About Brass Fittings and Nipples

Brass fittings and nipples are essential components in plumbing, HVAC, hydraulic, and industrial applications due to their strength, resistance to corrosion, and versatility. Whether you’re running gas lines, air compressor systems, potable water connections, or custom mechanical setups, choosing the right brass pipe fittings is critical for long-term performance and safety.

At Plumbingsell, we carry a wide range of brass fittings, pipe nipples, and specialty connection types to help you adapt, seal, reduce, extend, or redirect piping efficiently. These fittings are compatible with brass, iron, copper, and many fluid-system materials, making them a reliable choice for both professionals and DIY installers.

Why Choose Brass Fittings?

Brass is preferred in plumbing systems because it offers:

• Excellent corrosion and leak resistance
• High-temperature tolerance for hot water and steam applications
• Strong mechanical durability—ideal for high-pressure systems
• Safe use with potable water (lead-free brass options available)
• Versatility in residential, commercial, industrial, and HVAC installs

Unlike plastic or mild steel fittings, brass pipe fittings maintain integrity for decades, even in harsh environments.

Male vs. Female Threading: What’s the Difference?

Most brass fittings include standardized threaded connection points:

• Male Thread (M): Threads on the outside of the fitting
• Female Thread (F): Threads on the inside, receiving a male threaded pipe

Some fittings include both male and female ends, making them ideal for transitions.
