Each cap features a corrosion-resistant aluminum shield and an integral neoprene O-ring that creates a positive seal against refrigerant loss. The locking design prevents unauthorized removal without the correct key tool, making these caps a standard compliance measure for refrigerant containment. Licensed HVAC technicians install these on central air conditioning systems, mini-splits, and other equipment using common HFC and A2L refrigerants.\u003c\/p\u003e\n\u003cp\u003eThese caps are suited for residential and light commercial HVAC installations wherever 1\/4-inch Schrader service ports are present. The universal fit covers the most common access valve configurations found on condensing units, line sets, and indoor air handlers. Buying in bulk quantities of 50 reduces per-unit cost for service fleets and shop stock. The color-coded, embossed body makes refrigerant identification and cap identification straightforward during service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eLocking design prevents unauthorized refrigerant access without the proper key tool\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant aluminum shield protects against environmental wear\u003c\/li\u003e\n  \u003cli\u003eIntegral neoprene O-ring provides a reliable seal against refrigerant leakage\u003c\/li\u003e\n  \u003cli\u003eCompatible with HFC and A2L refrigerants\u003c\/li\u003e\n  \u003cli\u003eColor-coded and embossed body supports quick identification at the service port\u003c\/li\u003e\n  \u003cli\u003eBulk 50-pack format suited for fleet technicians and shop inventory\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a universal replacement and new-installation cap for standard 1\/4-inch Schrader refrigerant access valves on residential and light commercial central air conditioning and mini-split systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and removal require the correct Novent key tool. HVAC technicians should recover or isolate refrigerant and relieve system pressure at the service port before swapping caps to avoid accidental release. Follow applicable EPA Section 608 refrigerant handling regulations and any local code requirements for refrigerant containment. Do not overtighten or force the cap without the proper key, as this can damage the valve core or cap locking mechanism.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 50 per pack\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShield Material\u003c\/strong\u003e: Aluminum (corrosion-resistant)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Neoprene O-ring\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRefrigerant Compatibility\u003c\/strong\u003e: HFCs and A2Ls\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Schrader refrigerant access valves\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-50\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51343173550386,"sku":"NS-50","price":410.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555016.jpg?v=1782019026","url":"https:\/\/voomisupply.com\/products\/rectorseal-ns-50-locking-refrigerant-cap-1-4-in-50-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
