$9.88The Graco 100184 Hex Hd Screw Cap is a precision-engineered fastening component designed for high-pressure fluid systems in industrial coatings delivery modules. Manufactured to exacting tolerances, this screw cap features a robust hex head profile that ensures secure engagement with torque wrenches and reduces cam-out during installation and removal. At 1.2 in (3.048 cm) in both length and width, the part integrates seamlessly into manifold assemblies and valve covers, serving as both a mechanical seal and a service port closure. Engineered for compatibility with modern Graco manuals and calibrated torque tools, this cap plays a pivotal role in maintaining optimal system integrity in an airless sprayer environment.
Fabricated from premium corrosion-resistant alloy steel, the 100184 Screw Cap undergoes multiple surface treatments—including zinc electroplating and passivation—to withstand aggressive solvent-borne and waterborne chemistries. This material selection maximizes resistance to galling and micro-welding under cyclic pressure fluctuations while preserving critical tolerances. Precision machining ensures consistent thread engagement in high-pressure filtration zones, minimizing unwanted bypass and maintaining pump efficiency. When cross-referencing the Graco assembly BOM in the graco parts list, technicians will note its role in sealing critical leak paths within pressure-regulating manifolds.
The hex head geometry of this cap has been optimized via finite element analysis (FEA) to distribute installation torque evenly across bearing surfaces, reducing stress concentrations at the head–shank junction. Its chamfered lead-in and radiused root undercut simplify thread start and prevent damage to mating components. Designed to interface with high-tension O-rings or PTFE seals, it enhances overall seal longevity by applying uniform compression. Field technicians working on graco sprayers report improved disassembly speed without compromising system pressure ratings, underscoring its contribution to reduced downtime and consistent pump performance.
Rigorous testing protocols subject the 100184 cap to over one million installation cycles, evaluating torque retention, thread wear, and resistance to vibration-induced loosening. Typical yield strength exceeds 100 ksi, with a tensile rating above 120 ksi, ensuring structural integrity in professional coatings applications. This fastener has been validated under pressures up to 5,000 psi, confirming its ability to maintain fluid separation in critical filtration stages without deformation. Integration of specialized professional coatings on external surfaces further bolsters resistance to abrasion and chemical attack, extending service intervals in abrasive pigment-laden environments.
Incorporation of this Hex Hd Screw Cap within Graco pump modules enhances modular repairability, enabling precise access to internal seals and pistons. The head’s 6 mm hex socket interface supports the use of high-angle impact drivers or torque-limiting bits, facilitating controlled tensioning. Engineers leverage this design to streamline routine seal replacement, leveraging calibrated audits of preload torque to safeguard system performance. Its compatibility with high-flow seal kits and advanced filtration cartridges makes it indispensable in both plural-component mixing and single-component dispersion setups.
Preventative maintenance for the 100184 cap involves periodic inspection of thread integrity and head face wear, especially after extended operation in abrasive or high-temperature conditions. Recommended protocols include cleaning thread crevices with a non-reactive solvent and applying a thin film of anti-seize compound to prevent cold welding. Torque specifications typically range between 80–100 in-lb, depending on seal material hardness and module design parameters. Adhering to these practices preserves clamp load consistency and prolongs overall system reliability.
When integrated into complete fluid delivery assemblies, the Graco 100184 Hex Hd Screw Cap plays a critical role in maintaining optimal pressure regulation, preventing contaminants from breaching pump internals, and ensuring precision flow control. Its compact geometry and standardized interface enable compatibility across a range of Graco pump series and accessory manifolds. By coupling this cap with high-temperature O-rings and advanced filter media, system designers achieve a balanced combination of chemical resistance, vibration damping, and repeatable sealing performance—key factors for mission-critical industrial spraying operations.
