Galvanized reducing coupling joins 4" and 2-1/2" FNPT threads for HVAC systems

  • Galvanised steel resists corrosion in HVAC systems
  • Reducing coupling joins 4 inch to 2-1/2 inch FNPT threads
  • Legend Valve model 352-565 ensures reliable pipe connections
  • New condition guarantees full factory performance and compliance
  • California Proposition 65 warning discloses regulated chemical content

4" x 2-1/2" Galvanized Reducing Coupling

The Legend Valve 352-565 connects a four-inch female NPT pipe to a two-and-a-half-inch female NPT pipe in HVAC systems. Galvanized steel construction resists corrosion in damp mechanical rooms. The reducing design joins dissimilar pipe sizes without extra fittings. California Proposition 65 warnings apply for cancer and reproductive harm.

Replaces mismatched pipe connections

This coupling replaces improvised reducer assemblies that use multiple nipples and bushings. The single-piece body cuts potential leak paths and reduces installation labour. The jump is worth it when joining main trunk lines to branch runs in hydronic or steam distribution. It eliminates the need to thread and seal separate reduction components.

Handles standard HVAC pressure and temperature

The galvanized finish withstands typical hot-water and low-pressure steam conditions found in commercial heating loops. It runs out when system chemistry demands stainless steel or brass for aggressive water treatment. The FNPT threads seal with standard pipe compound or tape. Not suited for potable water lines or high-purity process piping.

Questions about this item

What pipe diameters does the 352-565 reducing coupling connect?

The coupling joins a 4 inch female NPT pipe to a 2-1/2 inch female NPT pipe.

How is the galvanized reducing coupling installed onto the pipe threads?

Apply thread sealant to the male threads, then tighten each end onto the corresponding female NPT pipe using a pipe wrench; the common mistake is skipping sealant and causing leaks.

When should the galvanized reducing coupling be inspected or replaced?

Inspect for white zinc corrosion or thread damage during routine HVAC maintenance; replace if the galvanized coating is worn through or if joints show seepage.
