The Graco TrueCoat 360 DSP is model 16Y386 — "DSP" stands for Dual Speed Premium. It runs a dual-speed pressure range of 900-1500 PSI at 120V, using a 0.015" tip, and shares its core pump and parts list with the standard TrueCoat 360 (16Y385) and the DS variant (17A466). The main functional difference is the DSP's dual-speed control, letting the user pick a lower setting for finer control or the higher end for faster coverage.
"Graco 360 DSP" refers to a specific model within the TrueCoat 360 handheld sprayer family — not a separate product line. This reference covers exactly what sets the DSP apart, its official specs, and the genuine parts that keep it running.
1. What "DSP" Actually Means
DSP stands for Dual Speed Premium. Where the base TrueCoat 360 runs at a fixed 1500 PSI, the DSP variant offers a dual-speed range, letting the operator choose a lower-pressure setting for finer control on detail work or the higher end of the range for faster coverage on larger surfaces.

3. The Three-Model TrueCoat 360 Family
16Y385 — TrueCoat 360
The standard, base-tier model in the family, running a fixed pressure output.
16Y386 — TrueCoat 360 DSP
The Dual Speed Premium variant covered in this guide — 900-1500 PSI dual-speed range.
17A466 — TrueCoat 360 DS
A related Dual Speed variant, sharing the same core parts list as the other two.
All three models share the vast majority of their parts list — pump components, tips, and reciprocator assembly are common across the family, which is why sprayersandparts.com lists all three model numbers together on a single parts page.
4. Genuine Replacement Parts
| Part | Part Number | Notes |
|---|---|---|
| Spray Tips | 17A223 | Black (12-in pattern) and gray (4-in pattern) options, shared across all three models |
| Wobble Reciprocator Assembly | 16X880 | Keeps internal components moving properly for consistent pressure |
| Dual Speed Control Switch | 16X868 | Specific to the DSP's dual-speed functionality |
| Sealing Plug | 16X869 | Closes unused fluid ports |
| Pump Armor (32 oz) | 243104 | Storage fluid, not shipped with the sprayer — sold separately |
The dual speed control switch (16X868) is the component most specific to the DSP's identity — it's what enables the dual-speed function that separates this model from the standard 360. Most everything else on this list crosses over cleanly to the 16Y385 and 17A466 variants.
5. What It's Built For
Like the rest of the TrueCoat 360 family, the DSP is a cup-fed handheld sprayer — no suction tube, no bucket, just a 32-oz cup that attaches directly to the unit. It's built for DIY projects across doors, interior walls, trim, fences, garage doors, and indoor or outdoor furniture, with the dual-speed control giving slightly more flexibility across that range of project types than the fixed-pressure base model.
