$7.25Graco 15C990 gland packing rings represent a critical sealing solution for fluid control pumps in industrial finishing and surface preparation systems. Engineered to maintain optimal pressure barriers, these packing rings are tailored for robust service in diaphragm and piston pump assemblies. The multi-layered composition combines braided fibers impregnated with specialized lubrication compounds to ensure minimal friction and extended service cycles. Suitable for integration with high-viscosity media, the 15C990 delivers consistent performance in demanding spray applications, especially when paired with an airless sprayer. This packing adapts seamlessly to various pump styles, enhancing overall system reliability in professional coatings workflows.
Constructed with a proprietary blend of PTFE, aramid, and graphite strands, the Graco 15C990 gland packing offers a unique balance of compressibility and tensile strength. The engineered fiber matrix is impregnated with corrosion inhibitors and lubricants to minimize wear during reciprocating motions. This material synergy ensures compatibility with industrial solvents and a wide pH range, making it ideal for various professional coatings processes. Engineers appreciate the consistent compression set that prolongs maintenance intervals and reduces system downtime. Built to withstand abrasive particulates, the packing supports high-pressure filtration processes without compromising seal integrity. Applications include pump seals in high-demand water treatment and chemical dosing systems.
Laboratory and field evaluations quantify the 15C990 gland packing’s performance under cyclic loading and elevated temperatures. Pressure endurance tests confirm sealing stability at up to 5000 psi, with minimal extrusion. Friction coefficients remain below 0.08, ensuring predictable torque requirements for gland nuts. Long-duration trials demonstrate reliable seal operation for over 2000 hours, reflecting excellent high-pressure filtration compatibility and particulate retention. In applications such as spray finishing lines or metering pumps, the packing maintains low leakage rates and supports accurate fluid delivery without increasing maintenance demands. Its consistent performance under both reciprocating and rotary motion makes it suitable for diverse pump configurations, enhancing operational predictability in industrial fluid management.
Each 15C990 ring is braised to a precise cross-sectional profile, facilitating predictable compression and alignment within the stuffing box. The braid features a dual-core design surrounded by a PTFE layer, optimizing lubrication distribution and thermal dissipation. CNC-cut edges maintain dimensional repeatability within ±0.02 mm tolerances, matching OEM shaft and housing geometries for seamless retrofitting. This architecture promotes uniform sealing forces around the shaft, reducing localized wear and vibration. Standard gland nut torque values apply, enabling quick setup with minimal adjustment, and ensuring consistent performance across various pump models. The uniform braid geometry also aids in heat dispersion, preventing hotspots during high-cycle operations.
Proper installation of the 15C990 packing begins with shaft surface inspection to ensure concentricity and absence of scoring. Clean the stuffing box thoroughly, then stack the rings with staggered joint placement to prevent leakage paths. Apply a thin film of grease or a compatible liquid lubricant to each ring face, reducing break-in friction. Tighten the gland nut incrementally in quarter-turn steps, monitoring torque levels to achieve the correct compression. After the initial run-in period, verify temperature stabilization and perform a final re-torque. Following these guidelines maximizes seal longevity and maintains pump efficiency, reducing maintenance cycles and operational costs.
For optimal service life, the 15C990 gland packing operates reliably between -40 °C and 260 °C, accommodating both cryogenic and elevated-temperature tasks. It tolerates hydraulic fluids, acids, alkalis, and most solvent-based coatings with stable dimensional behavior. The packing sustains static pressures up to 5000 psi and dynamic pressures to 3000 psi in reciprocating and rotary pump applications. Periodic inspection of gland torque and ring alignment is recommended to maintain sealing performance. Adherence to torque specifications prevents over-compression and extends maintenance intervals, aligning with safety protocols and industry best practices. Chemically inert packing composition ensures minimal interactions with pigment dispersions and enhances long-term performance in paint circulation systems.
By integrating the Graco 15C990 gland packing into your fluid delivery systems, maintenance teams and design engineers can achieve superior sealing performance and reduced downtime. The robust material construction and tight manufacturing tolerances ensure compatibility with a wide array of industrial media, from high-solids resins to abrasive polymer dispersions. Thoughtful design features deliver consistent compression set and minimal wear rates, driving higher pump efficiency and reliable cycle counts. Whether employed in high-volume production lines or precision coating applications, this packing ring offers the durability and performance required for modern engineering challenges, elevating operational standards and equipment longevity.
