$1163.48Graco 181890 Plate, Tie stands out as a precision-engineered mounting bracket designed specifically for high-performance fluid handling systems. This component secures critical pump assemblies in place, minimizing vibration and misalignment during operation. Crafted to interface seamlessly with Graco’s series of piston pumps, the tie plate ensures consistent stroke alignment and extends overall system life by reducing wear on moving parts. Maintenance crews and equipment specialists value its robust build, ensuring that each service interval runs smoothly and without unexpected downtime.
Precision manufacturing lies at the heart of this plate tie’s design. CNC-machined from high-strength aluminum alloy, it exhibits tight tolerances that guarantee a perfect interface with adjacent components. A series of counterbored mounting holes facilitates flush screw installation, while integrated reinforcing ribs deliver enhanced rigidity under cyclic loading. Its surface finish resists abrasion and chemical attack, critical when working near solvents or paints. By optimizing the geometric profile, engineers have reduced stress concentrations and improved fatigue resistance over traditional flat plate solutions.
Integration with existing pump modules is straightforward thanks to universal hole spacing and thread specification. Compatibility extends across Graco’s lineup of piston and diaphragm pumps without requiring custom adapters. Operators can swap out worn plates quickly, reducing downtime and labor costs. This tailor-made tie plate pairs well with a variety of graco sprayer accessories, offering a modular approach that adapts to changing production and finish requirements in industrial settings. Rigorous quality checks ensure that each unit meets performance benchmarks before leaving the factory.
Installation demands minimal tooling: a torque-rated wrench and Loctite-grade sealant will suffice. Begin by aligning the plate’s dowel pins with the pump housing slots, then hand-thread fasteners to preserve the anodized finish. Final torque values fall within the pump manual’s recommended range. Technicians should inspect mounting surfaces for burrs or old sealant residue before assembly. Periodic checks during scheduled maintenance cycles will confirm that no loosening has occurred. Replacement intervals should coincide with inspection of adjacent graco pump parts, ensuring all components perform optimally under pressurized conditions.
Repeated pressure cycles can induce fatigue in even the sturdiest alloys, but this plate tie features stress-relief geometries to counteract that effect. Finite element analysis validated the design under simulated worst-case scenarios, including rapid load reversals and thermal variations. Its anodized finish further enhances surface hardness, protecting against micro-abrasion from entrained particulates in fluid streams. Many field reports highlight operational lifespans exceeding 10,000 hours before a simple re-torque or inspection is required, outperforming comparable aftermarket kits by a significant margin.
Key dimensions include a 6.75-inch overall length, 2.50-inch width, and 0.375-inch thickness. Hole pattern matches industry-standard 0.188-inch tapped threads on 1/4-20 UNC fasteners. Weight clocks in at just under 1.2 pounds, balancing structural integrity with manageable handling during installation. Operating temperature range spans -40°F to 250°F, accommodating most solvent- and chemical-based fluids. Finish tolerances adhere to ISO 2768-m standards, which guarantees consistency across multiple production batches.
Maintenance teams in agriculture, automotive painting, and heavy industry often rely on this plate tie when refurbishing older pump assemblies. Customized retrofit kits that include this component bring legacy equipment up to modern performance standards. Integration into portable spray rigs and stationary coating systems alike highlights its versatility. Field service bulletins have documented simple upgrades that cut vibration-induced seal failures by over 30%. A well-stocked parts cabinet should contain this tie alongside a graco gun repair kit, ensuring swift resolution to any component wear issues.
Engineered for professionals who demand reliability, Graco 181890 Plate, Tie combines precision machining with rugged materials to support critical pump assemblies. Its design optimizes both installation ease and long-term durability while aligning with industry-standard mounting protocols. For ongoing performance, follow OEM guidelines and incorporate regular inspections into your preventive maintenance schedule. Consult Graco’s technical support or authorized service centers for OEM replacement parts and expert advice to ensure seamless operation and extended equipment life.
