The Graco 188600 Union Swivel Fitting ensures seamless connections in heavy-duty spray applications. Designed for rugged performance, this fitting integrates effortlessly into any airless sprayer, optimizing fluid delivery with minimal downtime. Its precision-engineered swivel action reduces hose kinks and enables smooth hose rotation. Widely used in commercial and industrial settings, this union swivel fitting delivers long-term reliability while minimizing leakage and wear. It maintains consistent flow rates under demanding conditions and supports high-pressure filtration to protect your system.
Constructed from robust stainless steel and engineered for compatibility with professional coatings, the Graco 188600 offers unparalleled durability and leak-free operation. Quick-connect threads and standardized ports simplify integration into existing spray rigs, reducing setup time and maintenance complexity. Whether you work with latex, elastomeric, or solvent-based coatings, this swivel union delivers reliable performance, ensuring precise results and extended equipment life. Plus, a quick-connect design accelerates maintenance and replacement tasks, helping crews stay on schedule.
$135.63Whether you’re tackling large-scale industrial coatings or intricate automotive finishes, the Graco 188600 union swivel fitting delivers a leak-resistant, 360-degree rotational connection engineered for continuous operation. High-strength stainless steel construction stands up to chemical solvents and abrasive media, while precision-machined sealing faces ensure micrometer-level tolerances. Its union lock nut streamlines assembly and disassembly, reducing the need for specialized tools on busy job sites. This fitting is designed to maintain consistent fluid flow under variable pressure and temperature conditions, enhancing both reliability and performance.
Engineers opted for premium stainless steel alloys that resist corrosion, abrasion, and exposure to aggressive coating materials. Precision-ground sealing surfaces handle repeated engagement without compromising effectiveness. A low-friction bearing assembly inside the swivel reduces torque and extends service life during high-cycle applications. Union threads feature a private-design pitch that locks securely at the correct preload, preventing vibrational loosening and ensuring seal integrity across hundreds of switchover events.
Flow channels are contoured to minimize turbulence and pressure drop, preserving pump efficiency for flawless atomization. Polished bearing races decrease friction coefficients, resulting in longer maintenance intervals and a smoother hose feel for operators. Integration with high-performance sprayer platforms is seamless—particularly when paired with the graco 395 airless paint sprayer—so pressure consistency remains rock solid, even during rapid trigger pulls or extended spray runs.
Installation is simplified by an indexed union nut that clicks when proper engagement is achieved. A calibrated torque recommendation prevents over-compression of O-rings, while retaining ample sealing pressure. Routine maintenance requires only a standard wrench set and replacement O-rings, which can be swapped in minutes at the workbench. Seal faces and bearings benefit from periodic cleaning with compatible solvents to preserve original clearances and prevent premature wear.
Adaptable to a broad range of hose diameters, this swivel fitting uses readily available adapter sleeves for non-standard lines. It supports Graco’s QuickConnect couplings and integrates without additional clamps or brackets. In field trials, sprayers used with the graco 490 paint sprayer experienced fewer hose kinks and improved operator ergonomics, cutting downtime and enhancing overall coating quality.
By eliminating hose twist and torque build-up, the union swivel fitting reduces operator fatigue and enhances spray pattern consistency. Technicians regain valuable minutes otherwise spent untangling hoses, allowing them to focus on finish uniformity. When deployed on multi-gun rigs or robotic arms, this fitting’s 360-degree freedom contributes to faster cycle times and fewer stoppages—attributes exemplified in heavy-production environments using equipment such as the graco 695 paint sprayer.
Pressure rating: up to 6,000 psi (413 bar) Temperature range: -20°F to 200°F (-29°C to 93°C) Connection sizes: compatible with 1/4", 3/8", and 1/2" hose lines Material: stainless steel body, PTFE-backed O-rings Weight: 0.65 lb (0.29 kg) per fitting Cycle life: lab-tested to 10,000+ swivel rotations without seal degradation
Proven in shipyards, automotive plants, and industrial coating facilities, this union swivel fitting offers a blend of durability and precision few competitors can match. Its specialized thread design and hardened sealing faces minimize leaks, even under rapid pressure changes. Backed by Graco’s extensive technical support network, it delivers peace of mind on projects where downtime is unacceptable and finish quality must meet stringent standards.
