FX 1st time an issue of non return filling valve of FX guns on the pattern of Impact and Royal etc.

The non return valve system for filling the bottle on almost all FX guns is very reliable. Specially with the quick connect type system I never found any issue in the past. Very simple and easy valve.

But we never know when things would go South.

Following video shows how I fixed the non return valve of a FX Royal 400 through modification.

Thanks for posting, I'll check it out!

Four FX and no issues (at all) but always good to know about fixes!

Cheers!

Thank you for sharing your thoughts and fixes Mubhaur.
I have not experienced that particular issue as of yet, but I now know exactly how to address it, if it occurs.
