Graco RAC X 521 Reversible Spray Tip – For Airless Application of Roof Coatings

The recommended spray tip for fast, professional application of Noxseal and Pro Rust coatings.

The Graco RAC X 521 reversible tip is the industry-standard nozzle for airless sprayer application of elastomeric roof coatings. Specifically recommended for use with Noxseal and Pro Rust products, this tip delivers the ideal spray pattern and flow rate for even, consistent coverage on metal roofs, flat roofs, and shingle surfaces.

Its reversible design allows you to quickly clear clogs on the job — just twist the tip 180° and spray to flush, then twist back and keep working. No downtime, no tools needed.

Key Features

  • Reversible design — clear clogs instantly by rotating the tip 180°. No disassembly needed
  • 521 pattern — 10-inch fan width at 12 inches from the surface, ideal for roof coating applications
  • Compatible with all Graco RAC X airless sprayers
  • Specifically recommended for Noxseal and Pro Rust elastomeric coatings
  • Professional-grade — the same tip used by commercial roofing contractors

Recommended Pairing

  • Noxseal — use tip 521 or 523 for optimal coverage (~350 sq. ft. per 5-gallon pail)
  • Pro Rust — use tip 521 or 524 for optimal coverage (~350 sq. ft. per 5-gallon pail)

What's in the Box

  • 1x Graco RAC X 521 Reversible Spray Tip

Pro Tip

If you're coating a large roof with an airless sprayer, keep a spare 521 tip on hand. Tips wear over time and a worn tip means uneven coverage. Swapping in a fresh tip halfway through a big job ensures consistent results from start to finish.
