$6.3The Graco 15C871 Leg Cap is a precision-engineered component designed for integration into high-pressure fluid handling systems. Manufactured with exacting tolerances, this leg cap serves as an end closure for the pump leg assembly, ensuring consistent alignment and structural reinforcement within the pump housing. At just 1.8 x 1.7 x 1.7 inches and weighing only 0.05 pounds, the compact footprint optimizes system packaging while minimizing inert mass. Its seamless interface with adjacent modules makes it suitable for applications demanding robust sealing and precise fluid routing. Technical professionals often specify this component when customizing insulated supply lines or compact spray modules around a compact core.
Crafted from a high-grade engineering thermoplastic, the Graco 15C871 Leg Cap utilizes chemical-resistant acetal copolymer to withstand aggressive solvents and diverse coating formulations. The intrinsic rigidity of the polymer ensures dimensional stability under cyclic pressure loads, while its low friction coefficient reduces wear on adjacent seals and moving parts. Material certification meets ASTM D6779 standards for plastic components in fluid handling assemblies, guaranteeing traceability and compliance. The precision injection molding process maintains a surface finish below 32 microinches Ra, facilitating an unobstructed fluid path in air-assisted and airless sprayer designs. Post-molding annealing further relieves internal stresses and optimizes thermal performance up to 80 °C.
In rigorous bench testing, the Graco 15C871 Leg Cap demonstrates pressure resilience up to 5000 psi, aligning with pump head specifications in high-demand commercial painting systems. Leak tests performed according to ISO 9001 protocols confirm zero seepage through the cap-to-leg interface over extended duty cycles. The tolerances held in the injection-molded part are ±0.05 mm, ensuring repeatable assembly alignment and minimal flow disruption. Corrosion resistance has been validated after exposure to alkyds, polyurethanes, and professional coatings solvents, maintaining structural integrity and dimensional fidelity. Thermal cycling between –20 °C and 80 °C shows negligible deformation, underscoring the component’s suitability for temperate and elevated temperature operations.
The geometric profile of the leg cap incorporates a radiused corner feature where the cylindrical skirt meets the flanged top surface, reducing stress concentration under dynamic loads. CNC-controlled molds produce consistent wall thicknesses of 1.2 mm, which contribute to predictable elastic deformation patterns and maintain seal compression force. The internal bore diameter holds a tolerance of +0.02/–0.00 mm to facilitate interference fit with the mating pump leg tube. Edge chamfers at 0.25 mm ease installation and prevent sharp transitions that could impair high-pressure filtration paths. This attention to detail in design ensures flawless integration with multi-component pump subassemblies.
In industrial spray operations, the 15C871 Leg Cap is often deployed in inline pump designs that support consistent fluid delivery in automotive refinish and architectural coating setups. Its stable register within the fluid circuit contributes to optimal pump efficiency and reduced pulsation, which downstream regulators leverage for consistent outlet pressure. Pairing this cap with a precision-engineered piston or diaphragm pump facilitates smooth reciprocation against seals, extending service intervals. Integration into closed-loop solvent reclamation modules demonstrates its versatility, where leak-proof performance under vacuum and back pressure conditions is critical for system integrity. Regular inspection of the cap-to-leg junction helps monitor seal longevity and predictive maintenance schedules in high-throughput operations.
Maintenance procedures recommend disassembly of the pump housing and cap at scheduled intervals, allowing thorough cleaning of the internal bore and flange surfaces. Use of non-abrasive cleaners preserves the polymer’s microfinish, preventing micro-scratches that could harbor coating residues or contaminants. Technicians implementing rapid interchange routines benefit from the cap’s tapered lead-in, which enables tool-less seating and removal with minimal motion. For retrofit scenarios, adapters available in complementary sizes allow the Graco 15C871 Leg Cap to support both legacy and current model sprayers without compromising flow characteristics. This flexibility streamlines inventory management and reduces downtime during changeover.
Engineers specifying components for advanced coating systems will find the Graco 15C871 Leg Cap to be a robust solution that enhances system reliability and performance. Its precise manufacturing aligns with rigorous industry benchmarks for fluid control, including consistent flow rates and stable pressure profiles. The cap’s material chemistry and design geometry collaborate to minimize wear and extend service life, reducing overall maintenance costs. Whether integrated into high-throughput conveyors or portable spray rigs, this leg cap contributes to seamless operations within demanding industrial environments.
