The Graco 17L555 gasket is engineered to deliver a tight seal for your pressure pot applications, ensuring smooth operation with a variety of professional coatings and primers. Designed to integrate seamlessly with your airless sprayer, this Viton gasket offers exceptional chemical resistance and reduces downtime by preventing leaks and material waste. Its robust construction stands up to continuous use, making it a top choice for contractors seeking reliability and performance. Its innovative design ensures consistent pump pressure and easy routine maintenance. Ideal for high-volume projects, it streamlines workflow and enhances coating uniformity.
Made from premium fluorocarbon elastomer, this gasket maintains integrity under extreme temperatures and harsh solvents, supporting precise delivery and high-pressure filtration. Perfectly suited for industrial and commercial use, it withstands aggressive solvents and abrasive coatings. Easy to install and clean, it safeguards your equipment investment and contributes to professional results across diverse painting and coating projects.
Engineered to endure high operational pressures and exposure to aggressive coatings, this gasket delivers unmatched sealing performance in professional-grade spray systems. Graco 17L555 Viton gasket ensures fluid containment within pressure pots, preventing leaks that can compromise finish quality. Precision molding techniques yield consistent cross-sectional dimensions, eliminating the need for iterative adjustments during installation. Whether handling solvent-based enamels or waterborne lacquers, this gasket upholds integrity across temperature extremes and chemical environments.
Utilizing a fluorocarbon backbone, Viton exhibits exceptional resistance to swelling, hardening, and compression set when in contact with solvents, acids, and oils. Its molecular structure provides high tensile strength and elongation properties, preserving seal geometry after thousands of pressure cycles. Operational temperatures ranging from –20°C to 200°C are well within its performance envelope, while peroxide curing enhances tear resistance and reduces surface cracking. This combination of attributes ensures consistent compression characteristics, even under cyclic stresses found in industrial spraying environments.
For optimal system longevity, pairing Graco 17L555 with high-efficiency graco paint sprayer filters is recommended. Filter assemblies rated between 20 to 60 microns efficiently capture debris originating from material lines or previous system wear. By intercepting particulates before they reach the pressure pot, these filters mitigate abrasive damage at the seal face and extend maintenance intervals. Equally important is selecting filter housings compatible with your coating viscosity; a cohesive filtration routine directly correlates to extended gasket service life and uniform atomization.
Optimized seating geometry ensures no compromise when attached to standard graco paint sprayer hoses, preserving flow rates and preventing unplanned downtime. Hose assemblies reinforced with wire braids or textile fibers rely on gasket conformity to prevent pressure-driven displacement. Torque recommendations suggest clamp loading between 15 to 20 ft-lbs, evenly applied in a star-pattern to maintain flange parallelism. This approach eliminates stress concentrations that could otherwise lead to micro-leaks or rapid gasket fatigue under fluctuating pressures.
Correct functioning of pressure pot systems depends on a leak-free supply at the spray gun. By inspecting surrounding graco paint sprayer gun parts—including fluid needles, seats, and swivel fittings—operators can identify weak links before gasket replacement. A tight seal at the pot minimizes air ingress, stabilizing spray patterns and reducing pulsation. Consistent fluid pressure translates to precise atomization, sharper definition on corners, and reduced overspray, supporting high-quality finishes and fewer touch-ups.
Before fitting a fresh gasket, purge the pot and flush residue with an approved solvent. Carefully remove the clamp band and pot lid, taking care to note alignment keys. Inspect mating surfaces for nicks or corrosion using a magnifier and smooth any imperfections with a fine Scotch-Brite pad. Apply a thin layer of non-reactive lubrication such as silicone grease to facilitate initial seating. Sequenced hand torque of the lid clamp in opposing quadrants ensures uniform compression. After assembly, perform a low-pressure air test, gradually ramping to full operating pressure while checking for any evidence of seepage. Detailed cleaning protocols recommend using non-chlorinated solvents and lint-free wipes to avoid fiber contamination. A calibrated torque wrench can verify clamp forces precisely, preventing ozone degradation from over-compression. Periodic humidity-controlled storage further preserves elastomer properties before use, ensuring gasket readiness even after extended downtime.
Cumulative operational cycles and chemical exposure can subtly alter gasket properties over time. Monitoring seal compression and scheduling replacements based on cycle counts, rather than visual deterioration alone, prevents unexpected downtime. Storing Viton gaskets in a cool, dark environment away from ozone sources further prolongs shelf life. Keeping critical spares on-hand is recommended for production facilities, allowing swift swap-outs during routine maintenance windows. Consistent performance hinges on proactive upkeep and adherence to manufacturer guidelines.
Suited for automotive refinishing, wood coatings, or heavy-duty industrial applications, Graco 17L555 demonstrates unwavering seal integrity across multiple sectors. Field trials in marine environments exposed to salt spray revealed minimal flange corrosion and sustained leak-free operation over extended intervals. In high-volume production lines using low-VOC polyurethane primers and topcoats, its low gas permeability limits solvent bleed-through and supports environmental regulations. Rapid material changeovers—such as switching from epoxy-based primers to acrylic topcoats—require only a thorough pot flush rather than gasket removal, boosting downtime efficiency. Compatibility with anti-static agents further ensures safety in explosive atmospheres, making this gasket ideal for spray booths and mixing stations handling flammable coatings.
