Graco 286437 Standard Tip 437, 3-Pack - Aftermarket Replacement | Bedford 33-7437-3

Achieve steady coverage on heavy-bodied coatings with a standard (non-reversible) airless tip set engineered for production work. This aftermarket 3-pack replaces 286437 and is referenced by Bedford as 33-7437-3, providing an approximately 8″ fan with a 0.037″ orifice for high build passes when your sprayer and holder are configured for standard tips.

Aftermarket 0.037″ Orifice Standard Tip Holder

Why Choose This Standard Tip Set

  • Delivers an ~8″ fan with a 0.037″ orifice for thicker coatings and higher output.
  • Aftermarket cross verified for Bedford 33-7437-3 as a replacement for the OEM size.
  • Non-reversible “standard” style for sprayer setups using a conventional tip holder.

Service cue: Replace the tip when edges begin to tail or when pressure must be increased to maintain atomization - both indicate orifice wear.

Typical Compatibility

  • Standard (non-reversible) tip holders/guards used on compatible Graco airless guns.
  • Systems specifying “Standard Tip 437” in the IPL or selection guide (not for RAC 5/RAC X reversible guards).
  • Applications requiring narrow to mid fan with high build output on primers and protective coatings.

Verify your gun/guard style—standard tips do not install in RAC 5 or RAC X reversible guards.

What This Product Fits

  • Airless sprayers and guns equipped with a standard (non-reversible) tip holder that specify size 437.
  • Bedford aftermarket programs referencing Graco 286437; 33-7437-3 3-pack and 33-7437-10 10-pack.
  • Not for use with HandTite 243161 RAC 5 or RAC X guards - choose reversible tips for those systems.

Fan width varies with viscosity, pressure, and spray distance - confirm with a test pass before production.

Installation Notes

  1. Relieve sprayer pressure and lock the trigger per your manual.
  2. Confirm your holder is the standard, non-reversible type (not RAC 5/RAC X).
  3. Seat the 437 tip in the holder with the fan orientation as required; tighten securely.
  4. Start at low pressure and increase until the fan is even without heavy edges.
  5. Make a test pass on masking to verify pattern and overlap at your working distance. :

Tip: Keep a spare gasket/seal for the holder; replace at the first sign of weeping around the nut.

When to Rebuild / Replace

  • “Cat-ear” tails or streaks even after pressure tuning (orifice wear).
  • Need to raise pressure significantly to maintain atomization.
  • Fan narrowed from the labeled ~8″ due to erosion.
  • Persistent leaks at the holder indicating a worn/contaminated seat.

FAQs

Yes. It cross-references to the 437 standard (non-reversible) tip with matching fan/orifice output. :contentReference[oaicite:28]{index=28}
“4” ≈ 8″ fan (4×2), “37” = 0.037″ orifice; higher orifice numbers increase flow. :contentReference[oaicite:29]{index=29}
No. Standard tips fit standard holders only; RAC 5/RAC X require their respective reversible tips and guards. :contentReference[oaicite:30]{index=30}
Always stay within the sprayer/gun’s rated working pressure and tune only as high as needed for an even fan. :contentReference[oaicite:31]{index=31}
