The Graco 18A558 Hose, Coupled, 100' x 3/4" delivers durability and performance for demanding applications. Engineered for Graco 18A558 systems, this hose ensures consistent flow and precise spray patterns. Its robust construction handles high-pressure filtration requirements while minimizing downtime. Ideal for use with any airless sprayer, it maintains stability under heavy loads and offers superior resistance to kinks and abrasion within professional coatings environments. Compatible with oil-based and latex coatings, it supports seamless transitions and reduces overspray, boosting jobsite productivity.
Featuring 100 feet of seamless construction and a 3/4-inch diameter, this hose, coupled design optimizes transfer rates and reduces operator fatigue. A built-in stainless-steel braid enhances strength and extends service life for operations in large-scale coating applications. Its integrated coupling delivers leak-free connections for professional coatings projects, while the abrasion-resistant cover withstands harsh jobsite conditions. Backed by Graco’s reputation for innovation, it’s the go-to accessory for contractors seeking reliable performance in tough industrial environments.
Designed for demanding industrial and commercial painting tasks, Graco 18A558 Hose, Coupled, 100' x 3/4" offers a blend of flexibility and strength that professionals trust on job sites ranging from automotive refinish to large-scale architectural coatings. Every element—from the heavy-duty braid reinforcement to the corrosion-resistant couplings—has been engineered for repeatable performance, ensuring minimal downtime and consistent spray quality in high-pressure applications.
Robust coupling assemblies play a crucial role in maintaining system integrity. Standardized thread profiles and O-ring seals guarantee a secure interface between hose and pump, preventing fluid blowback and operator hazards. Field technicians appreciate that couplings meet industry torque specifications, which eliminates guesswork during installation and service intervals.
Performance at extreme conditions sets this hose apart. Rated for continuous operation at 4000 psi (275 bar) and capable of handling up to 10,000 psi (690 bar) burst tests, it excels in environments where pressure spikes are common. Temperature tolerances range from -40°F to 200°F (-40°C to 93°C), enabling use with solvent-based coatings, waterborne materials, and specialized industrial fluids without compromising tube integrity.
Situations requiring particulate control benefit when it’s paired with graco paint sprayer filters. Inline cartridge filters trap contaminants before they enter the hose lining, reducing abrasion-induced failure and preserving finish uniformity. Filter maintenance schedules can be aligned with hose inspections to simplify preventive maintenance.
Material engineering underpins the hose’s durability. Inner tubes are crafted from oil-resistant synthetic rubber that resists swelling and chemical attack, while the outer cover features a tough nitrile compound that stands up to scuffing, weather, and accidental impact. A balanced steel-wire braid sits between these layers, providing hoop strength to withstand internal pressure and external abuse.
Customization options include on-site length adjustments and specialized coupling upgrades. Field service teams can re-terminate ends with quick-disconnect fittings, camlock adaptors, or stainless steel swivel couplings to match unique equipment layouts. Such flexibility streamlines integration into existing sprayer networks without necessitating full system overhauls.
Contractors often specify assemblies alongside graco paint sprayer hoses and other OEM components to ensure system compatibility. Matching hose families eliminates concerns about mismatched pressure ratings or material incompatibilities, resulting in a cohesive fluid delivery system with predictable performance characteristics.
Third-party laboratories and in-house testing protocols verify compliance with environmental health and safety regulations. Hydrostatic testing procedures simulate worst-case scenarios, confirming that each hose can endure repeated load cycles. Dimensional checks ensure consistent inner diameters, which directly impact fluid velocity and atomization quality.
Fluid transfer continuity is critical when paired with spray guns. Precision engineering in conjunction with graco paint sprayer gun parts reduces dead zones where sediment might accumulate, facilitating quick color changes and reducing cleanup times. Combination trials confirm that this hose supports high-volume output without inducing pulsation or cavitation.
Storage and handling considerations include proper coiling techniques to prevent permanent memory set. Recommended support racks and mild bends help maintain hose roundness and guard against kinking, which can restrict flow and create stress points. Seasonal environmental factors such as temperature swings should be accounted for to maintain flexibility over prolonged storage.
Routine servicing involves visual inspections for cover wear, coupling integrity checks for secure threading, and pressure tests to reveal hidden flaws. Cleaning guidelines advise flushing with compatible solvents immediately after use to eliminate chemical residues that could degrade internal material over time.
Extended warranty options and preventive maintenance contracts are available to maximize uptime. Certified service engineers provide on-site replacement, end-of-season winterization services, and calibration of torque settings on couplings. Regularly scheduled visits mitigate unexpected failures and uphold project timelines.
For contractors and rental operations alike, specifying Graco 18A558 Hose, Coupled, 100' x 3/4" ensures access to reliable parts and expert support. Trust in professional service agreements for hose replacement, preventive inspections, and system audits to extend service intervals and maintain peak performance.
