$7.94The Graco 108822 Packing O-Ring is a precision-engineered sealing element tailored for advanced fluid delivery modules in industrial painting and lubrication systems. Designed to interface directly with the fluid section of high-pressure pump assemblies, this component excels in maintaining zero-leakage dynamic seals even under extreme pressure cycling. Within a typical airless sprayer module employing a graco airless paint sprayer, the Packing O-Ring is subjected to pressures exceeding 3000 psi and temperatures spanning –20 °C to 70 °C, ensuring reliable performance for demanding applications ranging from automotive clearcoats to architectural professional coatings lines. Its compatibility with high-pressure filtration arrays further enhances contamination control and system integrity.
Optimizing seal chamber performance in cylinder packs and reciprocating pump rod boots, the Graco 108822 Packing O-Ring contributes directly to overall pump efficiency by minimizing volumetric slip and reducing cycle-to-cycle pressure losses. When integrated into a sprayer machine paint assembly, this packing set reduces mechanical friction wear rates and extends maintenance intervals without compromising flow rates. Designed for compatibility with a wide range of substrate viscosities and additive packages, the element sustains seal longevity through thousands of dynamic cycles. Key performance metrics include static leak ratings below 10⁻⁶ cc/min, dynamic leakage under 15 drops/min, and friction coefficients less than 0.15.
Under rigorous tolerance analysis, the Graco 108822 Packing O-Ring features a precisely controlled cross-sectional profile that ensures uniform gland loading and radial compression around piston rods and packer boats. The packing ID and OD dimensions are maintained within ±0.02 mm to guarantee concentricity and prevent pressure imbalances. Its multi-lip architecture incorporates a primary sealing lip, a secondary backup lip, and an integrated wear ring to stabilize axial movement. This design minimizes extrusion risk in extreme pressure scenarios and provides consistent sealing performance in both static and reciprocating applications. The geometric profile supports seamless integration with standard Graco pump manifolds and cylinder housings.
Material selection for the 108822 packing balances elasticity, chemical stability, and wear resistance by utilizing an advanced composite of nitrile rubber with PTFE fiber reinforcement. The dynamic sealing lip comprises a 70 durometer nitrile blend that provides low friction and high abrasion resilience, while the PTFE reinforced backup section offers chemical inertness against solvents, coatings resins, and waterborne additives. This hybrid formulation ensures compliance with industry safety standards for volatile organic compounds and maintains dimensional stability up to 70 °C. The seal’s chemical resistance enables use with alkyds, epoxies, and solventborne or waterborne professional coatings systems, supporting high-pressure filtration regimes without degradation.
Proper installation of the 108822 O-Ring Packing begins with meticulous gland surface preparation and inspection for scratches or score marks. Lubricating the seal with compatible low-viscosity grease minimizes initial dynamic friction and prevents lip roll. Using calibrated torque wrenches, assembly bolts are retightened to specified preload settings, distributing radial compression uniformly across the seal. Routine maintenance schedules should include periodic inspection of pump rod runout and replacement of worn or extruded elements to preserve pump efficiency. When replacing the packing, adherence to manufacturer torque sequences and verification of alignment ensure consistent seal longevity under continuous duty cycles.
In field deployments, the Graco 108822 O-Ring Packing is employed across a spectrum of high-volume coating operations, including automotive primer lines, marine hull treatments, and architectural facade finishes. Integrated into spray circuits, the seal supports consistent fluid delivery for demanding tasks such as high-build acrylic layering, epoxy floor coatings, and corrosion-resistant metal primers. Its robust design resists washout in waterborne processes and withstands abrasive pigment slurries. Compatible with Graco Ultra pump modules and modular packer boats, the packing optimizes airless pressure control, allowing technicians to achieve uniform film thickness and edge definition in professional settings.
Selecting the Graco 108822 Packing O-Ring ensures superior seal life and reduces downtime in heavy-duty spray systems. The combination of precision tolerances, multi-material chemical resistance, and engineered lip profiles drastically extends service intervals and improves economic return on investment for coating contractors. Integration with pump sets such as the graco ultra 395 series and custom manifold blocks maximizes compatibility across fluid delivery systems while preserving key metrics like bleed rates, pump efficiency, and seal longevity. For system engineers focused on high-performance airless sprayer designs, this O-Ring Packing stands as a critical component in achieving leak-free, high-output coating processes.
