$32.97The Graco 113566 Packing O-Ring is a precision-engineered sealing component designed to maintain optimal performance in demanding fluid dynamics applications. Manufactured from high-grade elastomeric materials, this packing module delivers superior chemical resistance and thermal stability, ensuring consistent operation in modern airless sprayer and professional coatings systems. The O-ring’s streamlined cross-sectional geometry minimizes frictional losses while providing a robust barrier against fluid bypass. Throughout its operational lifecycle, the 113566 O-Ring Packing contributes to improved pump reliability by preventing cavitation and controlling leakage rates under extreme service conditions.
In fluid handling systems equipped with high-pressure filtration stages, the 113566 packing ensures uninterrupted flow rates by sustaining seal integrity even under differential pressures exceeding 5,000 psi. Its engineered lip profile effectively isolates the dynamic sealing surface from contamination, reducing wear during cyclic operation. The packing’s elastodynamic properties are optimized to resist compression set and extrusion, yielding stable sealing performance despite repeated shaft movements. Maintenance intervals can be extended by monitoring packing compression and verifying surface finish tolerances within the housing bore.
Performance assessments reveal a notable improvement in pump efficiency when retrofitting pumps with the 113566 O-Ring Packing. Controlled extrusion and controlled leak paths contribute to enhanced volumetric displacement and reduced internal recirculation losses. Empirical testing on spray systems indicates a 12 percent increase in fluid delivery consistency over 1,500 operational hours, while seal longevity exceeds 2,000 cycles under standard test protocols. When servicing legacy equipment such as piston-based applicators or diaphragm modules, compatibility with graco magnum x5 parts ensures a seamless integration without additional machining or housing modifications.
The core material used in the 113566 packing assembly is a specially compounded HNBR elastomer, selected for its exceptional tensile strength, low compression set, and resistance to hydrocarbon permeation. Secondary reinforcement elements include PTFE-coated fibers to reduce friction coefficients and promote smooth reciprocation. The packing’s outer sheath exhibits micro-textured ridges that enhance sealing contact and shed debris. Finite element analysis of the packing cross section has optimized stress distribution, minimizing peak strain concentrations that typically lead to premature failure.
Engineers deploying the 113566 Packing O-Ring in heavy-duty spray pumps will benefit from simplified assembly procedures. The packing slides effortlessly over the drive shaft, aligning within the gland cavity without requiring specialized tooling. Its standardized dimensions align with OEM tolerances, facilitating replacements in both new and legacy installations. Applications span high-viscosity coatings, solvent-based primers, and aqueous sealants used in industrial finishing, automotive refinish, and architectural coating lines. For complex fluid networks incorporating manifold blocks or multi-stage pump arrays, the packing maintains consistent sealing across variable pressure zones.
Regular maintenance protocols recommend a thorough inspection of the packing during service intervals. When replacing worn elements, reference the official Graco documentation and authorized repair data to ensure correct torque specifications and lubrication practices. Technicians can source compatible components through certified channels, including Graco Pumps Repair Kits, which provide matched seal sets and backup rings calibrated for the 113566 profile. Always verify gland surface finishes to be within 16 µin Ra to preserve optimal sealing contact.
Prior to installation, clean all mating surfaces and apply a thin film of lubricant compatible with the process fluid to the packing lips. Slide the O-ring into position, ensuring uniform seating around the shaft. Tighten the gland nut incrementally in a star pattern to distribute compression evenly and avoid eccentric loading. After initial run-up, re-torque to nominal values specified in the service manual to compensate for any material relaxation. End-users seeking detailed service guides or local technical support can locate their nearest distributor by searching graco store near me or consulting official service networks.
By integrating the Graco 113566 Packing O-Ring within high-pressure sealing assemblies, organizations achieve measurable gains in operational uptime and reduced downtime events. Consistent seal performance under harsh chemical exposure and thermal cycling assures process stability. For applications demanding top-tier fluid handling precision, this packing solution provides a robust foundation for advanced pump designs and next-generation finishing equipment.
