$25.66The Graco 100505 Bushing Pipe is a precision-engineered steel component designed to secure pipe segments within fluid delivery assemblies. Featuring a 3/4M x 3/8F thread interface, this OEM bushing weighs 0.2 lbs and measures 1.25 x 1.2 x 1.25 inches, optimizing flow path and structural rigidity within high-pressure fluid conveyance modules. In professional airless sprayer installations, the part supports consistent internal alignment and pressure containment at extrusion points, protecting seal surfaces against mechanical fatigue and chemical assault. Detailed machining tolerances and material selection ensure compatibility with progressive cavity housings and piston pump heads.
Crafted from high-strength alloy steel subjected to controlled heat treatment, the Graco 100505 bushing exhibits exceptional hardness and wear resistance. Machining tolerances of ±0.005 inches preserve concentricity across the 3/4M x 3/8F coupling interface, minimizing vibration and enabling smooth fluid transition. Surface treatments including black oxide passivation or optional chrome plating inhibit corrosion from solvent- or water-based coatings. Engineers benefit from precise geometric profiles that maintain alignment within piston pump manifolds and swivel fittings under cyclic pressure loads.
In endurance testing at 3,000 psi continuous pressure, the bushing demonstrates negligible dimensional drift over 100,000 cycle iterations, supporting consistent volumetric throughput with minimal leakage. Its optimized bore geometry promotes uniform flow velocity, enhancing pump efficiency by reducing internal turbulence and pressure drop. Furthermore, controlled surface roughness below 16 μin RMS reduces seal wear, extending component life. Laboratory evaluation confirms seal longevity exceeding 1,000 hours under dynamic reciprocating conditions, validating the part’s suitability for prolonged field operation.
The 100505 interface seamlessly integrates with multiple Graco pump families and manifold blocks via standard thread specifications. Installation into hydraulic sections, fluid sections, and swivel couplings is straightforward, engaging ISO 7/1 threaded passages with robust torque retention. This bushing also accommodates higher flow rates in low-pressure, low-volume spray applications. When paired with hplv paint guns, it stabilizes inlet connections and prevents pressure spikes, ensuring uniform atomization. Field technicians can interchange bushings without modifying existing piping layouts, maintaining optimal spray profiles.
Proper installation relies on calibrated torque application—typically 20–25 ft-lbs—to achieve a leak-tight seal while avoiding material deformation. Thread sealing compounds or PTFE tape may be applied sparingly to peripheral threads to reduce potential galling. Scheduled maintenance intervals of 3–6 months, depending on fluid viscosity and abrasive particle content, help technicians detect thread wear early. Compatible with standard Graco tools and system diagnostics, the bushing simplifies breakdown procedures. Integration within graco spray rigs benefits from modular assembly lines that expedite part replacement in high-throughput environments.
Engineers rely on the 100505 bushing when formulating solutions for protective epoxies, polyurea membranes, and solvent-based urethanes. Its precision alignment capabilities are critical for ultra-thin film applications that demand screw-on fluid tips, maintaining constant pressure for accurate layering. In automotive and industrial painting, the component underpins spray pack stability, contributing to consistent droplet sizes and reduced overspray. When deployed with high-performance pumps, it supports demanding cycles in commercial painting booths, reinforcing standards for professional coatings and surface finish uniformity across complex geometries.
Routine inspection of the 100505 bushing under high-pressure filtration systems helps identify contamination or metal particulate buildup. By integrating inline filters rated to 50 microns or finer, operators significantly reduce abrasive wear. Periodic replacement of the bushing, coupled with lubrication of mating threads, can extend service life by up to 25%. The robust material profile resists pressure spikes and thermal cycling, further preserving component geometry. These best practices ensure extended seal longevity and support continuous duty cycles in demanding industrial spray operations.
Across construction, marine, and heavy equipment sectors, the Graco 100505 bushing is a critical component in turnkey airless systems. It maintains conduit alignment for both rigid and flexible hoses, ensuring stable feed into hydraulic piston pumps. Technicians can retrofit existing manifolds without machining custom adaptors, leveraging consistent thread pitches. When integrated into an airless graco spray gun, the bushing delivers smooth pressure transitions at gun inlets, reducing cycle downtime. This reliability is essential for large-scale coating projects where uninterrupted material delivery is paramount.
Upgrading to the Graco 100505 bushing supports future-proofing of fluid delivery modules, enabling easy adaptation to next-gen pumps and proprietary fittings. Its standardized thread interface may accommodate optional sensor ports, facilitating pressure and temperature monitoring for predictive maintenance. By selecting this OEM component, engineers secure backward compatibility across multiple equipment generations, reducing downtime during system redesigns and supporting scalable production lines.
