It accepts tubing with a 3\/16 inch outside diameter on the compression end and terminates in a 1\/8 inch male NPT thread on the pipe end. This fitting is commonly used in fluid and pneumatic line assemblies where a direction change is needed at a threaded port. Plumbers, HVAC technicians, and industrial pipe fitters install this type of fitting in low-pressure tubing runs where a reliable, leak-resistant mechanical connection is required without soldering or brazing.\u003c\/p\u003e\n\u003cp\u003eThe 691X3 is suited for light commercial and residential applications involving tubing routed to threaded instrument ports, valve bodies, or control devices. Typical installations include refrigeration tubing tie-ins, pneumatic control lines, and small-bore fluid transfer systems where a 90-degree directional change at a threaded connection point is necessary. The compression end secures the tubing mechanically, making it accessible for service without specialized tools.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e90-degree male elbow configuration allows directional routing at threaded port connections\u003c\/li\u003e\n  \u003cli\u003eCompression end fits 3\/16 inch outside diameter tubing for a secure, tool-assisted mechanical grip\u003c\/li\u003e\n  \u003cli\u003e1\/8 inch MNPT thread end connects directly to standard female NPT ports\u003c\/li\u003e\n  \u003cli\u003eCompression x MNPT end configuration eliminates the need for soldering or brazing at the joint\u003c\/li\u003e\n  \u003cli\u003eCompact form factor suited for tight installation spaces in control panels and equipment enclosures\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install compression fitting for tubing systems using 3\/16 inch outside diameter tubing terminating at 1\/8 inch female NPT threaded ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis fitting is typically installed by licensed plumbers, HVAC technicians, or instrumentation technicians. Depressurize and isolate the tubing circuit fully before disassembling or installing compression fittings. Hand-tighten the compression nut onto the tubing, then snug with a wrench — avoid overtightening, which can deform the ferrule and compromise the seal. Apply appropriate thread sealant or PTFE tape to the MNPT threads in accordance with the applicable installation code for the fluid or gas being handled.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Male Elbow\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Connections\u003c\/strong\u003e: Compression x MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inches MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.047 pounds\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: EATON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 691X3\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EATON","offers":[{"title":"Default Title","offer_id":51539489784114,"sku":"691X3","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c15ec98e24b25e4789a41d194857a899.jpg?v=1785841531","url":"https:\/\/voomisupply.com\/products\/eaton-691x3-compression-tube-male-elbow-3-16-od-x-1-8-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
