Precision machined from high-grade brass and surrounded by a protective aluminum shroud, the ns-uni installs with a single screw-on motion and can only be removed with a special proprietary tool. This dual-layer construction prevents unauthorized access, deters refrigerant theft, and reduces the risk of accidental refrigerant mixing. HVAC technicians install these caps as a code-compliance and environmental safeguard on residential and light commercial systems.\u003c\/p\u003e\n\u003cp\u003eThe ns-uni is suited for use on central AC systems and mini-splits where Schrader service valves are present. It is commonly installed by licensed HVAC technicians during routine service calls, equipment commissioning, or whenever a system is left unattended for an extended period. The locking design helps prevent refrigerant loss to the atmosphere and reduces the risk of injury to children or untrained individuals who might otherwise access live refrigerant service ports. Sold as a single cap.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision machined brass construction with protective aluminum shroud for durability and tamper resistance\u003c\/li\u003e\n  \u003cli\u003ePatented locking design requires a special tool for installation and removal\u003c\/li\u003e\n  \u003cli\u003eSingle screw-on installation for fast field use\u003c\/li\u003e\n  \u003cli\u003eSeals standard Schrader service valves to prevent refrigerant leakage and accidental mixing of refrigerant gases\u003c\/li\u003e\n  \u003cli\u003eHelps protect against injury or death from inhalation of dangerous refrigerants\u003c\/li\u003e\n  \u003cli\u003eCompatible with central AC units and mini-split systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal-fit locking cap for standard 1\/4 inch Schrader service valves found on central air conditioning units and mini-split systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal require the NOVENT proprietary tool — do not attempt installation or removal with standard valve core tools or pliers. Always recover or isolate refrigerant per EPA Section 608 requirements before servicing the valve. HVAC technicians should verify valve threads are clean and free of debris before seating the cap. This work is typically performed by EPA 608-certified refrigeration technicians.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eValve Type\u003c\/strong\u003e: Schrader service valve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass body with aluminum shroud\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Silver\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: Single cap\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit of Measure\u003c\/strong\u003e: Each\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: RECTORSEAL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: ns-uni\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51383483597106,"sku":"NS-UNI","price":16.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312674337.webp?v=1782598059","url":"https:\/\/voomisupply.com\/products\/rectorseal-ns-uni-universal-locking-refrigerant-cap","provider":"Voomi Supply","version":"1.0","type":"link"}
