Ten brass couplings with 1/4 in female NPT threads, Class 150 rating, straight configuration

  • Solid brass build resists corrosion for long service life

  • 1/4 inch female NPT threads connect to matching male fittings
  • California Proposition 65 warning notes chemical exposure risk

Brass Coupling 10 Pack for Plumbing Systems

This pack supplies ten straight brass couplings with 1/4 inch female NPT threads on both ends. They join two male-threaded pipes or fittings in water, air or inert-gas lines. The Class 150 rating suits standard low-pressure residential and light-commercial installations.

Solid Brass Construction with Threaded Ends

Each coupling is machined from brass for corrosion resistance and thread integrity. The 1/4 inch female NPT threads accept matching male NPT connections without adapters. A wrench flat allows secure tightening while the straight body keeps the joint compact in tight cavities.

Class 150 Pressure Rating Determines Suitability

The Class 150 designation defines the maximum working pressure for which these fittings are intended. Systems operating above that limit require a higher-class fitting. California Proposition 65 warnings apply because the brass contains listed chemicals.

Questions about this item

What does the Class 150 rating limit for this 1/4 in Female NPT coupling?

The Class 150 rating sets the maximum working pressure for the brass coupling under standard conditions.

What pipe thread size and type are required to join these couplings?

Each end uses a 1/4 in Female NPT thread, so matching 1/4 in Male NPT fittings are needed.

How do you seal the threads when installing these brass couplings, and what step is often missed?

Apply PTFE tape or pipe dope on the male threads, then tighten; the step often missed is wrapping tape in the thread direction so it does not unravel when tightened.
