$49.97Precision handling in coatings delivery relies on properly engineered connectors like the Graco 189549 Fitting, Fluid QD. Engineered to facilitate uninterrupted fluid flow, this quick disconnect coupling offers a leak-free connection for high-pressure sprayers and industrial finishing equipment. A compact body crafted from hardened stainless steel resists corrosion and wear under demanding conditions. End users benefit from rapid setup and teardown cycles, which minimize downtime and streamline maintenance procedures.
Programmed for rugged environments, this fitting features precision-machined ports and a resilient polymer seal. Surface treatments exceed standard specifications, offering enhanced resistance to solvents and abrasive coatings. Performance-focused engineers often integrate this coupling with advanced fluid control modules, creating a robust fluid handling platform. Custom designs can include varied seal compounds to accommodate different chemicals and temperature ranges.
Operators frequently incorporate this accessory into their graco sprayer accessories inventory to ensure consistent performance across multiple jobs. Usage scenarios range from automotive painting booths to large-scale industrial coating lines. Quick-changeover capability lets crews switch between color sets in minutes, reducing material waste and maintaining tight production schedules. A reliable connection prevents drips during hose swaps, preserving finishing quality.
Integration with existing equipment often dictates retrofit requirements. Compatibility with other graco pump parts is seamless, thanks to precise thread tolerances and standardized port sizes. Fitting dimensions align with ISO and SAE standards, allowing synergies across different pump models and manifold assemblies. Facilities running multiple brands can count on this component to bridge connection gaps between legacy and modern systems.
Proper torque specifications guarantee seal integrity without damaging the thread profile. Apply a light film of compatible lubricant on the O-ring before engagement to prevent seal extrusion. When performing field installations, maintain cleanliness by using lint-free wipes and protective caps. Avoid overtightening; hand-tight flush followed by a quarter-turn with a calibrated wrench ensures reliable performance.
Routine inspection of sealing surfaces and valve mechanisms prolongs service intervals and prevents unexpected failures. Service technicians appreciate compatibility with a graco gun repair kit for on-the-spot repairs, eliminating lengthy downtimes. Spare parts packages include replacement O-rings, springs, and locking balls, designed to snap in without specialized tools. A preventive maintenance plan can be scheduled around production lulls to keep systems operating at peak efficiency.
Years of field experience underline its reliability under harsh conditions. Precision tolerances produce virtually zero bypass under pressure, preventing material loss and maintaining consistent spray patterns. Quick connect and disconnect operations dramatically simplify field servicing. Manufacturing processes adhere to ISO 9001 guidelines, ensuring each unit meets rigorous quality audits before dispatch.
Each coupling undergoes rigorous pressure cycling and leak testing to validate durability over millions of connect/disconnect operations. Flow curve analysis using calibrated test benches verifies minimal pressure drop across a range of fluid viscosities. Impact resistance trials simulate accidental drops, ensuring structural integrity remains intact. Chemical exposure protocols confirm compatibility with solvents, resins, and advanced coating materials. Quality control metrics document every batch, supporting traceability and compliance with industry best practices.
Operating pressure range spans from low to high extremes, supporting 0 to 3000 psi safely. Temperature tolerance extends from -20°C to +80°C, accommodating cold storage coatings and high-temperature coatings alike. Thread interface available in 1/4 NPT, M16x1.5 or custom sizes upon request. Seal materials include fluorocarbon, EPDM, and PTFE to match fluid chemistry. Overall length measures 45 mm, and weight remains under 80 grams for ease of handling in tight assemblies.
