The fitting uses a compression-style end connection on both run ports and a male NPT (MNPT) branch port, allowing inline tube routing with a threaded branch takeoff. Rated to 300 psi maximum working pressure and built to SAE J-512 standards, this tee handles operating temperatures from -65 degrees F to 250 degrees F. It is suited for hydraulic, refrigeration, and instrumentation tubing work where a reliable, leak-resistant mechanical connection is required.\u003c\/p\u003e\u003cp\u003eThis fitting is installed in residential and light commercial systems where 1\/4-inch OD tubing intersects with a threaded port — common in refrigeration lines, compressed air distribution, fuel systems, and hydraulic instrument tubing. The male NPT branch allows direct threaded attachment to a valve, gauge, sensor, or manifold without additional adapters. HVAC technicians, plumbers, and fluid-systems mechanics working with small-bore tubing will encounter this fitting in service and new-construction applications alike.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBrass construction provides corrosion resistance and good machinability for reliable bite-ring sealing\u003c\/li\u003e\n\u003cli\u003eCompression x MNPT x Compression end connections allow inline tube run with a threaded branch takeoff\u003c\/li\u003e\n\u003cli\u003eRated to 300 psi maximum working pressure for use in moderate-pressure fluid and pneumatic systems\u003c\/li\u003e\n\u003cli\u003eWide temperature range of -65 degrees F to 250 degrees F suits refrigeration and heated-line applications\u003c\/li\u003e\n\u003cli\u003eMeets SAE J-512 standards for compression tube fittings\u003c\/li\u003e\n\u003cli\u003e1\/4-18 NPTF thread on the male branch port ensures pressure-tight threaded engagement\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style and aftermarket replacement compression tube male run tee for systems using 1\/4-inch OD tubing with a 1\/4-18 NPTF male branch connection, conforming to SAE J-512 dimensional standards.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with compression fittings and applicable codes such as the IPC or system-specific refrigeration standards. Shut off and depressurize the line completely before disassembly or fitting installation. Compression fittings require proper tube squareness and deburring at the cut end to achieve a leak-free bite-ring seat — do not overtighten, as this can deform the ferrule and compromise the seal. Apply thread sealant appropriate for the service fluid to the NPTF male threads before assembly.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Run Tee\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x MNPT x Compression\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inches\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: 300 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\u003eStandards\u003c\/strong\u003e: SAE J-512\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: 171C-4-4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51543102292274,"sku":"171C-4-4","price":22.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb9311f3048cc2554a4babc050040312.jpg?v=1785915501","url":"https:\/\/voomisupply.com\/products\/parker-171c-4-4-compression-male-run-tee-1-4-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
