$40.7The Graco 110037 Screw Mach Pnh is a precision manufactured fastener engineered to integrate with industrial pump heads in high-performance airless sprayer fluid delivery systems. Crafted from aerospace-grade 17-4 PH stainless steel and treated with an electropolished finish, this micro-sized screw delivers exceptional corrosion resistance and dimensional stability under dynamic loads. Its external thread geometry is cut to a tolerance of ±0.005 mm, ensuring interference-free engagement with matching internal threads in PNH pump manifolds. A specialized conical seat and integrated O-ring gland provide leak-tight sealing in applications requiring strict adherence to professional coatings and fluid purity specifications. Designed to withstand continuous operation at pressures up to 3000 psi, the Graco 110037 contributes directly to overall pump efficiency and the maximization of seal longevity, supporting maintenance intervals measured in thousands of operational hours. Compatible with a variety of high-pressure filtration modules, this precision fastener plays an essential role in maintaining consistent fluid shear rates and protecting sensitive downstream components. Once installed, its micro-fine finish and controlled thread pitch reduce galling and ensure stable preload under cyclic loading conditions. Its optimized stress distribution and consistent clamp preload enhance system performance under extreme duty cycles.
In advanced pump assemblies, the Graco 110037 Screw Mach Pnh serves as the primary interface between the drive end housing and the reciprocating plunger assembly. Its coarse 1.6 mm thread profile pairs with a 60° flank angle to optimize engagement strength while minimizing insertion torque, a critical factor when performing rapid field service on sprayer modules. Precision machining techniques, including CNC turning and grinding, yield a 0.3 μm surface roughness on both the thread root and crest, promoting consistent clamp loads and reducing micro-slip under pulsating flow conditions. The design accommodates high-pressure filtration attachments without requiring additional fastening hardware, streamlining assembly and reducing part count. Users integrating this screw into graco 395 sprayer applications benefit from reduced maintenance times and improved throughput in professional coatings workflows. Its compatibility with a wide range of seal materials—EPDM, FKM, PTFE—allows selection based on chemical compatibility and temperature requirements, ensuring performance in demanding environments ranging from chlorinated solvents to ultraviolet-cured lacquers. Overall, this fastener simplifies inventory and supports lean manufacturing initiatives.
Performance metrics derived from rigorous testing highlight the Graco 110037’s contribution to system reliability. Finite-element analysis confirms that its core cross-section maintains a safety factor of 3.2 under static tensile loads equivalent to 250 lb·in of torque, while fatigue analysis predicts service life exceeding one million loading cycles at 60 Hz reciprocation rates. Laboratory tests validate tensile strength values of 150 ksi and yield strength of 130 ksi, ensuring structural integrity under abrupt pressure spikes and vibration. Assembly torque recommendations center on 5 in·lb to achieve optimal preload without inducing thread deformation, preserving both pump efficiency and seal longevity. Field technicians report that replacement intervals for high-volume painting operations exceed 2000 hours, even when used in conjunction with high-viscosity media. When paired with accessories such as spray tips and hoses, including the versatile magnum x5 paint sprayer series, the Graco 110037 delivers consistent spray patterns and maintains fluid delivery rates within ±2% of nominal flow ratings, a critical parameter for precision finishing applications. Technicians frequently cite ease of installation and minimal recalibration downtime.
For integrators focused on maximizing uptime, the Graco 110037 Screw Mach Pnh is a proven solution within modular pump platforms such as PNH, P60, and HydraPak. Its small form factor—0.65 in long and 0.3 in in diameter—facilitates installation in confined pump end caps without compromising structural integrity or hydraulic sealing. The electropolished finish resists particulate adhesion, simplifying cleaning procedures and extending component life in abrasive media service. Maintenance best practices recommend periodic inspection for thread wear and O-ring compression set, using low-residue lubricants compatible with food-grade or solvent-based fluids as required. When applied in conjunction with the graco x7 airless paint sprayer, the screw ensures predictable performance in demanding commercial and industrial painting tasks. By maintaining tight control over thread tolerances and material hardness, Graco delivers a fastener that supports the rigorous demands of airless sprayer configurations and professional coatings processes, ensuring operators achieve uniform film build and optimal surface finish on every project. This precision screw underscores Graco’s commitment to engineered reliability and longevity. Select appropriate seal materials and lubricants to maximize service intervals and system cleanliness.
