$242.79The Graco 162265 inlet adapter is engineered to facilitate robust coupling between fluid delivery systems in airless sprayer applications. Designed with a 3/8"-18 NPSM (M) inlet and a 1/4"-18 NPT (F) outlet, this precision component ensures optimal flow dynamics and minimal turbulence during high-volume coating operations. Its geometry is optimized to maintain laminar flow characteristics under continuous-duty cycles, thereby reducing pressure drop and ensuring consistent output from downstream pump assemblies.
Constructed from a corrosion-resistant stainless steel grade, the body of the adapter exhibits exceptional durability against abrasive particulates and chemical solvents used in professional coatings. The choice of 17-4 PH stainless steel provides a balance of hardness and corrosion resistance, while the finish is passivated to inhibit oxidation. Precision machining and surface treatment processes yield consistent thread tolerances, ensuring leak-free performance and extended component life. This assembly corresponds to part number 162265 and meets industry standards for fluid delivery couplings in high-pressure systems.
Performance testing under controlled conditions indicates a negligible flow restriction, with measured pressure drop below 2% at typical sprayer flow rates. The adapter supports pump efficiency enhancements by reducing recirculation losses and maintaining stable operating pressures. Its compatibility with advanced high-pressure filtration systems allows for uninterrupted filtration of particulate-laden fluids, preserving nozzle integrity and ensuring uniform spray patterns. Seal longevity is maximized through the use of precision-ground O-ring grooves that accommodate high-temperature elastomers without extrusion or degradation.
The design employs a hexagonal body with optimized wrench flats, facilitating rapid installation and precise torque application. Finite element analysis (FEA) was applied to validate stress distribution under peak load conditions, confirming a safety factor of 1.8 above rated pressure. Thread runout and lead angle are controlled to ANSI specifications, preventing cross-threading and enhancing repeatability during assembly. Internal flow passages are chamfered to reduce eddy formation, contributing to consistent fluid delivery rates even under variable supply conditions.
In airless sprayer rigs for architectural finishes and industrial coatings, the Adapter Inlet is pivotal for maintaining uninterrupted fluid delivery. Its compatibility with standard pump manifolds and hose assemblies enables streamlined system integration. When used with professional coatings including epoxy, urethane, and latex dispersions, it supports consistent atomization and finish quality. Optimal torque settings and periodic inspection protocols are recommended to sustain seal integrity and extend service intervals on high-pressure filtration units.
Installation requires careful alignment of male and female threads, followed by a calibrated torque of 25–30 ft·lb to ensure a reliable seal without compromising thread integrity. Thread sealants rated for high-pressure hydraulic fluids may be applied sparingly to augment sealing performance. Routine maintenance includes verification of torque settings and inspection of elastomeric seals for signs of wear or hardening under cyclic thermal loads.
Compatibility spans a range of Graco and OEM pump models, including piston and diaphragm configurations. The adapter’s flow path geometry is optimized for minimal pressure loss, enhancing pump efficiency and reducing energy consumption in continuous operation. Fluid dynamic simulations confirm uniform velocity profiles, minimizing cavitation risk at the inlet port.
Overall, the Graco 162265 inlet adapter represents a finely tuned component in high-pressure fluid delivery systems, balancing mechanical resilience, corrosion resistance, and precision flow control. Its engineered features support reliable operation in demanding industrial environments while contributing to enhanced pump efficiency and seal longevity across service cycles.
Periodic in-situ analysis of thread wear and seal compression must be incorporated into preventive maintenance schedules to ensure consistent performance. Using borescope inspection tools, technicians can verify internal passage integrity and detect early signs of fatigue or micro-cracking. Replacement of elastomeric seals should follow manufacturer-recommended intervals based on operating temperature cycles and chemical exposure. When integrating high-pressure filtration cartridges, ensure that upstream pressure relief valves are calibrated to protect the adapter from transient spikes. Proper storage and handling procedures, including corrosion inhibitors and dry nitrogen purge, extend service life. Lifecycle modeling predicts over 50,000 actuations before requiring major overhaul, demonstrating long-term cost-effective reliability in demanding spray systems.
