Why we built NHG
You might find it for less locally. Independent retailers often offer competitive pricing — some products are even cheaper in-store than online.
Real expert advice — not search results. Independent hardware staff know their inventory and the local conditions you're working in.
Keep the neighborhood working. Every dollar spent at an independent retailer returns roughly 3x more to your local economy than at a national chain.

Why this red brass nipple stands out

Unlike generic fittings, this Anderson Metals nipple combines a lead-free formulation with ANSI certification, ensuring safer, standards-aligned performance in threaded piping systems. The red brass material offers superior strength and corrosion resistance, making it a trusted choice for varying climates and installation environments. The 6 in. length provides versatility for extending or bridging gaps between components, while the identical MPT ends ensure compatibility with a wide range of 3/8 in. threaded fittings and valves.

Ideal use scenarios

  • Extending a small-diameter water line where space is limited and alignment matters.
  • Connecting valves, sensors, or fixtures that require a precise 3/8 in. MPT threaded transition.
  • Retrofits and minor piping upgrades in residential or light commercial projects where lead-free materials are preferred.

Practical installation tips

To ensure a secure, leak-free connection, apply thread sealant tape or pipe dope compatible with brass fittings. Hand-tighten, then give a quarter-turn with a wrench to establish a proper seal without over-torquing, which could distort threads. Check for leaks after pressurizing the system and re-tighten if necessary. Always verify that the operating pressure and temperature remain within the nipple’s rated limits (up to 890 psi and up to 200Β°F).

Who benefits most

This 6 in. red brass pipe nipple is an excellent match for professionals and DIY enthusiasts working on plumbing, heating, and potable-water-related projects who demand safety, durability, and certification-backed performance from a straightforward MPT-to-MPT connector.

Choose the Anderson Metals 3/8 in. MPT x 3/8 in. MPT Red Brass Pipe Nipple, 6 in. L for a reliable, standards-aligned solution that simplifies threaded piping installations while delivering long-lasting service.
