Part 550-270 is a replacement S-7 airless spray gun designed for Hydrax 4540–7230 equipment. It delivers controlled material flow and consistent atomization for smooth, high-quality finishes.
When the original spray gun becomes worn, leaks, or loses performance, replacing it restores proper spray control and reliable application results.
