$209The Graco 114477 Tube Flare Riser Tube SST is engineered from 316 stainless steel to deliver uncompromised mechanical integrity and corrosion resistance in demanding fluid systems. Its single-flare design adapts to high-pressure lines with smooth interior surfaces and minimal dead volume, enabling consistent flow profiles and reduced particulate entrapment. The precision-welded riser segment maintains structural rigidity under cyclic stress while preserving geometric tolerances crucial for seal longevity. Designed for precise wall thickness control and enhanced temperature cycling resilience, it meets rigorous fluid safety standards. With a meticulously polished finish, this riser tube resists abrasive wear and chemical attack, ensuring long-term reliability. Integration into modular manifold assemblies or direct coupling with spray guns is achieved through standardized flare fittings that mate seamlessly with both Graco and industry-standard connectors. The streamlined internal path optimizes fluid acceleration in an airless sprayer environment, supporting stable output even at elevated operating pressures.
The Graco 114477 tube exhibits a rated working pressure up to 3600 psi, verified through hydrostatic testing protocols that align with ASTM guidelines. Batch traceability is ensured through laser etching of unique identifiers. Computational fluid dynamics simulations demonstrate uniform velocity distribution and minimal turbulence at flow rates up to 9 gpm, maximizing pump efficiency by reducing pressure drops across transitions. Thermal expansion coefficients for the 316 SST alloy are accounted for in design clearances, preventing material fatigue and ensuring consistent performance across temperature ranges from –20 °C to 80 °C. Surface finish (Ra ≤ 0.4 µm) combined with proper flare seating reduces load on PTFE or HNBR seals, extending system maintenance intervals for professional coatings applications and ensuring enhanced seal longevity. Precise nominal bore dimensions uphold laminar conditions critical for atomization systems and maintain compatibility with high-viscosity primers, urethanes, and epoxies.
The modular architecture of the Graco 114477 riser tube simplifies integration within centralized fluid distribution networks, especially in applications requiring multi-stage pumping and provision of inline filtration modules. Its geometry accommodates quick-connect valves, high-pressure filters, and pressure transducers without inducing deadheads or flow restrictions. When paired with cartridge-type or sintered metal filter elements, this riser tube maintains contaminant removal efficiency exceeding 95 % at nominal flow rates. Its consistent internal diameter and low-friction surfaces support reliable monitoring of differential pressure, critical for scheduling filter service cycles. The 114477 design equally suits precision dispensing robots, plural-component proportioners, and continuous-feed coating lines that rely on accurate flow control and repeatable spray patterns under elevated temperatures and velocities. Optimized for high-pressure filtration arrangements, it delivers stable differential readings and minimizes maintenance downtime. Standardized port locations simplify control system integration.
Installation of the Graco 114477 SST riser tube demands strict adherence to torque specifications and alignment procedures. Apply anti-galling lubricant on threads to prevent seizing. Recommended assembly torque values for standard 7/16-20 UNF flare nuts are 25–30 ft-lb, applied with a calibrated torque wrench to ensure proper metal-to-metal sealing without overstressing the tube walls. Flare surfaces should be inspected for burrs or surface imperfections and cleaned with residue-free solvents prior to assembly. Routine maintenance schedules advise periodic disassembly to inspect for wear, corrosion, or micro-cracks using nondestructive methods such as dye penetrant or eddy current testing. During reassembly, use backup wrenches to prevent torsional loading, and always verify the absence of torque loss after initial pressurization cycles. Flush the line with compatible cleaning agents to displace trapped fluids and restore optimal flow characteristics before returning to service.
Overall, the Graco 114477 Tube Flare Riser Tube SST embodies precision engineering for demanding fluid-handling applications. Its low pressure-drop profile reduces energy consumption. Its robust stainless steel construction, stringent quality control, and compatibility with standard flare fittings make it a reliable component for industrial spraying systems, manifold assemblies, and specialized fluid delivery modules. By combining high tensile strength with polished internal passages and controlled surface finishes, the riser tube minimizes contamination risks and supports consistent coating thickness in multilayer applications. Integration with pump systems enhances operational uptime, while its mechanical resilience and corrosion resistance extend service life in harsh environments. Designers and maintenance engineers will appreciate the tube’s ability to withstand cyclic pressures, temperature extremes, and chemical exposure without compromising flow accuracy or system integrity, making it a cornerstone in advanced fluid management solutions.
