Graco XHD537 Airless Spray Gun Tip .037 in

Graco XHD537 Spray Tip 0.037 In

The Graco XHD537 is an airless spray gun tip with a 0.037 inch orifice designed for professional coating applications. It produces a reversible fan pattern between 10 and 12 inches wide. The tip connects via a 7/8 inch thread and is rated for a maximum working pressure of 7,250 psi. It is intended for painters and contractors using compatible Graco spray equipment.

Practical Pressure and Pattern Limits

The tip operates up to 7,250 psi, making it suitable for high-pressure airless systems handling thicker materials. The reversible feature allows quick clearing of clogs without removing the tip from the gun. The fixed 10 to 12 inch pattern width limits its use on very narrow trim or extremely broad surfaces where a different tip size would be required. It is compatible only with specific Graco guard and housing models listed by the manufacturer.

Installation and Common Issues

Installation requires threading the tip onto a compatible 7/8 inch guard or housing such as the 288022 or X30DH4 through X80DH4 series. Ensure the seating surface is clean to prevent leaks at high pressure. A common issue is using the tip with an incompatible guard, which can cause misalignment or pressure failure. Reversing the tip regularly during spraying reduces tip wear and prevents dried material from blocking the orifice.
