$10.42The Graco 101530 Screw Cap is a precision-machined closure component engineered for robust fluid containment in high-pressure environments. Measuring 1.2 inches in height, length, and width, it nests into reservoirs with an overall volumetric footprint of just 0.001 ft³ (0.000 m³). Designed to interface seamlessly with modern airless sprayer platforms, this cap maintains consistent seal integrity under pressures exceeding 5000 psi, directly contributing to enhanced pump efficiency and extended seal longevity. Its compact geometry minimizes dead zones and supports professional coatings applications, ensuring reliable fluid isolation in demanding industrial spray systems.
Thoroughly optimized for integration with graco paint sprayer gun parts, the cap’s internal thread form features a 60° V-profile with a 1.5 mm pitch, delivering uniform axial preload and uniform sealing forces. The sealing face incorporates a polished ledge with a concentric O-ring groove machined to ±0.02 mm flatness, supporting high-pressure filtration without compromising flow paths. Surface roughness on the contact faces is held below RA 0.4 µm, reducing leak channels and enhancing seal longevity in continuous-cycle industrial applications.
Constructed from AISI 316 stainless steel, the 101530 cap is selected for its superior corrosion resistance and mechanical strength. Nickel-chrome passivation adds a 25 µm barrier against chloride-induced pitting while maintaining hardness levels of 220–240 HV on the Vickers scale for wear resistance. The component endures temperatures from –20 °C to +120 °C without compromising structural integrity, making it ideal for both hot solvent and cold water systems. Precision CNC turning and subsequent electropolishing guarantee chemical inertness and support continuous high-pressure filtration in automated spray lines.
Widely used in industrial paint delivery circuits, the 101530 Screw Cap interfaces with piston-packaged pumps, diaphragm modules, and gravity-feed manifolds in airless sprayer configurations. It is fully compatible with standard Graco spray gun adapters and manifold plates, facilitating rapid system swaps and reducing downtime. Technicians often source this cap alongside graco pump repair kits to perform comprehensive maintenance, ensuring that critical fluid passages remain free of debris and that pump efficiency is restored to factory specifications after each service interval.
Field testing demonstrates leak-free operation up to 5000 psi of static pressure and cyclic endurance exceeding 10,000 actuation cycles. The cap’s mechanical retention torque is calibrated at 15–20 Nm, delivering a reliable clamp load without overstressing the thread form. High-pressure filtration trials show particulate ingress below 2 µm when used with micron-rated filter cartridges upstream. Seal longevity trials indicate minimal volumetric loss (<0.05 ml/week) in continuous operation, validating the precision engineering and consistent performance required for professional coatings deployments.
Routine maintenance involves disassembly using a 14 mm hex socket, inspection of the O-ring groove, and cleaning of the thread flank using a non-aggressive solvent. When combined with standard graco repair kits, operators can replace sealing elements, refresh filtration modules, and recondition mating surfaces in under 10 minutes. Lubrication with FDA-approved silicone grease preserves seal longevity and aids in torque control. Regular high-pressure filtration replacement upstream ensures that abrasive wear on the cap’s contact faces remains minimal, extending mean time between repairs.
For correct assembly, align the cap by hand until full thread engagement is achieved, then apply a calibrated torque wrench set to 18 Nm to seat the seal. Avoid cross-threading by ensuring concentric alignment within 0.2 mm radial runout. Use a non-hardening thread sealant sparingly to prevent cold welding in stainless-steel components. Final inspection should verify that the mating surface displays a continuous 360° seal line without gaps or deformation before pressurization.
The Graco 101530 Screw Cap exemplifies precision engineering for modern fluid control systems. Its compact footprint, combined with stringent material selection and tight tolerances, delivers unmatched reliability in airless sprayer assemblies and professional coatings applications. By optimizing pump efficiency, supporting high-pressure filtration, and maximizing seal longevity, this component underpins the performance of demanding industrial spray operations and contributes to long-term system uptime.
