$6.3The Graco 112600 Spring Lock Washer is a precision-engineered locking element designed to maintain axial tension in high-vibration assemblies common to industrial pump systems and fluid delivery modules. Manufactured from spring-tempered steel with a robust protective finish, it ensures consistent preload retention in applications ranging from airless sprayer manifolds to high-performance coating circuits. Part of Graco’s MISC family code with a Taiwanese origin, this washer features a height of 0.25 inches and an outer diameter of 0.625 inches, optimized for insertion beneath hexagonal nuts or flange heads. It supports advanced professional coatings equipment requiring repeatable clamping forces and improved wear resistance.
In precision fluid handling systems, the Graco 112600 washer plays a pivotal role in safeguarding clamped junctions from loosening under dynamic loads. Its conical spring profile applies uniform radial pressure, countering torsional back-off in gear pumps and piston assemblies. When integrated with a magnum x5 paint sprayer, the component contributes to enhanced pump efficiency by stabilizing manifold interfaces and reducing micro-leaks. Its calibrated spring rate aligns with nominal bolt tensions, ensuring optimal preload in air-operated diaphragm units and high-speed rotary couplers. Its corrosion-resistant plating also complements seal longevity in aggressive media environments, making it suitable for prolonged maintenance cycles in spray and pumping rigs.
Installation of the spring lock washer requires minimal torque calibration tools, enabling precise control over clamp load, critical in robotics actuator mounts and sealing manifolds. The minimal installation height permits compact assembly in low-profile designs without compromising locking effectiveness. Engineers benefit from the washer’s symmetrical split design that distributes stress uniformly around bolt shanks, mitigating fretting corrosion. Routine inspection protocols involve verifying axial displacement and spring tension, ensuring that the washer’s performance adheres to specified torque retention thresholds. When paired with automated torque wrenches, this washer ensures consistent preload across hundreds of identical fastened joints.
The Graco 112600 Spring Lock Washer is fabricated from C1045 spring steel, selected for its high yield strength and fatigue resistance under cyclic loading. Heat-treated to a Rockwell C45 hardness, the washer exhibits a calibrated spring rate optimized for joint preload and energy dissipation. Its Zinc dichromate plating not only protects the substrate from corrosion but also minimizes surface friction during nut rotation. In fluid dispensing applications such as the graco x7 airless paint sprayer, this washer’s dimensional tolerances and metallurgical consistency ensure uniform clamp forces and eliminate torque loss due to material creep or relaxation. Manufacturing traceability is maintained through laser-etched batch codes, facilitating quality assurance and compliance with industrial safety standards.
Extensive cycle testing under variable load spectrums confirms the washer’s capacity to withstand over 10,000 engagement cycles without significant loss of spring tension. Dynamic torque evaluations indicate less than 5% preload deviation across temperature ranges from -40°C to 120°C, ensuring reliability in thermal cycling environments. In systems requiring high-pressure filtration of abrasive media, the lock washer prevents fastener back-off that could compromise filter housings. Fatigue life analyses, coupled with salt spray exposure tests, validate the component’s endurance in corrosive environments, establishing it as a preferred choice for mission-critical coating and fluid delivery assemblies. Combined with rigorous dimensional inspection, these metrics underpin consistent joint integrity over extensive service intervals.
Technicians installing the Graco 112600 washer benefit from straightforward integration into existing fastener workflows, eliminating the need for specialized locking adhesives or retorque cycles. The washer is compatible with standard ISO 4014 and 4017 hex bolts, supporting quick-change tasks in mobile and fixed spray rigs. When deployed in hplv paint guns, it stabilizes the fluid path pressure regulators, reducing fluctuation during trigger modulation. Its ability to maintain axial tension reduces downtime for retightening, streamlining preventive maintenance schedules and enhancing overall equipment effectiveness in field applications. Periodic inspection intervals align with hydraulic fluid change-out routines, allowing simultaneous verification of spring tension.
The compact form factor and robust mechanical architecture of the Graco 112600 Spring Lock Washer make it indispensable across a spectrum of fluid control and coating delivery systems. Its precision-manufactured contours and validated fatigue life translate into reduced maintenance overhead and heightened system uptime. Engineers designing high-pressure manifolds, filtration modules, or mobile spray platforms will find consistent preload retention critical for preventing component loosening and leak paths. With traceable batch identification and compliance to industry torque retention standards, this lock washer elevates assembly integrity and serves as a foundational element in high-demand industrial solutions. Its versatility underpins long-term operational resilience.
