The Graco 113848 Flange is a rugged polypropylene component designed to seamlessly integrate with your 1590 Poly pump system. Engineered for demanding projects, this flange supports high-pressure filtration to deliver consistent output and optimal flow rates for professional results. Whether you’re applying thick industrial coatings or delicate finishes, this accessory maintains stable pressure across your airless sprayer, minimizing downtime and ensuring uniform coverage. Perfect for users of the spray paint gun graco lineup, the flange’s precision fit reduces leaks and extends equipment life. Built with corrosion-resistant materials and easy-to-clean surfaces, it’s the go-to choice for heavy-duty operations where reliability and performance are paramount. Its ergonomic design ensures seamless attachment to your graco paint sprayer, making it an indispensable accessory for finishing tasks.
The Graco 113848 flange is a precision-engineered interface module designed to optimize fluid delivery in high-performance airless sprayer configurations. Manufactured from injection-molded polypropylene, this component provides chemical inertness and robust mechanical integrity under continuous load cycles. It serves as the critical junction between the fluid pump assembly and downstream manifold, ensuring uniform pressure distribution and seamless integration with professional coatings formulations. Advanced design features such as a 1.5-inch port diameter and standardized bolt pattern facilitate modular assembly and simplify retrofitting in legacy pump systems. Users integrating with modern plasma-hardened pistons and membrane separators will appreciate its impact on noise reduction and flow stability when operating in demanding industrial or commercial environments. Experience enhanced fluid control with graco sprayers compatibility.
Geometric precision in the flange design is achieved through CAD-driven modeling and finite element analysis to withstand pressures up to 5,000 psi. The profile includes a recessed gasket groove compatible with 113855 elastomer seals, promoting seal longevity and facilitating rapid replacement. High-pressure filtration cartridges can be installed upstream of the flange to safeguard against particulate ingress, enhancing pump efficiency by maintaining optimal clearance tolerances. The standard flange thickness of 6 mm ensures minimal deformation, while radial stiffening ribs dissipate stress concentrations during thermal cycling. Fastener engagement points align with Graco’s bolt-down kits, streamlining assembly and reducing installation torque variation across multi-station spraying lines.
Composed of high-density polypropylene, the 113848 flange exhibits exceptional resistance to solvents and acids common in automotive and architectural coatings. Material selection is driven by dimensional stability and low moisture uptake to maintain tight tolerances under fluctuating temperature conditions. The flange mating surface features a 30-degree chamfer to guide gasket placement without jeopardizing the interface seal. We also recommend pairing with PVDF variants in corrosive media or employing PTFE gaskets for abrasive slurry applications. Integration with Graco’s latest pump heads, including the graco 360 dsp, leverages this flange’s robust seal retention for uninterrupted application of epoxy, urethane, and silicone-based professional coatings.
Testing under lab conditions indicates that the polypropylene flange maintains structural integrity at cyclic pressures between 500 psi and 4,000 psi with negligible creep. Flow characterization shows linear throughput beyond 2 gallons per minute at maximum outlet pressure, ensuring uniform film thickness in large-scale spraying setups. Compatibility trials with the x7 paint sprayer confirmed minimal pressure drop across the interface, preserving pump stroke rate consistency. Long-term durability assessments reveal over 100,000 actuation cycles without seal compromise, validating exceptional seal longevity. When combined with supplemental high-pressure filtration modules, the 113848 flange supports contamination thresholds below 5 microns, critical for void-free finishes in commercial and industrial applications.
Proper installation of the 113848 flange begins by verifying gasket integrity and aligning the bolt pattern to prevent cross-threading. Recommended torque values range from 15 to 20 ft-lb per 1/4-inch fastener, ensuring uniform compression without overstressing the polypropylene body. Routine maintenance protocols call for quarterly inspections under high-cycle usage, focusing on potential stress lines and microfractures in the flange webbing. Seal replacement intervals typically coincide with pump overhaul schedules, although visual checks of wear patterns can extend service life. Airless sprayer operators should purge residual coatings before disassembly to mitigate solvent attack, and realign mounting surfaces within 0.02 inches to maintain optimal pump efficiency.
In versatile spray systems, the 113848 flange acts as a seamless upgrade for both legacy manifolds and state-of-the-art pump modules. Its inert polypropylene composition minimizes galvanic potential when paired with stainless steel, enhancing corrosion resistance in humid environments. Compatible with variable frequency drives and digital pressure sensors, it enables real-time monitoring of flow rates and system health. This integration supports precise pressure control during start-up sequences to limit overshoot and material waste. The flange’s adaptability to portable and stationary rigs promotes consistent finish quality across diverse industrial coatings applications.
As an engineered interface, the Graco 113848 polypropylene flange exemplifies the materials science and precision manufacturing powering modern airless sprayer assemblies. Optimizing fluid passage and pressure integrity, it elevates system reliability in professional coatings projects. Strict maintenance schedules, correct gasket selection, and proper torque application ensure extended service life and uninterrupted throughput. Deployed in automotive refinish bays, architectural painting rigs, or specialty coating lines, this flange improves metrics such as pump efficiency and particulate control. Thorough integration and proactive inspection enable operators to maximize equipment potential while minimizing downtime and achieving superior finish consistency.
