$132.2The Graco 15K696 Cover Housing is a precision-engineered component integral to fluid management in high-performance coating pumps. Manufactured from hardened anodized aluminum, this cover housing ensures dimensional stability and resists structural deformation under cyclic pressure loads commonly encountered in industrial spraying. It interfaces directly with the pump manifold to maintain fluid alignment and containment, reducing turbulence and mitigating wear on internal components. The compact design, with an overall length of 3.35 inches and an optimized wall thickness, provides a balance between rigidity and weight savings for dynamic pump operation. Engineered to integrate seamlessly with Graco’s Pro and Xtreme series systems, it supports consistent spray patterns and reliable pressure thresholds. This component plays a critical role in extending pump service intervals within airless sprayer systems.
Material selection for the 15K696 Cover Housing centers on a 6061-T6 aluminum alloy substrate, chosen for its high yield strength and favorable thermal conductivity. The surface treatment employs a Type II anodization process to enhance abrasion resistance and inhibit chemical attack by solvents in aggressive coating formulations. Critical sealing interfaces accommodate EPDM and fluorocarbon O-ring variants, providing extended service life across a broad temperature range from –20 °F to 250 °F. Machined port geometries are optimized to reduce dead volume and prevent trapping of high-viscosity materials, while the integrated mounting flange features four standardized bolt holes for simplified field installation. These design strategies collectively support the requirements of modern professional coatings applications, minimizing maintenance downtime and ensuring consistent fluid delivery under demanding production cycles.
The 15K696 Cover Housing’s mechanical architecture is defined by rigorous finite element analysis (FEA) guidelines to validate structural integrity under pressures up to 3600 psi. Wall thickness distribution has been adjusted to counteract stress concentrations around bolt holes and fluid ports, resulting in uniform load distribution. Port interfaces exhibit a 45-degree chamfer for hassle-free O-ring seating and low-friction assembly, enhancing seal longevity and reducing cyclic stress on elastomeric components. The anodized finish not only improves corrosion resistance, but also provides a uniform surface energy conducive to solvent-laden coatings. Internally, flow channels are contoured to facilitate high-pressure filtration compatibility, accommodating inline filter elements that protect downstream pump internals from particulates and abrasive contaminants.
Performance testing of the 15K696 Cover Housing includes pressure cycling, flow calibration, and thermal profiling to determine operational limits and reliability margins. Data collected during continuous duty cycles indicate minimal pressure drop across the housing, preserving pump efficiency and reducing heat generation within the pumping chamber. Endurance tests exceeding one million reciprocation cycles demonstrate negligible dimensional drift, affirming the housing’s fatigue resistance under fluctuating load conditions. Compatibility with seal materials, such as nitrile and Viton, has been validated to deliver extended service life, achieving up to 5000 hours of leak-free operation. These metrics ensure that the cover housing supports high-throughput coating processes while maintaining consistent performance over prolonged periods.
Proper installation of the 15K696 Cover Housing requires adherence to specified torque values—typically 8 Nm for the mounting bolts—to avoid gasket extrusion or thread deformation. Prior to assembly, clean all mating surfaces to remove residual coatings or particulates that could compromise sealing surfaces or impede fluid flow. When replacing O-rings, apply a thin film of FDA-grade lubricant to minimize installation friction and prevent seal abrasion. Regular inspection intervals should coincide with pump maintenance cycles, with particular attention to any signs of corrosion or micro-cracks around stress points. The modular design simplifies disassembly, allowing technicians to swap cover housings in under 15 minutes, streamlining routine upkeep and troubleshooting in demanding production environments.
In industrial finishing operations, the 15K696 Cover Housing is a key component within Graco’s pump assemblies used for delivering high-viscosity epoxies, urethanes, and specialty fluoropolymers. Its robust construction reduces the risk of fluid leakage and contamination, enabling consistent application of sophisticated multi-component coatings. By preserving optimal flow path geometry and maintaining seal integrity, this housing aids in achieving uniform film thickness and defect-free surfaces on substrates ranging from automotive panels to heavy machinery. Integration with high-capacity filters and precision regulators enhances system uptime, while the durable housing design aligns with lean manufacturing objectives by minimizing part changeover times and unscheduled maintenance events.
