In the rigid architecture of black iron or stainless steel discharge piping, the 16901 provides the mechanical agility required to bridge the gap between fixed infrastructure and dynamic hazard zones. Rated for a full 360-degree rotation, this 3\/8\" NPT swivel is the definitive component for ensuring that discharge nozzles are not just installed, but mathematically aimed to stop a fire at its source.\u003c\/p\u003e\n        \u003cp\u003eThe 16901 is the strategic solution to the fixed-thread dilemma. Because standard pipe threads lock at a specific torque, a nozzle without a swivel is often held hostage by the final orientation of the pipe run. The Amerex 16901 breaks this limitation, allowing for post-installation adjustments that satisfy rigorous UL 300 nozzle alignment mandates. Utilizing the genuine Amerex OEM swivel ensures your facility maintains its safety listing and provides the directional precision to suppress grease fires before they reach the exhaust ductwork.\u003c\/p\u003e\n\n        \u003ch3\u003e360-Degree Radial Adjustment\u003c\/h3\u003e\n        \u003cp\u003eThe 16901 allows for infinite 360-degree radial adjustment. The target center of an appliance can shift during kitchen remodels or routine maintenance. The swivel allows a technician to re-center the nozzle's cone of suppression without re-threading the manifold, maintaining a constant state of fire readiness.\u003c\/p\u003e\n\n        \u003ch3\u003eHydraulic Surge Integrity\u003c\/h3\u003e\n        \u003cp\u003eDuring system actuation, the wet chemical agent is propelled through the piping at high velocity. The 16901 is engineered to maintain its aim under these pressure transients, ensuring the discharge surge does not cause the swivel to whip or shift. The internal friction of the joint is balanced to hold position against the hydraulic forces generated during discharge.\u003c\/p\u003e\n\n        \u003ch3\u003eInterference-Fit Sealing\u003c\/h3\u003e\n        \u003cp\u003eThe swivel utilizes a precision-machined internal junction with high-temperature O-rings to prevent agent leakage. This ensures the pressure intended for the nozzle orifice is not bled off at the joint, maintaining the factory-rated discharge velocity required for rapid flame knockdown.\u003c\/p\u003e\n\n        \u003ch3\u003eNickel-Chrome Plated Brass Construction\u003c\/h3\u003e\n        \u003cp\u003eKitchen exhaust environments are chemically aggressive. The 16901's nickel-chrome plated brass finish resists the pitting corrosion caused by aerosolized salts and caustic degreasers, preventing the swivel from seizing or galling over years of service in a grease-laden plenum.\u003c\/p\u003e\n\n        \u003ch3\u003eFacilitating NFPA 17A Compliance\u003c\/h3\u003e\n        \u003cp\u003eUnder NFPA 17A, every semi-annual inspection must verify nozzle alignment. The 16901 transforms this from a plumbing task into a calibration task. A technician can loosen the swivel, verify the aim against the manufacturer's aiming chart, and re-secure it in minutes, ensuring the facility remains in full legal and insurance standing.\u003c\/p\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 2: Applications \u0026 Use Cases --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eApplications \u0026amp; Use Cases\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003cul\u003e\n          \u003cli\u003e\n\u003cstrong\u003eIndustrial Fryer Lines:\u003c\/strong\u003e Allowing for precise aiming over deep-vat fryers where oil splashing must be minimized.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eCharbroiler Stations:\u003c\/strong\u003e Ensuring the agent penetrates the rising heat plume of lava rock or mesquite grills.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eDuct and Plenum Protection:\u003c\/strong\u003e Providing a pivot point for nozzles protecting the entry points of exhaust ductwork.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eInstitutional Kitchens:\u003c\/strong\u003e Maintaining code compliance in facilities with high-volume, 24\/7 cooking cycles.\u003c\/li\u003e\n          \u003cli\u003e\n\u003cstrong\u003eCommercial Kitchen Suppression Manifolds:\u003c\/strong\u003e Standard inventory item for contractors managing large-scale facility fleets requiring precise nozzle positioning in dense appliance configurations.\u003c\/li\u003e\n        \u003c\/ul\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 3: Technical Specifications --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eTechnical Specifications\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ctable class=\"specs-table\"\u003e\n          \u003cthead\u003e\n            \u003ctr\u003e\n              \u003cth\u003eFeature\u003c\/th\u003e\n              \u003cth\u003eDetails\u003c\/th\u003e\n            \u003c\/tr\u003e\n          \u003c\/thead\u003e\n          \u003ctbody\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eManufacturer\u003c\/td\u003e\n              \u003ctd\u003eAmerex Corporation\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003ePart Number\u003c\/td\u003e\n              \u003ctd\u003e16901\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eThread Size\u003c\/td\u003e\n              \u003ctd\u003e3\/8\" NPT (Male x Female)\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eRotation\u003c\/td\u003e\n              \u003ctd\u003e360-Degree Radial Adjustment\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eMaterial\u003c\/td\u003e\n              \u003ctd\u003eNickel-Chrome Plated Brass\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n              \u003ctd\u003eAmerex KP Series\u003c\/td\u003e\n            \u003c\/tr\u003e\n            \u003ctr\u003e\n              \u003ctd\u003eCertifications\u003c\/td\u003e\n              \u003ctd\u003eUL Listed, ULC Listed\u003c\/td\u003e\n            \u003c\/tr\u003e\n          \u003c\/tbody\u003e\n        \u003c\/table\u003e\n      \u003c\/div\u003e\n    \u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003c!-- Section 4: Installation \u0026 Compliance --\u003e\n  \u003cdiv class=\"accordion-item\"\u003e\n    \u003cbutton class=\"accordion-header\"\u003e\n      \u003cspan class=\"accordion-title\"\u003eInstallation \u0026amp; Compliance\u003c\/span\u003e\n      \u003cspan class=\"accordion-icon\"\u003e⌄\u003c\/span\u003e\n    \u003c\/button\u003e\n    \u003cdiv class=\"accordion-content\"\u003e\n      \u003cdiv class=\"accordion-content-inner\"\u003e\n        \u003ch3\u003eThe Wrench-Tight Rule\u003c\/h3\u003e\n        \u003cp\u003eDuring installation, the swivel should be wrenched onto the kitchen suppression manifold to a liquid-tight standard.
