$15.59The Graco 101714 lock nut is a precision-engineered retaining component designed for robust performance within high-pressure spray circuits. Manufactured from hardened stainless steel with tight tolerances down to micrometer-level diameter variance, it provides secure engagement between manifold unions and drive pumps. Its surface treatment enhances corrosion resistance and promotes consistent torque response in aggressive chemical environments. This nut seamlessly integrates with airless paint sprayer attachments while supporting seamless mounting on fluid delivery heads and facilitating rapid assembly cycles in enclosed systems.
In performance testing against legacy lock nuts, the 101714 design demonstrated a 25% improvement in clamp retention under cyclical vibration loads, thanks in part to its advanced thread profile geometry. Incorporating proprietary surface roughness patterns, this component ensures consistent preload across repetitive installation cycles and contributes to enhanced graco spray gun accessories modularity. Engineers report measurable gains in pump efficiency when integrating the lock nut in reciprocating piston and diaphragm pump assemblies used for solvent-borne and waterborne coatings.
The lock nut’s thread pitch and flank angle have been optimized using finite element analysis (FEA) to balance elastic deformation and preload distribution. With a family classification under FAMX™ and manufactured in Graco Industrial’s CED division, it aligns with ISO 5459 dimensional standards for interchangeable fastening elements. The nut’s material specification exhibits yield strength above 850 MPa and maintains hardness in the HRC 38–42 range after heat treatment. Such characteristics are essential when performing fluid delivery in professional coatings applications, particularly with 2K reactive resins and abrasive filler materials.
Rigorous accelerated life testing under thermal cycling between –20 °C and 80 °C ensures the 101714 maintains retention torque within ±5% of initial clamp values. Sealing performance is validated via helium leak detection to PPM-level thresholds, upholding system integrity under high differential pressures. Specialized plating resists galling even under repetitive assembly exceeding 5,000 cycles, a key factor in extending seal longevity in continuous operation. High-pressure filtration modules benefit from the nut’s ability to prevent micro-shifts that can compromise filter media alignment and backpressure consistency.
Proper installation begins with cleaning mating threads to remove residual debris and applying a thin, non-migratory lubricant. Use a calibrated torque wrench to apply the recommended 16 Nm tightening specification, verifying against manufacturer calibration charts for thread engagement depth. Bearings and shaft housings can be assembled in either vertical or horizontal orientations without altering torque parameters. The nut’s chamfered lead-in feature simplifies start-up on misaligned studs, minimizing cross-thread risk during maintenance interventions.
When installed within manifold headers or pump inlet assemblies, the 101714 lock nut interfaces with standard Graco couplers, ensuring leak-free junctions under 3,000 psi (207 bar) operating pressures. Its design supports compatibility with pneumatic-hydraulic actuators used in automated fluid dispensing cells. System architects leverage its compact envelope to conserve space within block-mounted valve banks and ensure predictable flow distribution in multi-zone cartridges. This locking element enhances the reliability of an airless sprayer network, preventing loosening events during high-cycle production runs.
Periodic inspection should include torque verification and visual checks for surface wear or plating degradation. Replace the nut at recommended intervals aligned with pump service schedules to maintain optimum preload and thread integrity. Since it is engineered as a core component among genuine Graco parts, this lock nut aligns with OEM guidelines for preventative maintenance. Engineers can track service history via serial number stamping on the nut’s hex face, ensuring traceability in quality control documentation.
Beyond its primary retention role, the 101714 lock nut contributes to dynamic response management in reciprocating circuits. By stabilizing axial preload, it reduces pulsation amplitude transmitted to downstream valves and filters. Computational fluid dynamics (CFD) models confirm that thread engagement uniformity is critical to minimizing flow impedance under high-frequency cycles. This uniform preload distribution also directly impacts component fatigue life, supporting extended maintenance intervals in continuous industrial painting lines.
The Graco 101714 lock nut functions as a vital mechanical safeguard in high-performance spraying equipment. Its advanced metallurgy and precision geometry support consistent performance across harsh industrial environments, from solvent-laden coatings to abrasive media pumping. By integrating seamlessly into pump heads, manifold blocks, and filter housings, it underpins critical operational metrics such as flow stability, pump efficiency, and system uptime. When selecting locking fasteners for professional finishing and coating processes, the 101714 offers unmatched reliability and endurance under demanding conditions.
