SKU CH-65SB-DFSGA

Reducer connects 2-inch and 1-1/2-inch FNPT threads, forged steel Class 3000 rated for 500 psi at 150 degrees F

  • Handles 500 psi at 150 °F for reliable high-pressure service
  • Class 3000 forged steel construction resists deformation under heavy loads
  • Schedule 160 compatibility fits thick-wall piping systems
  • Female NPT threads on both ends allow direct threaded connections
  • Black finish protects steel surfaces from corrosion

Anvil 2" x 1-1/2" FNPT Reducer

This Anvil reducer connects a two-inch female threaded pipe to a one-and-a-half-inch female threaded pipe. It is forged from black steel for plumbing installations that require a straight, durable transition between different pipe diameters. The fitting suits residential and commercial bathware systems.

Class 3000 pressure rating and 500 psi limit

The forged steel body meets Class 3000 specifications and handles up to 500 psi at 150 degrees Fahrenheit. Designed for Schedule 160 pipe, it maintains structural integrity under high-pressure hot water or steam lines without vibration or leakage in normal service.

Female threaded ends on both ports

Both the two-inch and one-and-a-half-inch ports use FNPT threads, so the reducer joins two male-threaded pipes directly without extra adapters. Black forged steel resists corrosion in wet environments, and the straight profile fits tight mechanical rooms where space for sweat or flanged connections is limited.

Questions about this item

How do I install the Anvil 0361178502 reducer without damaging the forged steel threads?

Apply PTFE tape or pipe thread sealant to the male threads only, then hand-tighten the reducer into the 2-inch female port before final tightening with a wrench on the hex flats; over-torquing the 1-1/2-inch female side first is the common error that strips the Class 3000 forged steel threads.

What maintenance or replacement will this Schedule 160 reducer need over time?

Inspect the FNPT joints annually for seepage; re-apply thread sealant if minor weeping appears, but replace the fitting immediately if corrosion or cracking is found on the black forged steel body, as Schedule 160 wall thickness does not prevent internal erosion from aggressive water chemistry.

At what pressure limit does this Class 3000 reducer become the weak point in a hot-water loop?

The 500 psi rating at 150 degrees F is the first limit reached under sustained use; operating above that temperature or pressure combination risks permanent deformation of the forged steel reducer before other Schedule 160 components yield.
