$11.02The Graco 119484 KEY Parallel Square alignment pin offers sub-micron positional accuracy for high-pressure fluid delivery equipment. With a height of 0.2 inches, length of 1.4 inches, and width of 0.2 inches, this compact component is crafted in the United States under strict ISO 9001 controls. Engineered to maintain pump efficiency and prolong seal longevity, it integrates seamlessly into airless sprayer modules where consistent fluid flow is critical. Its robust construction prevents torsional deformation during repeated service cycles, ensuring consistent alignment in reciprocating pump assemblies and precision manifolds. It also finds utility in hydraulic intensifier modules for enhanced fluid pressurization.
Crafted from a premium alloy substrate, the alignment pin undergoes CNC milling and electroless hard chroming to achieve surface hardness up to HRC 58. This process reduces friction at seal interfaces and supports high-pressure filtration of media in paint circulation loops. The component’s tolerance is held within ±0.001 inches, critical for automated multi-axis coating rigs. In applications requiring professional coatings on aerospace or automotive assemblies, this precision element minimizes runout and ensures repeatable performance across service intervals. The electroless chroming layer consistently measures 10 to 15 microns in thickness, conferring uniform corrosion protection.
The innovative PARALLEL design ensures uniform load distribution along the length of the pin, resisting bending under axial and radial forces encountered in piston pump chambers. Cross-sectional consistency is validated through coordinate measuring machine (CMM) analysis, confirming flatness and parallelism within microns. This design feature contributes to optimized pump efficiency, reducing energy consumption in continuous-duty spray operations. The geometry also facilitates straightforward insertion and extraction during maintenance, cutting downtime in high-output finishing lines.
Featuring a precision-machined SQUARE cross-section, this component achieves maximal surface contact with guiding bores, preventing tilt and ensuring concentric alignment. The squared profile enhances stability in high-vibration environments and supports seal longevity by minimizing extrusion gaps. High-pressure filtration systems benefit from reduced particle ingress when this pin maintains seal compression uniformly. Operators in industrial coatings plants rely on this durable alignment element to uphold product quality during continuous runs of solvent-based and waterborne finishes. This robust profile also aids in thermal stability during elevated temperature spray operations up to 80°C.
Tested to withstand pressures exceeding 5,000 psi, the Graco 119484 alignment pin remains dimensionally stable during burst tests and endurance trials. Its corrosion-resistant surface finish withstands aggressive media, including alkyd resins and epoxy dispersions found in professional coatings. Integration into high-pressure filtration assemblies enhances filter element life by maintaining optimal seal compression and reducing media bypass. As part of comprehensive fluid management, this pin plays a pivotal role in achieving repeatable spray fan patterns and consistent layer thickness in automated coating cells.
Designed for direct incorporation into Graco piston and diaphragm pump heads, the alignment pin supports seamless interchange with OEM manifolds. Its precise geometry aligns suction and discharge check valves, optimizing fluid transfer during each stroke. Maintenance teams appreciate the easy-to-grip form factor for swift replacement during scheduled services, ensuring minimal interruption of production. The pin’s compatibility extends to a range of spray reciprocators and rotary atomizers used in professional coatings, cementing its role in high-throughput finishing facilities. Integration guidelines available through technical bulletins detail torque specifications and material pairings for optimal performance under dynamic loading.
During installation, technicians align the pin with guide slots in the manifold plate, applying only minimal torque to eliminate play without overstressing the component. Routine inspections focus on surface wear and chroming integrity; a light polish can restore surface finish before limits are reached. In test laboratories, the alignment pin demonstrates exceptional fatigue resistance, maintaining dimensional fidelity after millions of cycles. Proper lubrication of surrounding seals augments seal longevity, while strict adherence to grit-free assembly extends overall service life in demanding environments.
Overall, the Graco 119484 Key Parallel Square alignment pin epitomizes engineering excellence for demanding fluid control and spray applications. Its precisely controlled dimensions, durable alloy construction, and optimized geometric profile enhance pump efficiency and reinforce seal longevity. Critical in airless sprayer modules and high-pressure filtration assemblies, this alignment element ensures consistent performance in professional coatings operations. By maintaining exact positional alignment, it safeguards equipment reliability and promotes repeatable, high-quality finishing outcomes across industrial manufacturing processes.
