$22.74Graco 17E793 O-Ring Packing delivers robust sealing performance across a broad spectrum of fluid handling applications, from protective coatings to industrial adhesives. Crafted from high-performance elastomer blends, each ring undergoes rigorous dimensional verification to meet tight engineering tolerances. Chemical resistance spans solvents, waterborne formulations, and aggressive compounds, while temperature stability extends from sub-zero environments to elevated operational heat. Users benefit from reduced downtime thanks to consistent compression set resistance and minimal extrusion risk. Designed for both static and dynamic interfaces, this packing is a trusted choice when leak-free reliability and long service intervals are paramount in heavy-duty spray systems.
Development of this O-ring packing leverages proprietary elastomer formulations with an optimized durometer that balances hardness against flexibility. Molecular cross-link density is calibrated to resist swelling when exposed to aromatic solvents and alkaline cleaners. Precision-molded grooves and chamfered edges facilitate uniform compression distribution, reducing stress concentrations that can lead to premature fatigue. Integration with other graco sprayer accessories is achieved through consistent sizing standards, ensuring a watertight interface with pump housings and spray gun manifolds. In-house testing simulates millions of pressure cycles, verifying that elasticity and rebound characteristics remain within specification thresholds long after initial installation. Surface finish quality control minimizes frictional hotspots during dynamic movement, extending the lifecycle of both packing and mating metal components.
When mounted in diaphragm, piston, or roller pumps, this O-ring packing maintains seal integrity even under pulsating flows and abrupt pressure spikes. Void-free contact against polished rods prevents bypass leakage, ensuring volumetric efficiency remains above 98 percent in high-frequency operations. Genuine graco pump parts validation confirms alloy and coating interactions won’t degrade seal compounds, preserving consistent friction coefficients over extended service intervals. Advanced computational fluid dynamics (CFD) analyses demonstrate stable flow patterns around the seal lip, reducing cyclical loading and wear. Conformance with industry standards—such as ANSI B16.5 for flanged connections and ISO 9001 manufacturing protocols—adds an extra layer of confidence for engineers specifying this packing in mission-critical systems.
Preparation starts with a meticulous inspection of the seal bore and mating surfaces, ensuring they’re free from nicks or embedded particles. A thin film of silicone-based grease promotes initial ring seating without compromising compound integrity. During assembly, uniform radial compression is achieved by following torque sequences specified in technical bulletins. Scheduled maintenance should include visual checks every 250 operating hours in abrasive environments and bench testing of compression set at 500-hour intervals. Disassembly requires soft-edged extraction tools to prevent groove damage, followed by solvent wiping and inspection under magnification. Maintenance crews can leverage a dedicated graco gun repair kit to access calibrated wrenches, replacement fasteners, and alignment fixtures, resulting in faster turnaround and reduced risk of misapplication.
Performance audits under actual field conditions confirm that Graco 17E793 O-Ring Packing upholds sealing excellence without significant degradation, even in continuous-duty and high-cycle regimes. Its ability to resist compression set, ozone cracking, and thermal hardening makes it ideal for demanding industrial spray systems. Expert application support and comprehensive documentation facilitate correct selection, installation, and service planning. For organizations seeking to safeguard critical fluid delivery infrastructure, coupling this packing with a global technical support network and an industry-leading warranty program ensures uninterrupted productivity and full compliance with regulatory requirements.
