For example, a 3\/4\" fitting connects to 3\/4\" NPT-threaded pipe. If you're branching to a smaller line, select a reducing tee that matches your run and branch diameters. When in doubt, measure the outer diameter of your pipe and consult an NPT size chart — typically a 3\/4\" NPT pipe has an OD of approximately 1.050\" (26.7mm), and a 1\" NPT pipe has an OD of approximately 1.315\" (33.4mm).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat do FFF, FFM, MFM, and MMM mean in the size options?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese letter codes indicate the thread type on each of the three ports of the tee fitting. \u003cstrong\u003eF = Female\u003c\/strong\u003e (internal\/socket thread) and \u003cstrong\u003eM = Male\u003c\/strong\u003e (external thread).

NPT tapered threads rely on thread engagement plus a sealant to achieve a leak-free connection. Apply PTFE (Teflon) tape or a pipe thread sealant compound to all male threads before assembly.
