How to Fix & Repair Your HVLP Spray Gun: Step-by-Step Guide

What happens here

Before reattaching the nozzle, always pull the spray gun's trigger back or, even better, remove the needle entirely. This prevents any potential damage to the needle during nozzle reassembly. Carefully screw the nozzle back onto the gun. Tighten it by hand until it is finger-tight, then use a gun tool (like a spanner wrench) to give it a gentle snug. Avoid overtightening, as the precision machining of the nozzle and its tube ensures a perfect fit without excessive force. Once reassembled, the fan control ring should now exhibit the correct smooth resistance, indicating the gasket is properly seated and functioning.

Goal: Securely reattach the nozzle with proper tension and confirm the fan control ring's correct function.

flip that back and reset it I can put the gun back together again and if you're putting it together like this where uh you putting the nozzle in and you still have the needle in the gun then always make sure you pull the needle back because you don't want to put the nozzle in with any resistance from the needle it'll damage the needle and then once I've got it in there we only need to just snug the nozzle up we don't need to crank on it so just fingertight and then snug it and then now you can see there's a much difference in the in the way the the fan control ring feels so we've got the right amount of tension on it now so now I can I got that smooth resistance just like it felt you know I originally bought the gun now you know I used to take this tool and I would take this and I would tighten it up and I would tighten it up till all of a sudden I kind of felt it like just stop and it felt like it was like metal to metal so it's got pretty tight what you're saying is that's too tight or that's not right it's not necessary the way we machine the the um the nozzle and the inside of the nozzle tube the no the back of the nozzle has a little shamer on it and that shamer matches the chamfer inside the nozzle tube and because they're machined to such Precision they fit together perfectly you don't need to I can actually put this nozzle in the gun fingertight and it will not leave right so you don't need to tighten it up at all so I think um you know when I was talking to you about this um and one thing I just did right there I didn't pull the trigger back so you want to actually pull the trigger back always pull the trigger back or I just remove the needle usually from the gun yeah removing the needle is actually the best and safest way to do it what happens say if somebody was removing the gasket or they dropped the gasket in the grass and it disappeared can you purchase new gaskets and repace them through paint life Supply okay so um they are replaceable so damage it okay every gasket in the gun G every gasket every part in our gun is replaceable there's really not anything um that is can be damaged that much that can't we can't replace it or repair it so there you go troubleshooting the fan control ring it's all functioning properly and working out on the atomizer 7700 gun thank you John if you guys got any
