For example, a 1\" fitting connects to 1\" NPT pipe. If you're reducing between two pipe sizes, select the variant that lists both diameters (e.g., 1\"–3\/4\"). When in doubt, measure the outer diameter of your pipe threads and compare to standard NPT sizing charts. A 1\" NPT pipe has an outer thread diameter of approximately 1.315\" (33.4mm).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat thread standard do these brass elbow fittings use?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eThese fittings are generally compatible with NPT (National Pipe Taper) thread standards commonly used in US plumbing systems.

This ensures a leak-free connection, protects the threads from galling, and makes future disassembly easier. Wrap the tape clockwise (when viewed from the thread end) for 2–3 layers.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat tools do I need to install a brass elbow pipe fitting?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eIn most cases, a pipe wrench or adjustable wrench is sufficient. Hand-tighten the fitting first until snug, then use a wrench for approximately 1–2 additional turns. Avoid over-tightening — brass can crack under excessive torque. Use a second wrench to hold the pipe steady while tightening the fitting.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eAre these fittings suitable for gas lines?\u003c\/summary\u003e\n\u003cdiv class=\"hdiy-faq-body\"\u003e\n\u003cp\u003eBrass fittings are commonly used in natural gas and propane applications in many regions.
