It transitions between a compression-style tube end and a 1\/8-inch MNPT threaded connection at a 45-degree angle, allowing directional routing of tubing in tight or angled installations. With a maximum working pressure rating of 2100 psi, this fitting is built for high-pressure fluid and gas line applications. It is installed by licensed plumbers, HVAC technicians, and instrumentation fitters working on refrigeration, pneumatic, hydraulic, or process piping systems where a reliable, leak-free compression-to-NPT transition is required.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and commercial applications where tubing must change direction at a 45-degree angle before connecting to a male NPT port. Common install scenarios include instrument lines, control tubing, refrigeration service ports, and pneumatic supply lines. The compression end accepts standard tubing and cinches the ferrule mechanically without soldering or brazing, making it a practical choice in service and retrofit work where open-flame procedures are restricted or impractical.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e45-degree elbow geometry routes tubing at an angle to reduce stress on lines and fittings\u003c\/li\u003e\n\u003cli\u003eCompression x MNPT end connections eliminate the need for soldering or brazing\u003c\/li\u003e\n\u003cli\u003eBrass construction provides corrosion resistance and compatibility with a wide range of fluids and gases\u003c\/li\u003e\n\u003cli\u003e2100 psi maximum working pressure supports high-pressure service applications\u003c\/li\u003e\n\u003cli\u003e1\/8-inch MPT thread size fits standard NPT-threaded ports common in HVAC and plumbing systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style compression-to-MNPT fitting for use in refrigeration, pneumatic, hydraulic, and process piping systems requiring a 45-degree elbow transition at a 1\/8-inch male NPT port.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or qualified instrumentation fitter. Shut off and depressurize the system completely before removing or installing any fittings. Hand-tighten the compression nut first, then advance with a wrench per standard compression fitting practice — do not overtighten, as over-compression can distort the ferrule and cause leaks. Apply thread sealant tape or paste to the MNPT threads in accordance with applicable plumbing or mechanical codes.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male 45 Degree Elbow\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: MPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 2100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.11 pounds\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: 179HD-4-2\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541597290802,"sku":"179HD-4-2","price":48.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5f11ad00a66b221a9c3f07a70cebd738.jpg?v=1785880292","url":"https:\/\/voomisupply.com\/products\/parker-179hd-4-2-brass-45-degree-elbow-1-8-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
