The sleeve seats between the fitting body and compression nut, deforming onto the tubing wall to form a reliable mechanical seal without threading or soldering. Built from brass for corrosion resistance and durability, it supports a maximum working pressure of 2800 psi and handles temperatures ranging from -65 degrees F to 250 degrees F. Licensed plumbers, HVAC technicians, and pipefitters install this component as part of standard compression assembly work on 3\/16 inch OD tubing.\u003c\/p\u003e\n\u003cp\u003eThe 61CA-3 sleeve suits residential and light commercial applications wherever 3\/16 inch OD tubing is joined using Parker compression-style fittings. Typical install scenarios include refrigerant line connections, instrument tubing, hydraulic pilot lines, and fuel or oil service lines. The NPTF thread standard alignment ensures compatibility within Parker compression fitting assemblies. It is sold individually but carries a minimum order quantity of 5 units, making it practical for stocking or multi-point service calls.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBrass construction resists corrosion in fluid and gas service environments\u003c\/li\u003e\n  \u003cli\u003eRated to 2800 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eFits 3\/16 inch outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003eNPTF thread standard for consistent fitment within compression assemblies\u003c\/li\u003e\n  \u003cli\u003eNo soldering or threading required — mechanical compression seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Parker compression fitting assemblies requiring a sleeve for 3\/16 inch OD tubing. Consult Parker fitting series documentation to confirm body and nut compatibility before assembly.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers, HVAC technicians, or pipefitters following applicable IPC and IFGC guidelines for the service type. Shut off and depressurize the line completely before disassembling any compression fitting. Seat the sleeve squarely on the tubing before threading the compression nut to avoid cocking or incomplete bite. Do not over-tighten the compression nut, as this can split the sleeve or damage the tubing wall.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Sleeve\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2800 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -65 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 61CA-3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543653122354,"sku":"61CA-3","price":16.48,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e91d4bc5d769e9c9cdb6e374276560c7.jpg?v=1785921269","url":"https:\/\/voomisupply.com\/products\/parker-61ca-3-compression-tube-sleeve-brass-3-16-in","provider":"Voomi Supply","version":"1.0","type":"link"}
