Overview & Key Details for Graco 163871 Silver Flat Tip, 871
The Graco 163871 is a legacy Silver Flat Tip (871) for airless spraying. It delivers a wide, flat fan for high-output work. Always verify your sprayer’s maximum tip size/orifice and guard/thread compatibility before use.
Compatible Machines (verify max tip size in your manual)
Technicians typically pair large-orifice flat tips like the 163871 with high-output, gas/hydraulic rigs used for heavy coatings.

At-a-Glance Specifications
| Tip Family | Silver Flat Tip (legacy flat/non-reversible style) |
| Part Number | 163871 |
| Stamp / Size Code | 871 |
| Orifice Size | 0.071 in. (large-output) |
| Approx. Fan Width* | 16–18 in. at ~12 in. from surface (*depends on pressure, coating, distance) |
| Max Working Pressure | Up to 5,000 psi (tip rating; follow sprayer/gun/hose ratings) |
| Mount / Thread | Fits guards using the legacy 7/8"-16 tip thread (confirm your guard type) |
| Best For | High-production passes on large flat areas; heavy-bodied coatings (e.g., elastomerics, block-filler) where a wide fan and high flow are desired |
Why Choose the 163871 Tip
- Wide Coverage: 16–18" fan pattern for fast production on big surfaces.
- High Flow: 0.071" orifice handles heavy coatings when paired with suitable rigs.
- Durable Legacy Design: Silver Flat Tip geometry known for consistent, flat spray pattern.
Important Usage Notes
- Confirm your sprayer’s maximum tip/orifice rating; do not exceed manufacturer limits.
- Match the guard/thread style (legacy Silver Flat vs. RAC systems).
- Use appropriate filters and maintain clean material to reduce pattern defects.
- Start at the lowest effective pressure and adjust just enough to fully atomize the coating.
Frequently Asked Questions
It fits guards that accept the legacy Silver Flat tips (typically 7/8"-16 thread). You must also confirm your sprayer’s maximum tip size/orifice supports 0.071". Many smaller sprayers do not support this size.
High-build or heavy-bodied materials (e.g., elastomerics, block-filler, certain primers) applied with high-output rigs on large, open surfaces. Always follow coating manufacturer recommendations for tip sizes and mesh filtration.
Approximately 16–18" when held ~12" from the surface, depending on pressure, viscosity, and technique. Adjust pressure just enough to achieve full atomization.
Generally no. The 0.071" orifice demands high flow and pressure output. Using it on undersized units can cause poor atomization, pressure drop, or equipment damage.
