The Graco 17M822 adapter is precisely engineered for airless sprayer systems, providing seamless connections between spray guns and fluid outlets. This accessory is favored in professional coatings projects for its precise control and high durability. Tailored for both solvent- and water-based finishes, it offers exceptional resistance to wear, corrosion, and abrasive media. Designed to withstand rigorous cycles, the 17M822 ensures long-term service life even when used with high-pressure filtration units, delivering peak spray performance across diverse industrial and commercial projects.
When paired with the matching nut, this adapter delivers leak-proof performance. Its compact design supports fast assembly and cleanup, making it a must-have accessory for contractors, painters, and specialists tackling large-scale projects where reliability and efficiency are paramount. Its leak-resistant seal design prevents loss of coating material and reduces cleanup time, enhancing productivity. Quick twist-lock installation ensures fast setup so professionals can focus on application quality without interruption.
Graco 17M822 Adapter Nut is a precision-engineered connector designed to enhance the reliability and longevity of industrial paint sprayers. Crafted to interface seamlessly with Graco’s modular spray assemblies, this component delivers a secure, leak-resistant bond between the main body and attachment lines. By maintaining a tight seal under high pressure and resisting corrosion over extended use, it ensures uninterrupted performance for professional operators. Whether used in automotive refinishing, wood finishing, or large-scale architectural coatings, this adapter nut stands as an essential element in any maintenance toolkit.
At the heart of the 17M822 design, CNC-machining delivers tolerances within microns, ensuring concentricity and balanced pressure distribution. Certified to ISO 9001 quality standards, each nut boasts a minimum yield strength of 500 MPa, guaranteeing structural resilience under repeated cyclic loads. Surface treatments include passivation and electropolishing to reduce roughness, minimizing particle adhesion and facilitating quick cleaning in workshop environments. Laboratory testing under elevated temperatures confirms that the nut retains structural integrity up to 200 °C, making it suitable for solvent-based coatings and high-viscosity materials. Integration of robust alloys further enhances fatigue resistance, reducing the likelihood of thread wear after repeated assembly cycles.
Compatibility across the Graco ecosystem is central to this adapter’s utility. It interfaces directly with feed lines, pump outlets, and manifold assemblies without requiring additional couplings or adapters. Models such as Ultra Max, Airless Sprayer 695, and Xtreme series benefit from this connector, which also adapts well to pressure washers used in surface prep. To maintain optimal flow rates and avoid pressure drops, proper sizing is critical, and this nut accommodates diameters ranging from 1/4" to 3/8". Aligning precisely with internal O-rings and seals, it prevents leaks even under 3000 psi. To get the best results, ensure regular replacement of graco paint sprayer filters.
Installation follows a straightforward five-step procedure: thread the nut by hand, seat firmly against mating surfaces, apply recommended torque using a calibrated wrench (typically 80–100 in-lb), perform a pressure-hold test, and inspect for seepage or misalignment. Applying a compatible silicone-based thread sealant prevents galling and further enhances sealing efficiency. Always lubricate threads with a compatible grease to facilitate future disassembly, and ensure O-ring grooves are free of debris. Periodic torque checks are advised, especially after initial startup or thermal cycling. Also compatible with graco paint sprayer hoses in your network, this component simplifies maintenance workflows and reduces downtime.
In high-pressure spraying operations, even minor leaks can lead to performance losses and safety hazards. Symmetrical design reduces turbulence and pressure pulsations, leading to smoother spray fan patterns and improved edge definition. By employing a flawless seal, the 17M822 adapter nut preserves constant downstream pressure, ensuring consistent atomization and finish quality. Endurance trials simulating 10,000 cycles produce no detectable wear on thread faces or bearing surfaces. Pulse-damping effects also help moderate pressure spikes, contributing to smoother spraying and reduced operator fatigue. These characteristics make it a trusted choice for heavy-duty applications like industrial coating lines or marine refinish bays.
Routine checks of the adapter nut’s seal integrity should be part of any preventive maintenance schedule. Inspect the interface for minimal radial play and look for signs of O-ring extrusion or surface wear. After roughly 500 operational hours, O-rings and seals should be replaced and the nut can be cleaned in ultrasonic baths to preserve surface finish and prevent residue buildup. When replacement becomes necessary, the component can be swapped without dismantling primary pump assemblies, saving valuable production time. Alongside genuine spray tips, extensions, and graco paint sprayer gun parts, this adapter nut simplifies inventory management and ensures consistent compatibility with legacy systems. This focus on quick-turn service underscores Graco’s commitment to uptime and customer satisfaction.
Incorporating the Graco 17M822 Adapter Nut into your sprayer maintenance regimen boosts operational reliability and reduces the risk of fluid leaks. Its precision fit, corrosion-resistant alloys, and pressure-holding capacity make it a must-have accessory for any professional coaters or equipment service teams. By pairing this component with other genuine accessories, you can maintain peak performance, extend service intervals, and uphold quality control standards. Encourage technicians to include this adapter nut in all routine inspections. Trust this adapter nut to deliver consistent results in demanding environments, supporting your high-quality spraying processes and overall equipment longevity within your maintenance program. With factory-backed technical support and comprehensive documentation, integrating this adapter nut into existing workflows becomes seamless. Field technicians will appreciate detailed service manuals and training resources. A single purchase decision can optimize productivity and safeguard finish quality across multiple job sites.
