The Graco 17L393 accessory is a precision-engineered tubing solution designed to optimize fluid transfer and prevent clogging in your spraying system. With seamless compatibility for airless sprayer operations, it incorporates advanced high-pressure filtration to ensure consistent flow control and extends the service life of pumps and hoses. Contractors and Tube, Drain maintenance crews focused on professional coatings projects will value its durable construction and corrosion-resistant finish, which withstand demanding jobsite conditions while reducing downtime during cleanout. Its compact profile allows quick installation and seamless integration into existing setups, delivering reliable performance on every project while keeping operations running smoothly. Its precise dimensions—measuring just 13.95 inches in length and less than half an inch in height—fit neatly into tight spaces, minimizing bulk. Engineered to meet rigorous OEM standards, this component ensures smooth draining and prevents fluid backflow during equipment shutdowns. Whether retrofitting existing systems or upgrading new setups, it delivers consistent, heavy-duty performance.
Graco 17L393 tube is an essential component engineered for efficient fluid evacuation in high-performance spraying systems. Precision-machined couplings and corrosion-resistant tubing reduce downtime and ensure consistent material flow during routine maintenance or equipment changeover. Offering a balance of robustness and flexibility, this drain line integrates seamlessly into demanding production environments where reliability and rapid cycle times are non-negotiable.
Constructed from electropolished stainless steel, Graco 17L393 resists chemical attack while maintaining structural integrity under high-pressure backflows. Electropolishing enhances surface smoothness, preventing residue buildup that can compromise seal integrity over long service intervals. Material selection reflects decades of fluid-handling expertise and addresses the need for parts that endure harsh solvent-based coatings without degradation.
Flexible design allows integration with a wide variety of pump configurations, including high-output piston pumps and centrifugal systems. Compatibility extends to proprietary sprayers, with direct interface capabilities for the graco x7 airless paint sprayer. Installation kits for older model sprayers are available for seamless fluid return when used with graco 395 paint sprayer lines. System layout optimization benefits from this tube’s consistent internal diameter and defined wall thickness, maintaining laminar flow characteristics essential for precise coating applications.
Pre-installation inspection should verify that O-rings and compression fittings remain free of debris. A clean connection surface ensures sealing integrity, minimizing the risk of bypass leaks under pressurized operations. Torque specifications published in the equipment manual must be followed carefully. Using calibrated tools will prevent over-tightening that can stress threads or deform soft-metal fittings.
Service intervals for Graco 17L393 vary depending on fluid type and operating temperature. Visual checks for early signs of stress cracking or weld fatigue can extend service life by identifying wear points before catastrophic failure. Lubrication with manufacturer-approved release agents simplifies disassembly. For advanced diagnostics, refer to the graco 395 parts diagram to confirm correct alignment during system rebuilds and to ensure that gaskets and back-up rings seat properly.
Real-world testing under cyclic load profiles demonstrates exceptional resistance to flow pulsation, even after hundreds of thousands of cycles. Users report improved throughput consistency and zero recorded leakage in continuous operation over extended periods. This tube’s reliability translates into lower maintenance budgets and reduced downtime, especially in high-volume production environments where fluid changeovers occur daily.
Configurable lengths and flange styles allow seamless integration into bespoke fluid management setups. Quick-disconnect options, swivel fittings, and extended reach variants can be ordered to match precise layout constraints. Graco offers engineering support to tailor tube assemblies with specific hardness grades, flare angles, or material alloys upon request, ensuring that specialized coatings or adhesives flow without obstruction.
Manufacturing processes comply with ISO 9001 and adhere to NACE MR0175 requirements for sour service compatibility. Batch traceability is maintained through QR-coded tags on each assembly. Material test reports (MTRs) accompany every shipment, providing documentation for mechanical properties and chemical composition. Such rigorous oversight ensures that tube integrity aligns with global safety and performance standards.
Graco’s commitment to durability extends beyond production lines, featuring a global network of certified technicians ready to assist with preventive maintenance plans and emergency repairs. Authorized channels supply genuine replacement kits and offer on-site inspection to validate system integrity. Users can subscribe to performance audits that include pressure profiling and component life-cycle analysis, ensuring long-term reliability for critical applications.
