Graco H42550 High-Pressure Spray Hose

The Graco H42550 is a 50-foot high-pressure spray hose with a 1/4-inch inside diameter designed for professional painting applications. It handles a maximum working pressure of 4500 psi and features 1/4-inch fittings for secure connections. This hose suits contractors and serious DIYers who need reliable fluid delivery for airless spray systems.

Check sprayer compatibility and fitting requirements

Verify that your sprayer model appears in the supported list: X30DH4, X40DH4, X45DH4, X46DH4, X50DH4, X55DH4, X60DH4, X70DH4, X80DH4, or 287972. Confirm your system operates at or below 4500 psi and uses 1/4-inch fittings before ordering. Ensure the 50-foot length matches your job-site reach needs.

Replaces worn or damaged 1/4-inch airless hoses

Upgrade when your existing hose shows cover wear, fitting corrosion, or pressure loss that affects finish quality. The jump is worth it if you need the full 50-foot reach without couplers or if your current hose cannot hold 4500 psi. Not for low-pressure roller setups or sprayers requiring larger-bore hose.
