In advanced coating pumps, the internal union profile of the Graco 114446 reduces turbulence and pressure drop across each coupling interface. The machined bore diameter of 3/8 inch provides optimal volumetric throughput, while the forged fitting body resists deformation under cyclical loading. Incorporating high-tolerance O-ring grooves and an integrated backup ring, this union fitting enhances seal longevity without compromising flow rates. The 90° elbow configuration addresses spatial constraints in complex piping layouts, simplifying manifold integration within modular sprayer units. Field tests demonstrate that the component maintains stable performance under temperatures ranging from –20 °C to 100 °C, with corrosion resistance maintained via electropolished passivation. Operators note measurable improvements in pump efficiency and smoother pump stroke transitions attributed to the refined fluid pathway geometry. This level of flow optimization supports extended service intervals in demanding industrial finishing environments.
Operators tasked with maintaining high-volume airless sprayer rigs benefit from the directional control afforded by the 90° union design. In assembly sequences, the fitting’s smooth torque-to-yield ratio ensures repeatable clamp force without overloading internal threads. Combined with high-pressure filtration modules, the fitting interfaces seamlessly with inline filter housings, preventing particulate ingress downstream. Recommended torque values between 25 and 30 Nm preserve O-ring compression within specified thresholds, optimizing sealing life. Periodic inspection of the electropolished surface for abrasion marks and thorough cleaning with compatible solvents extends operational continuity. The modular nature of the union allows swift replacement during preventive maintenance, reducing overall system downtime. Detailed torque and assembly protocols are documented in Graco’s service manuals for reference during field repairs.
Crafted from 316L stainless steel, the Graco 114446 withstands aggressive solvents and abrasive media common in professional coatings operations. The acid-resistant alloy composition provides exceptional corrosion resistance, while the electropolished inner bore minimizes surface roughness that can trap particulates. Thermal cycling between –20 °C and 100 °C tests have verified uniform expansion properties, which reduce stress on O-ring seals and ensure consistent thermal stability. The precision-machined flange faces maintain flatness within 0.02 mm, sustaining uniform contact pressures essential for leak-free performance. Integration of Viton® or PTFE sealing elements further enhances chemical compatibility, extending service intervals in corrosive environments. Engineers report that components sustain over one million cycle operations without measurable performance degradation, underlining the part’s durability in high-demand industrial settings.
In complex fluid delivery networks, the Graco 114446 Union Fitting, Union 90°, excels at integrating pump sections, valve clusters, and manifold blocks with minimal reconfiguration.
