the SAF is 3/8 24tpi -3 which is parallel and a similar diameter but different thread pitch. I'm unclear if the SAF valve removed from the other side was in fact a 1/8 NPT version as these are available and I'm unlucky to have a rogue thread on the other side. I tried replacing the SAF 180 but it went in nicely but keeps spinning as the thread bottoms out - it would seem it has gone past the threads or something is loose ! Just wondering what you guys have - anything other than 1/8NPT ? Also I have the caps with the Zeus type slotted screw to close/lock - are there any items that will retro fit with a tab or something easier than using a screwdriver to grip the wire ?
