The Graco 17X020 PinSpringClevisLower is a precision-engineered component designed to enhance the performance of your coating and spraying systems. Essential for any professional painting contractor or industrial applicator, this durable clevis lower pin spring assembly delivers consistent alignment and secure attachment to spray guns, improving operational stability and reducing downtime. Engineered to integrate seamlessly with modern airless sprayer setups, it provides reliable functionality under high-pressure conditions. Manufactured from hardened stainless steel, the component withstands abrasive materials and corrosive fluids, ensuring long-lasting service life. Its innovative design combines smooth actuation with precise calibration to optimize spray patterns and maintain uniform coverage. By incorporating the Graco 17X020 PinSpringClevisLower into your maintenance program, you benefit from peak equipment efficiency and minimized service interruptions, while maintaining the necessary high-pressure filtration standards. Whether working with solvent-based or water-based formulations, this part supports superior flow control and delivers consistently high-quality results with professional coatings applications.
Graco 17X020 PinSpringClevisLower serves as a vital pivot component inside advanced airless spray valves, translating spring tension into smooth, repeatable nozzle control. Engineered from hardened stainless steel, this linkage tolerates significant shear stresses and repetitive cycles without fatigue. Sprays demanding consistent atomization depend on every internal juncture, and a subpar clevis can introduce lag, drips or uneven coverage. Graco’s strict machining tolerances ensure that each part aligns perfectly with adjacent assemblies, reducing wear and preserving sealing integrity. Operators benefit from an optimized stroke response, minimal downtime and service intervals extended through corrosion-resistant finishes and precision grinding.
Modern finishing applications place greater demands on metallurgy and component geometry. PinSpringClevisLower features a proprietary heat treatment that boosts core hardness without sacrificing ductility. Microstructural control during quenching and tempering eliminates internal stress risers. Dimensional inspections at every stage maintain tolerances within microns, ensuring concentricity around the pivot axis. This attention to microscopic detail minimizes vibration and oscillation, which can degrade paint quality. Whether handling viscous coatings or fast-drying lacquers, this clevis link adapts to variations in pressure, temperature and chemical exposure thanks to its multi-phase alloy formulation.
In high-pressure operations, even minor misalignments create exponential increases in friction and wear. PinSpringClevisLower addresses this by combining a self-lubricating surface finish with a chamfered end geometry that guides actuator pins smoothly into place. Load distribution remains uniform across the contact face, reducing point stresses that lead to galling. Field tests reveal stable valve actuation beyond 3,000 psi, with cycle life outperforming generic alternatives by up to 25 percent. Advanced dynamic testing simulates real-world spray patterns, confirming that oscillatory and reciprocating stresses are evenly absorbed without compromising valve seat integrity.
Integration into legacy and current systems ranks among the clevis’s strongest attributes. Retrofit kits allow drop-in replacement for models dating back over a decade. Detailed compatibility charts cover a broad range of sprayers, including the graco x7 airless paint sprayer. Adaptors or minor bracket modifications enable seamless installation on both small- and large-frame assemblies. Clear machining marks indicate orientation, preventing misassembly and avoiding downtime. Calibration remains straightforward, with minimal adjustments to spring preload and linkage travel as outlined in service bulletins.
Maintenance crews appreciate a design that simplifies disassembly and reassembly. Fast access to the clevis area shortens repair procedures to a few minutes, with no specialized jigs required. Guide pins and retaining clips are intentionally oversize for tool engagement, eliminating fumbling in confined housings. Comprehensive instructions accompany every unit, showing torque specs and lubrication points. Unlike one-piece assemblies, a modular clevis design enables replacement of individual components rather than an entire valve block. Technicians working on a graco 395 paint sprayer can leverage familiar workflows and reduce service time.
Routine inspections hinge on visual checks and verifying actuation force curves. Wear patterns should be symmetrical; any lateral scoring indicates misalignment upstream. When in doubt, refer to the graco 395 parts diagram to confirm correct part orientation and order of assembly. Periodic ultrasonic cleaning removes micro-debris that can accumulate between crevices. A light coat of specialty grease maintains low friction and prevents moisture ingress. By following a regular maintenance schedule, users extend valve life by hundreds of hours, minimizing unexpected shutdowns during critical projects.
For professionals seeking reliable finishing results, Graco 17X020 PinSpringClevisLower represents a granular upgrade that pays dividends in uptime and coating uniformity. Backed by expert technical support and a full range of replacement kits, this linkage component meets the demands of industrial, commercial and contractor-grade services.
