About Pipe and Fittings

Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Low-Pressure Brass and Bronze Threaded Pipe Fittings

Use these fittings in low-pressure flow applications. They have good corrosion resistance. Fittings rated for use with drinking water meet NSF/ANSI 61 safety standards.

Right-angle tees are also known as run tees. Inline tees are also known as branch tees. Dual tees reduce on all three ends.

Low-Pressure Plated Brass Threaded Pipe Fittings

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

Chrome-plated brass fittings are shinier and withstand corrosion better than nickel-plated brass fittings.

Inline tees are also known as branch tees.
