Value Brand 3" x 2" Malleable Iron Reducer Coupling

3" x 2" Malleable Iron Reducer Coupling

This Value Brand reducer coupling connects a 3 inch pipe to a 2 inch pipe using FNPT threads. It is made from malleable iron rated to Class 150 and carries FM Approved and UL Listed markings. The fitting meets ASME B 16.3 and B 16.4 plus ASTM A-197 and ASTM A47 standards. It suits installers needing a durable transition between dissimilar pipe diameters.

Pressure and temperature limits

The coupling handles a maximum pressure of 300 psi at 150 Degrees F and a saturated steam pressure of 150 psi. Its operating temperature range spans from -20 Degrees to 366 Degrees F. These ratings define the safe envelope for water, oil, air or steam service. Exceeding either limit risks joint failure or reduced service life.

Compatibility checks before ordering

Verify that both pipe ends are threaded to FNPT and that the 3 inch and 2 inch nominal sizes match your existing piping. Confirm the system design pressure and temperature stay within the 300 psi and 366 Degrees F maxima. Ensure the Class 150 rating aligns with the rest of the piping specification. Check local codes for any additional approval requirements.
