Red Brass Nipple for Pressurised Systems

This 12-inch red brass pipe nipple is built for air, natural gas, oil, potable water and steam lines. It carries a maximum operating pressure of 282 psi at 450 degrees Fahrenheit and meets ASTM B43 material grade. The seamless construction supports Class 300 fitting compatibility across a temperature range from minus 20 to 400 degrees Fahrenheit.

Upgrade from Standard Brass or Threaded Steel

The red brass alloy resists dezincification and corrosion better than yellow brass in aggressive water or steam service. Switching is worth it when the system demands the higher 282 psi steam rating or the broader thermal envelope up to 450 degrees Fahrenheit. It replaces lower-rated nipples that cannot hold pressure at elevated temperatures.

Limited to 1/4-Inch Nominal Bore and Male Threads

The quarter-inch nominal size fixes the inside diameter, restricting flow volume for high-demand circuits. Both ends are male NPT, so the nipple cannot connect directly to another male fitting without a female coupler. California Proposition 65 warnings apply due to listed chemicals.

Questions about this item

What thread size and length does the 1/4" MNPT nipple need for a watertight seal?

The nipple has 1/4 inch male NPT threads on each end and an overall length of 12 inches, requiring matching female NPT fittings for a proper seal.

How do I install the Schedule 80 red brass nipple without damaging the threads?

Apply PTFE tape or pipe thread sealant to the male threads, hand-tighten into the female fitting, then finish with a wrench for one to two turns; over-tightening can crack the fitting or strip the threads.

When should I replace the red brass nipple in a potable water or steam system?

Inspect annually for greenish dezincification, white mineral deposits, or leaks at the threads; replace immediately if the wall shows pitting, the threads are deformed, or the system exceeds 282 psi at 450 °F.
