Eccentric Reducer Coupling 2-1/2 x 1-1/4

This Anvil eccentric reducer coupling connects a 2-1/2 inch pipe to a 1-1/4 inch pipe. It is made of cast iron and rated Class 125 for Schedule 40 piping. Both ends feature female threaded connections for straightforward installation in plumbing systems.

Sustained pressure performance

The coupling handles a maximum operating pressure of 175 psi at temperatures up to 150 degrees Fahrenheit. Cast iron construction provides consistent structural integrity under continuous pressurised flow. The straight eccentric design maintains alignment while reducing turbulence during extended use.

Class 125 pressure rating

The Class 125 rating determines the pressure and temperature limits for this fitting. It is suitable for systems operating within 175 psi at 150 degrees Fahrenheit. Installers must verify that the system design stays within these parameters for safe operation.

Questions about this item

How much heat can the cast-iron body handle before the 175 psi rating drops?

The coupling is rated for 175 psi at up to 150 degrees F, so continuous operation at that temperature stays within the published limit.

What pipe threads must I already have to install this 2-1/2 by 1-1/4 reducer?

Both ends are female NPT, so you need a 2-1/2 inch male-threaded pipe on one side and a 1-1/4 inch male-threaded pipe on the other.

Will this Class 125 Schedule 40 fitting mate with older black-iron pipe I already have in the basement?

Yes, it follows the same Class 125 Schedule 40 dimensions, so it threads onto existing black-iron pipe of matching sizes without adapters.
