Brass Elbow Pipe Fitting – 1" Internal & External Thread, Plumbing Connector

Match the fitting size to your pipe's nominal thread diameter. 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).

These fittings are generally compatible with NPT (National Pipe Taper) thread standards commonly used in US plumbing systems. Please confirm the thread standard for your specific application before ordering, or contact us to verify compatibility with BSP or other international thread standards.

Brass is naturally corrosion-resistant and performs well in damp or outdoor environments in most cases. It is generally suitable for garden irrigation, outdoor water lines, and exposed plumbing. For highly corrosive environments — such as saltwater or acidic conditions — additional sealing or alternative materials may be advisable.

Brass pipe fittings of this type typically handle working pressures up to 200 PSI for water applications, though the exact rating depends on the size and installation conditions. Ratings can vary between size variants. Contact us to confirm the pressure rating for your specific size before use in high-pressure systems.

Yes, applying PTFE (Teflon) tape or pipe thread sealant compound to the male threads before assembly is generally recommended. 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.

In 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.

Brass fittings are commonly used in natural gas and propane applications in many regions. However, suitability depends on local building codes, the specific gas type, and operating pressure. Always verify compliance with local plumbing and gas codes, and consult a licensed professional before using any fitting in a gas line application.
