The precision-engineered Graco 17L386 fitting is a robust PTC push-to-connect component designed to seamlessly integrate with airless sprayer systems. Featuring top-quality brass construction and a tight seal, this 3/8” tube x 1/8” barb adapter ensures consistent fluid flow under demanding conditions. Ideal for high-pressure filtration setups, it delivers exceptional performance in challenging environments, resists wear and corrosion, and promotes streamlined installation with minimal downtime. Its compact footprint makes retrofitting into existing lines effortless.
Engineered for durability and precision, the Graco 17L386 fits into a range of airless and conventional spray systems, maintaining optimal seal integrity even under surge pressures. Its push-in mechanism allows quick tool-free connections, improving workflow efficiency for professionals applying professional coatings. Whether in automotive, industrial, or architectural projects, this fitting delivers unmatched reliability and consistent results.
Graco 17L386 Fitting, Ptc, 3/8 Tube X 1/8 Barb stands out as a compact yet powerful connector engineered for demanding fluid systems in coatings, adhesives, and lubrication circuits. Designed to meet rigorous industrial standards, this precise coupling offers leak-free performance while minimizing installation complexity. Integration into confined spaces is facilitated by its low-profile body, and the barb-to-tube interface ensures a secure seal under variable pressure cycles. Maintenance routines become simpler thanks to corrosion-resistant surfaces and consistent torque specifications that prevent overtightening. Professionals seeking to optimize fluid delivery across diverse applications will find this component indispensable.
Graco engineers have crafted the 17L386 module using premium-grade zinc-plated carbon steel that withstands corrosive agents and mechanical wear. Precision machining tolerances on the 3/8-inch tube end ensure consistent concentricity, preventing fluid channel misalignment and pressure loss. Barb geometry features multiple ridges that grip tubing with optimal force distribution, creating a tight interference fit. Surface treatment employs an advanced electroless nickel coating for enhanced oxidation resistance and long-term performance under high-cycle conditions. Threads are cut to exact ASME standards, guaranteeing compatibility with existing PTC manifolds and quick-connect assemblies. Compact geometry combined with a minimal footprint allows integration into complex manifolds or valve banks without crowding adjacent fittings.
High-cycle sealing integrity of this Ptc coupling relies on a combination of optimized barb contour and controlled deformation of the tubing wall, resulting in reliable leak prevention across varying temperatures. Rated for continuous operation at pressures up to 235 psi and intermittent spikes approaching 500 psi, this fitting excels in demanding fluid circuits such as high-viscosity coatings and solvent-based adhesives. Corrosion resistance is bolstered by zinc-phosphate pretreatment followed by clear-passivation finish, delivering extended service life in harsh environments. Engineers will appreciate the consistent torque-to-yield performance, which eliminates the risk of overtightening or thread galling during repetitive maintenance intervals.
Quick assembly procedures reduce downtime by permitting hand-start threading before final torque application with a calibrated wrench. Recommended tightening torque of 10–12 ft-lbs achieves optimal seal compression while preserving thread integrity; maintenance teams should verify torque periodically to avoid seal fatigue. Removal is equally straightforward, allowing disassembly without damaging adjacent components. Routine inspections of tube engagement depth and barb deformation are encouraged, ensuring that any material wear or tubing recrimping is detected early. Compatibility with common assembly tools and simple service checks make this fitting a reliable choice for technicians in busy production settings.
Integration into larger spray systems often demands adapters that match various equipment brands. Compatibility tests show that it pairs seamlessly with the x7 paint sprayer, providing a leak-free hydraulic path even under rapid flow changes and high-pressure rebound cycles. System performance improves thanks to reduced pressure drop at coupling interfaces, while operators benefit from straightforward assembly and maintenance protocols.
Systems based on established fluid-handling platforms have demonstrated excellent performance when fitted with our connector. Field evaluations confirm reliable operation alongside the graco 395 sprayer, where consistent torque settings and precise barb design minimize downtime and fluid wastage during color changes or line flush procedures. Maintenance crews report faster turnaround and fewer seal-related incidents compared to generic alternatives.
Contractors who rely on portable finishing units find value in components that integrate effortlessly. Our fitting has been successfully tested with the magnum x5 paint sprayer, delivering stable pressure control and consistent surface coverage. Attention to barb-seat engagement and recommended tubing specifications ensures spray patterns remain uniform, resulting in superior finish quality and reduced material overspray.
Precision fluid connectors like the 17L386 fitting exemplify how small components can have a significant impact on overall system reliability. Proper selection of fitting material, accurate torque application, and thorough inspection protocols form the backbone of any high-performance fluid network. It is advisable to adhere to documented service intervals that include tube replacement, torque retesting, and surface condition checks. Using purpose-designed tools for assembly and disassembly prevents accidental damage to sealing surfaces. Should any coupling require professional attention, our comprehensive installation service and preventative maintenance packages ensure minimal downtime and optimal performance.
