Manufactured from brass, this fitting handles a maximum working pressure of 750 psi and operates across a wide temperature range of -65 degrees F to 250 degrees F. It uses a 1\/4-18 NPTF thread standard on the male threaded end, ensuring a pressure-tight mechanical seal without relying solely on thread sealant. Plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting in fluid and gas distribution lines where a reliable compression-to-threaded transition is required.\u003c\/p\u003e\u003cp\u003eThis connector is suited for residential and light commercial plumbing, HVAC refrigerant accessory lines, instrumentation tubing, and hydraulic or pneumatic systems operating within its rated pressure and temperature limits. The compression end eliminates the need for soldering or brazing at the tube connection, making it practical in retrofit and service scenarios where open flame is not desirable or permitted. Its brass construction resists corrosion in water, air, and many common fluid media encountered in trade service work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction for corrosion resistance in water, air, and common fluid service\u003c\/li\u003e\n\u003cli\u003eMaximum working pressure of 750 psi for demanding plumbing and pneumatic applications\u003c\/li\u003e\n\u003cli\u003eWide service temperature range: -65 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003e1\/4-18 NPTF thread standard ensures a pressure-tight male threaded connection\u003c\/li\u003e\n\u003cli\u003eCompression x MNPT end configuration eliminates the need for soldering at the tube end\u003c\/li\u003e\n\u003cli\u003eCompact single-piece fitting suitable for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or service fitting for compression tube-to-male NPT connections in residential and commercial plumbing, HVAC, pneumatic, and instrumentation systems rated within the specified pressure and temperature limits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified pipefitter in accordance with applicable local codes and ASME or NPTF standards. Shut off and depressurize the system fully before disconnecting or installing any fitting. Apply an appropriate thread sealant or PTFE tape to the MNPT threads per job requirements; the NPTF thread form is designed for dry-seal performance but sealant is commonly used in practice. Tighten the compression nut to snug plus the recommended turns per the tube material and size without over-torquing, and pressure-test the assembly before returning the system to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x MNPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 750 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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 68CA-8-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51544658870578,"sku":"68CA-8-4","price":20.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/505933a18084420482f7b9bc03e621bc.jpg?v=1785932802","url":"https:\/\/voomisupply.com\/products\/parker-68ca-8-4-compression-x-mnpt-brass-connector","provider":"Voomi Supply","version":"1.0","type":"link"}
