Red Brass Pipe Nipple 1 in MNPT x 11 in

This seamless red brass nipple fits 1-inch nominal pipe systems and carries a Schedule 40 wall. It is rated for 190 psi at 450 degrees F and 755 psi steam at 300 degrees F. The fitting suits air, natural gas, oil, potable water and steam service.

Upgrade From Threaded Steel or Lower-Grade Brass

Replaces carbon-steel nipples where corrosion resistance matters and upgrades from alloys not meeting ASTM B43. The jump is worth it when the system sees 400-degree F peaks or -20-degree F lows and demands Class 150 compatibility.

Limits of Threaded Schedule 40 Connections

The 1 21/64-inch outside diameter and 11-inch length fix the installed envelope; no expansion or flex is built in. Threaded joints at this pressure class require proper sealant and torque, and the California Proposition 65 notice flags chemical content for regulated environments.

Questions about this item

What thread size does the 1 in MNPT end need to match?

The nipple has a 1 in male NPT thread that mates with a 1 in female NPT fitting, so the mating port must be 1 in NPT female.

How do I seal the threads during installation without causing leaks?

Apply PTFE tape or pipe-thread sealant on the male threads only, tighten to the recommended turns past hand-tight, and avoid over-tightening which can crack the brass.

When should I plan to replace this nipple in a steam system?

In steam service the rating is 755 psi at 300 °F; inspect for erosion or thread deformation at each scheduled shutdown and replace if wall loss or leakage appears.
