I had a leak in my fill valve/port O-ring a couple of months ago ………..
I’d try this before replacing the fill valve/port O-ring.
I used a little silicon grease place directly into the small inlet fill junction inside of the fill port.
I used a syringe fill with supper lube and injected a little right into this port or you can just use a tooth pick.
Connect to fill and give it a couple of good quick and hard blast of air with the fill valve on your CF tank, then slowly top fill.
The leak held and so far never returned ever since.
Great job with the video, look forward to future videos. I do have a question; would applying a small amount of anti-seize compound on the screws be a good idea to keep the metal screws from welding or seizing to the aluminum body or would sufficient torque prevent screw seizure. I’m talking all screws not any pacific ones on the Edguns. It seems that even with sufficient torque without over tightening these screws over time they do seem to become rather difficult to remove and just wondered if applying anti-seize be a smart thing or just further create other problems. Your thoughts please.
