This fixed-orifice metering device controls refrigerant flow between the high-pressure and low-pressure sides of the refrigerant circuit. At 0.061 inches in orifice diameter, it meters refrigerant entering the evaporator coil, directly affecting system efficiency and cooling capacity. HVAC technicians install this component as part of routine service or system repair when the existing orifice is damaged, worn, or when recharging with a different refrigerant requires a metering device change.\u003c\/p\u003e\u003cp\u003eThis restrictor orifice is suited for residential and light-commercial air conditioning applications. It installs in the liquid line at the evaporator inlet, typically in a piston-style or fixed-orifice metering assembly. When a system calls for a fixed metering device rather than a TXV, this orifice provides the pressure drop needed for proper evaporator performance. Techs should verify the orifice size matches the system's design specifications before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eFixed orifice diameter of 0.061 inches for precise refrigerant metering\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct-fit restrictor for air conditioning refrigerant circuits\u003c\/li\u003e\n\u003cli\u003eSimple piston-style design with no moving parts to wear or fail\u003c\/li\u003e\n\u003cli\u003eCompatible with standard liquid-line orifice housings used in residential AC systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement restrictor orifice for air conditioning systems requiring a 0.061-inch fixed metering device.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a certified HVAC technician holding an EPA Section 608 refrigerant handling certification. Recover all system refrigerant before opening the refrigerant circuit. Confirm orifice orientation and flow direction before seating the piston in its housing. After reassembly, leak-test the connections and verify system pressures match manufacturer specifications before returning the unit to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Type\u003c\/strong\u003e: Restrictor Orifice\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrifice Diameter\u003c\/strong\u003e: 0.061 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Conditioner\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: WESTINGHOUSE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 664061R\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WESTINGHOUSE","offers":[{"title":"Default Title","offer_id":51284014596402,"sku":"664061R","price":15.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309277974.png?v=1781066081","url":"https:\/\/voomisupply.com\/products\/westinghouse-664061r-ac-restrictor-orifice-0-061-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
