Key Benefits

Consistent, fine-finish atomization for smooth results on trim and cabinetry.
0.018″ orifice balances control with productivity for many finish coatings.
Wide 16–18″ fan helps maintain even coverage on doors and panels.
Works with common Graco airless sprayers using standard 7/8″ guards.

Setup & Usage Notes

Start at lower pressure and increase only until a clean, even pattern is achieved.
Strain materials and maintain clean filters to reduce tip clogging.
Match hose ID and length to fine-finish flow needs; avoid excessive hose length when possible.
Use the correct tip guard (7/8″); older 11/16″ guns require an adapter or different guard.

Frequently Asked Questions

If your gun uses a 7/8″ (22 mm) tip guard and is rated for the operating pressure you intend to use, the Graco 163818 will fit. For older guns with 11/16″ guards, use the appropriate adapter or a compatible guard.

Fine-finish coatings such as lacquer, varnish, urethane, clear coats, and properly thinned enamels. Always test and adjust pressure for a clean, consistent fan.

Match orifice size to your coating viscosity and desired flow. The 0.018″ size offers a good balance for many trim and cabinet coatings; thicker materials may need a larger orifice, while very thin materials may atomize better with smaller sizes.

Keep materials filtered, relieve pressure before servicing, clean promptly after use, and store the tip dry. Replace worn tips to maintain pattern and finish quality.
