These caps are precision-machined from high-grade brass and fitted with a protective aluminum shroud and an integral neoprene O-ring. They are designed to resist crushing and unauthorized removal without the correct key tool. The torque-limiter design prevents overtightening during installation. HVAC technicians install these caps on service valves to prevent accidental refrigerant loss, reduce the risk of refrigerant mixing, and support refrigerant containment best practices required under EPA Section 608 regulations.\u003c\/p\u003e\u003cp\u003eThese caps are intended for use on R-410A HVAC equipment service valves that use 5\/16-inch Euro-thread ports. Typical applications include residential and light-commercial split systems and heat pumps where R-410A is the system refrigerant. The color-coded design allows quick visual identification of the refrigerant type at the service valve, which is useful during routine maintenance, seasonal startup, and refrigerant recovery operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSized for 5\/16-inch Euro threads common on R-410A service valves\u003c\/li\u003e\n\u003cli\u003ePrecision-machined brass body resists crushing and corrosion\u003c\/li\u003e\n\u003cli\u003eAluminum shroud adds physical protection against tampering\u003c\/li\u003e\n\u003cli\u003eIntegral neoprene O-ring helps maintain a positive seal at the port\u003c\/li\u003e\n\u003cli\u003eTorque-limiter design prevents overtightening during cap installation\u003c\/li\u003e\n\u003cli\u003eColor-coded for quick visual refrigerant-type identification\u003c\/li\u003e\n\u003cli\u003eRequires a special key tool for installation and removal, deterring unauthorized access\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for R-410A HVAC equipment service valves with 5\/16-inch Euro-thread refrigerant ports.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and removal require the manufacturer-specified key tool — standard hand tools will not engage the tamper-resistant design. HVAC technicians should recover or isolate system refrigerant as required before servicing any valve or cap. Follow EPA Section 608 refrigerant handling requirements and applicable local codes during all service valve work. Inspect the O-ring for damage before reinstalling caps after any service visit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5\/16 inch Euro\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Refrigerant\u003c\/strong\u003e: R-410A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShroud Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Material\u003c\/strong\u003e: Neoprene O-ring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity\u003c\/strong\u003e: 2 caps per pack\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: NPE-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RECTORSEAL","offers":[{"title":"Default Title","offer_id":51347099582770,"sku":"NPE-2","price":56.22,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555071.png?v=1782097661","url":"https:\/\/voomisupply.com\/products\/rectorseal-npe-2-locking-refrigerant-cap-5-16-in-r-410a-2-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
