3300PSI high-pressure pipe fittings with 1/4" internal bore, pressure resistance, heat resistance, corrosion resistance, aging resistance. Due to yellow zinc plated spring guards, are more corrosion resistant. With Minimal hose coil memory, easy to use during coiling and uncoiling. Softness, less deformed under high pressure. Light weight and flexibility, over 10% lighter weight and increased flexibility improve usability while spraying under pressure. Tight junction, no leak, corrosion resistant, suitable for all kinds of paints. Process upgrade, performance flexible, and abrasion-resistant. The tube body is tightly combined, soft in use, and less deformed under high pressure. Zinc-plated spring guards and polyurethane cover, all of these make this paint hose pressure-resistant, heat-resistant, wear-resistant. With the swivel female-nut the airless sprayer paint hose will be more flexible in use and reduce wear.
