$257.19The Graco 162617 retainer packing is a critical component in advanced pump assemblies, engineered for demanding industrial environments. Manufactured by Graco to OEM specifications, this retainer packing secures gland seals under fluctuating loads and high dynamic forces. Its compact profile integrates seamlessly into piston and diaphragm pumps, ensuring consistent preload on the packing set. Designed for robust performance, the retainer packing excels in heavy-duty cycles, extending operational uptime and reducing unscheduled service interventions.
Constructed from high-grade PTFE composites combined with dynamically stabilized elastomers, the retainer housing resists deformation and extrusion at elevated temperatures. Specialized nitrile seals adapt to volumetric changes while preserving sealing integrity. The assembly meets rigorous ISO 9001 traceability standards and is compatible with a wide range of process fluids. In fact, the retainer packing is optimized for airless sprayer pump modules where fine particulate or solvent-based coatings are common.
Performance testing demonstrates exceptional flow control across a thermal band of -40 °F to 300 °F, maintaining leak-free operation under cyclic loading. Computational fluid dynamics (CFD) analysis confirms that seal face deflection remains below critical thresholds, directly enhancing pump efficiency in high-speed applications. The design minimizes pressure bleed past the packing set, ensuring precise volumetric delivery even under rapid actuation.
Surface finish and geometric precision drive compatibility with modern filtration systems. Coating lines and metal finishing plants often incorporate the 162617 retainer packing for its unparalleled resilience against abrasive media and solvent chemistry. The part supports both conventional coatings and advanced professional coatings chemistries, seamlessly integrating into closed-loop circuits for continuous recirculation. Additionally, its architecture withstands repeated engagement with high-pressure filtration cartridges without performance degradation.
Within heavy manufacturing, the retainer packing secures critical seals in pumpheads for concrete placement, automotive paint robots, and food-grade pumping stations. Its retention ring design ensures uniform load distribution across multi-lip seals, crucial for high-volume fluid transfer. Aerospace component suppliers rely on 162617-based systems to maintain clean-room standards, leveraging the retainer’s metal-to-metal fit to eliminate particulate traps and ensure compliance with stringent quality audits.
Routine inspection involves measuring seal protrusion and wear-ring clearance to preemptively address performance drift. Installation requires a calibrated torque wrench; recommended values range from 25 to 30 ft·lb to achieve optimal gland compression. Use of PTFE-compatible greases during reassembly reduces initial run-in friction. These best practices contribute directly to extended seal longevity, cutting downtime and service costs over the operational lifecycle.
Compatibility extends to Graco’s quick-change replacement system: technicians can swap out a worn retainer packing in under 10 minutes, thanks to indexed alignment features and color-coded retention springs. The part number 162617 corresponds with multiple series of diaphragm and piston pumps, reducing inventory complexity and avoiding cross-reference errors.
Rigorous quality control includes dye-penetrant inspection of each retainer body, pressure-cycle validation at 150% of rated operating pressure, and hardness verification of all critical surfaces. Statistical process control (SPC) charts monitor dimensional consistency, ensuring each batch meets exacting engineering standards. Life-cycle testing confirms over 500,000 cycles before threshold wear limits are reached, providing confidence in high-duty applications.
In summary, the Graco 162617 retainer packing combines superior materials, pinpoint machining, and rigorous testing to deliver reliable performance in the most challenging fluid handling environments. Its integration into industrial and commercial pump systems elevates reliability, reduces maintenance frequency, and ensures smooth operation in high-pressure assemblies—from paint sprayers to chemical metering stations.
