Graco’s 188940 Adapter, Bung revolutionizes fluid handling by offering secure, leak-free connections between your pump and container. Designed to simplify pressurized dispensing systems, this adapter integrates seamlessly into industrial fluid management workflows to ensure reliable performance across diverse environments. Technicians and applicators appreciate its robust construction, precise threading, and broad compatibility, enabling consistent fluid flow without frequent downtime for adjustments or repairs.
High-strength aluminum alloy forms the backbone of this adapter, delivering exceptional resistance to solvent exposure and mechanical stress. Achieving an ideal balance of weight and durability, grains in the metal are refined through anodizing to enhance surface hardness and wear resistance. Special consideration has been given to thread tolerances, resulting in precision engagement that mitigates the risk of leaks under high-pressure loads.
Widely compatible with leading pumping systems, this adapter connects effortlessly to piston, diaphragm, and rotary vane pumps. Professionals who rely on spray finishing have found it particularly effective when calibrated with a hvlp paint spray gun, eliminating the need for custom fittings. Integration with existing gear occurs smoothly, reducing conversion costs and complexity.
Follow a straightforward procedure to install the bung adapter into standard drums or pails. Begin by cleaning the flange to remove contaminants, then hand-thread the adapter until snug. A final quarter-turn with a torque tool ensures a proper seal, typically between 20 and 25 ft-lb. Avoid over-tightening, which may compromise the thread integrity or distort gaskets. Confirm that any integrated venting ports remain unobstructed to allow pressure equalization during dispensing. Regular inspection for signs of seal wear or thread damage helps maintain flawless performance and prevents downtime.
Routine checks for thread integrity and gasket condition will extend service life significantly. In harsh chemical environments, periodic rinsing with compatible solvents can prevent buildup that impedes sealing surfaces. Proper lubrication of adjacent seals and periodic thread cleaning using appropriate solvents will further prolong service intervals. Replacement of O-rings or sealing elements at recommended intervals ensures uninterrupted operations. Replacement kits comprising multiple O-rings, backup rings, and sealing caps are available for preventative stock. Adhering to a preventive maintenance schedule reduces the likelihood of unscheduled stoppages.
Integrating this adapter into production lines can enhance throughput by minimizing fluid transfer interruptions. Balanced flow rates maintain consistent spray patterns, which helps in paint, adhesive, and lubricant applications. Customers have noted improved accuracy when pairing their systems with hplv paint guns, underscoring the adapter’s role in achieving uniform coatings with minimal overspray.
Crafted from anodized aluminum, this adapter offers excellent tolerance to solvents and acidic compounds common in coating and adhesive workflows. Anodization increases surface hardness, resisting abrasion and chemical etching that can compromise seals. For applications involving aggressive media, nitrile or Viton O-ring options are available to ensure compatibility. Temperature fluctuations from ambient to elevated ranges will not degrade the structural integrity, while its corrosion-resistant finish prevents pitting that could lead to leakage.
Beyond standard paint and lubricant systems, this adapter finds use in food-grade fluids, chemical processing, and pharmaceutical batching. Clean-in-place procedures become more efficient due to smooth internal passages that discourage residue build-up. Custom gasket compounds meet FDA or NSF requirements, enabling trouble-free transitions between viscous materials or low-viscosity solvents. Field service teams often recommend this component when retrofitting older dispense units to modern safety and hygiene guidelines.
Specialist workshops emphasize the importance of sourcing genuine replacement parts and accessories. Pair this adapter with advanced pump controllers and filtration systems for optimal outcomes. Upgrades such as quick-disconnect couplings and pressure regulators can further streamline workflow. Owners of equipment like the graco ultra 395 will appreciate how this adapter maintains peak system integrity under demanding conditions.
