Compatible with a range of spray guns, it maintains optimal pressure and supports effective professional coatings delivery. Perfect for automotive, industrial, and architectural projects requiring high-pressure filtration. Crafted from corrosion-resistant brass, this fitting withstands harsh solvents. Its universal fit works with both solvent- and water-based materials, ensuring reliable atomization across a variety of professional coatings.
$14.28Graco 17N459 Barbed Exhaust Air HVLP Fitting delivers an engineered solution tailored to elevate airflow management within high-volume, low-pressure spray systems. Built to ensure a tight seal on pneumatic exhaust ports, this barbed adapter helps maintain consistent pressure and reduces turbulence, preventing overspray and optimizing coating patterns for professional results.
Precision machining creates a uniform bore with smooth radii that vastly reduce eddy currents and pressure loss. Computational fluid dynamics (CFD) analysis confirms that this fitting maintains laminar flow up to 320 scfm at 80 psi inlet in standard 10-foot tubing. External contours are deburred and polished, while internal surfaces undergo passivation to remove residual iron particles and ensure a contamination-free pathway for solvent-laden or particulate-filled coatings.
Assembly requires simple hand tools and minimal training. Cut hoses squarely and slide them fully onto the widest barb ridge before securing with a recommended clamp or crimp sleeve. Integrated thread reliefs and sealing grooves accept PTFE tape or anaerobic sealants, eliminating leaks without additional adapters. A slight chamfer at the barb entrance guides each tube into place, making installation rapid and foolproof even under production pressures.
Machined from hardened stainless steel alloy, this fitting resists chemical attack in solvent-rich atmospheres and remains dimensionally stable under thermal cycling. Electropolishing removes micro-asperities, reducing surface stress concentrations and warding off corrosion. Exterior plating further shields against impact and environmental contamination, ensuring the adapter retains original tolerances throughout extended service intervals in automotive, aerospace, or wood finishing facilities.
Independent flow bench testing shows negligible pressure drop—less than 0.5 psi—across the fitting at typical HVLP system rates. When used with ¼" ID polyurethane tubing, it enables consistent atomization even with high-viscosity coatings. Fatigue tests exceeding 10,000 install-remove cycles reveal no measurable loss of barb retention force. Such reliable metrics translate to uniform spray deposition and reduced downtime, crucial for large-scale production lines and mobile spray rigs.
Designed for direct integration with most HVLP manifolds, spray guns, and fluid reservoirs, this adapter allows operators to replace worn exhaust fittings quickly. Routine inspections should focus on barb integrity; any signs of microcracking or deformation warrant immediate swap-out. When servicing fluid circuits in parallel, technicians often couple this component with a graco paint sprayer pump repair kit to rejuvenate pumps, valves, and seals, preserving peak performance.
Modularity extends to pressure regulators, fluid filters, and manifold blocks that mount around the exhaust port. By sourcing genuine graco replacement parts, you ensure dimensional consistency and compatibility with OEM specifications. This approach prevents mismatched tolerances, preserves warranty coverage, and streamlines inventory management. Whether retrofitting existing spray booths or configuring new portable stations, these adapters slot seamlessly into multi-outlet distribution plates.
Exhaust port diameters and barb sizes are matched to the graco magnum paint sprayer platform, allowing universal drop-in use without additional couplers. System integrators appreciate that hose IDs, barb pitches, and thread forms all align with popular air supply modules. This ensures that performance tuning—be it for automotive refinishing or industrial powder coatings—remains consistent and predictable across multiple sprayer models.
Rated for operating temperatures from –20 °C to 120 °C, this fitting functions reliably in cold storage warehouses and adjacent to curing ovens. OEM-approved sealing compounds maintain barrier integrity in solvent-rich environments, preventing leaks or pressure loss. For comprehensive upkeep, scheduling inspections alongside HVLP service kits reinforces uptime and quality control. Experts recommend incorporating the 17N459 exhaust air fitting into routine maintenance plans to sustain optimal spray performance and facility safety.
