$22.35The Graco 15X870 Tube Air 3/8" is a precision-engineered conduit designed to deliver consistent fluid flow under demanding industrial conditions. Manufactured with robust elastomeric polymers and reinforced with stainless steel wire braid, it ensures uniform wall thickness and high tensile strength. Ideal for airless sprayer platforms, it excels in transferring professional coatings, solvents, and adhesives while maintaining system integrity across a wide temperature range. At approximately one pound per foot, its nominal outer diameter of 0.56" and 0.38" inner bore ensure compact routing in confined spaces without sacrificing volumetric flow.
The sectioned braid construction enhances kink resistance and minimizes pressure drop across long runs, contributing to overall pump efficiency. Its low-swell fluoropolymer lining resists degradation from abrasive compounds, ensuring extended service intervals. Precision crimped fittings maintain leak-free joints, reducing downtime. The 0.025" PTFE liner thickness provides a smooth bore for reduced drag, while an outer cover hardness of Shore A 85 resists gouging. This configuration supports consistent volumetric output within ±2% tolerance, critical for automated mixing systems and real-time process control.
In automotive paint booths, the 15X870 tube ensures uniform deposition of basecoat and clearcoat layers, facilitating rapid cure cycles with droplet sizes under 20 microns. In aerospace assembly lines, it transports sealants and adhesives at precise flow rates, while in heavy machinery production, it delivers polymers for vibration damping. Its adaptability to CNC-controlled dispensing heads makes it ideal for integration with robotic applicators and multi-component proportioning systems.
Extensive bench testing confirms a maximum burst pressure of 4,500 psi at ambient temperature and fatigue life exceeding 1 million flex cycles. Flow coefficients (Cv) are maintained above 0.65, and pressure retention remains stable over 500 hours of continuous operation. High-pressure filtration compatibility ensures particulate removal down to 5 microns, preserving downstream component integrity. Accelerated hydrostatic cycle tests follow ISO 6803, enabling predictive maintenance scheduling based on high-fidelity performance data.
Graco’s specialized inner bore design balances laminar flow with efficient heat dissipation, minimizing temperature-induced viscosity shifts during continuous operation. The tube maintains dimensional stability up to 200°F, preventing softening or collapse under cyclic pressure. Analytical modeling shows less than 0.5% volumetric change per 10°F variation. Its thermal conductivity facilitates rapid cooldown in intermittent spray cycles, supporting precise color matching and consistent atomization when switching between high-temperature and ambient media.
The core lining utilizes PTFE for chemical inertness, while an extruded nylon cover layer adds abrasion resistance. A multi-angle stainless steel braid resists radial expansion, and the outer polyurethane sheath shields against environmental contaminants. All components meet ISO 8031 standards, and the assembly process includes computerized extrusion control to maintain dimensional tolerances within ±0.01". Traceability coding on each section supports full material certification for critical industrial processes.
Cylindrical crimp connections employ interchangeable collars to accommodate NPT, BSP, or metric thread standards. FKM O-rings and Viton seals preserve joint integrity at thermal extremes, facilitating seal longevity beyond 2,000 thermal cycles. Rapid-connect couplings enable tool-free assembly for quick maintenance shutdowns and modular reconfiguration. Electroless nickel plating options are available for specialized environments, including food-grade and pharmaceutical manufacturing compliant with FDA 21 CFR part 177.2600.
Periodic inspection focuses on identifying abrasion spots, micro-cracks, or delamination along the tube length. Automated ultrasonic scanning can detect internal voids preemptively. System flushing protocols using compatible solvents remove particulates and biofilm, and torque checks on fittings prevent stress concentrations. Replacement intervals align with ISO 14743 recommendations and OSHA 1910.106 solvent vapor containment guidelines.
The 15X870 tube interfaces seamlessly with high-volume spray pumps and proportioning manifolds, supporting multi-component paint lines. Tubing run layouts optimize manifold spacing to minimize pressure drop, while quick-disconnect adapters enable rapid color changeovers. Its compatibility with HVLP and air-assisted airless modules extends its versatility across OEM and refinish operations. The tube’s low-permeation profile meets environmental regulations for volatile organic compound emissions.
The 15X870 tube is compatible with a range of proprietary fittings, including quick-spin couplings and rapid palette connectors. Custom cut-to-length services and color-coded outer sheaths aid in line identification for multi-channel systems. Modules can be pre-assembled with pressure transducers or thermocouples at defined intervals, enabling real-time monitoring without additional field instrumentation. This modular approach reduces installation time and supports scalable system expansions in phased deployment scenarios.
Engineered for durability and performance, the Graco 15X870 Tube Air 3/8" offers a reliable solution for precision fluid delivery in high-demand applications. Its balanced design prioritizes flow consistency, pressure containment, and chemical resistance. By integrating this tube within advanced process systems, engineers can optimize operational uptime, reduce maintenance costs, and achieve superior finish standards across industrial and commercial spraying tasks. Graco’s global support network provides detailed application guides and calibration services to maximize lifecycle performance without compromising safety.
