Galvanised malleable iron reducing coupling with tapered female NPT threads

Value Brand

Value Brand Reducing Coupling 2 1/2 in x 1 1/2 in NPT

SKU CH-FY0D-0D8WM

Malleable iron reducing coupling connects 2 1/2 in NPT to 1 1/2 in NPT, galvanized Class 150 for plumbing systems

  • Reduces pipe size from 2 1/2 in to 1 1/2 in NPT
  • Malleable iron construction provides durable galvanized fitting
  • Class 150 pressure rating suits standard plumbing systems
  • Female NPT threads on both ends ensure secure connections
  • New condition guarantees unused, factory-fresh component

Reducing Coupling 2 1/2 in x 1 1/2 in NPT

This galvanised malleable iron fitting joins two female NPT threads of different sizes. It is rated for Class 150 service and suits plumbing systems that require a straight reduction. The component is supplied new and ready for installation.

Build Quality and Daily Use

Malleable iron construction provides mechanical strength for threaded pipe connections. The galvanised coating protects against corrosion in typical water or air lines. Both ends use standard NPT threads so the coupling threads directly onto matched pipe nipples or fittings without adapters.

Upgrade Context

This coupling replaces a worn or damaged reducer in an existing NPT pipeline. It is also the correct choice when a system redesign calls for a step down from 2 1/2 in to 1 1/2 in pipe. The jump is worth it when the current joint leaks or when the line size must change at a single point.

Questions about this item

What pressure does the Class 150 rating cap this reducing coupling at?

The Class 150 rating limits the working pressure to 150 psi for this galvanized malleable iron fitting.

What pipe threads are needed to fit the 2 1/2 in and 1 1/2 in NPT ends?

Both ends use Female NPT threads, so you need matching Male NPT pipe threads on the 2 1/2 in and 1 1/2 in pipes.

How do you seal the NPT threads and which step is often missed?

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