Part number 0277178 is a Tube specifically engineered for the SprayTech HVLP Maxum II spray gun systems. These professional-grade HVLP spray guns are designed to deliver high-quality finishes with minimal material waste, making them ideal for fine finishing applications. This tube is a critical component of the gun's internal air passage system, directing compressed air from the air inlet through the gun body to the air cap. Proper air flow is essential for atomizing coating materials into a fine, consistent spray pattern.
The Maxum II service procedures detail the replacement of air tubes during maintenance of the check valve and valve seals. The tube connects to the check valve and air tube fittings, with specific orientation requirements to ensure proper air flow direction. A worn, cracked, or clogged tube disrupts air delivery, causing inconsistent spray patterns, poor atomization, and reduced transfer efficiency. Replacement with genuine 0277178 tube restores proper air flow and ensures reliable spray performance for professional finishing applications.
