The Graco 18H146 Kit, Ext Stain Project (311) is a professional-grade exterior staining accessory kit designed to improve reach, control, and finish quality when using Graco airless sprayers. It is commonly used for deck staining, fence coating, siding applications, and exterior wood finishing, where consistent spray pattern and extended mobility are required.
This kit typically includes a DuraFlex high-pressure hose extension, a 311 spray tip, and a spray extension wand, allowing users to spray difficult-to-reach areas without constantly repositioning the sprayer. The design focuses on reducing fatigue while maintaining a smooth, fine-finish spray pattern suitable for light to medium viscosity coatings such as stains and sealers.
A key advantage of the system is its compatibility with Graco’s airless platform, ensuring stable pressure delivery and reduced overspray when paired with the correct tip size. The included 311 spray tip is optimized for narrower spray patterns, making it ideal for controlled exterior stain application where precision matters more than coverage speed.
What is the Graco 18H146 Kit, Ext Stain Project (311)?
The Graco 18H146 Kit is an OEM exterior staining accessory package engineered for use with Graco airless paint sprayers. Its primary purpose is to extend the operator’s reach and improve spray control during exterior finishing projects. By integrating a flexible hose extension and a fine-finish 311 tip, the kit helps deliver consistent coating results on large surfaces such as fences, decks, and exterior trim.
It is designed specifically for staining applications rather than heavy latex painting, making it especially effective for penetrating stains and lighter protective coatings that require even, low-overspray application.

- Improved control: 311 tip provides a fine, consistent spray pattern for stain applications.
