This is a piece that I've been wanting to make in stainless for a long time. It is a bit more expensive than brass but the fit and finish alone makes it worth it. This is a significant upgrade to the standard fitting as it's a T304 stainless fitting that is developed by Mosmatic and manufactured to high precision in Europe. You would use this to upgrade the inlet on your Mosmatic Spray Gun.
