Nordyne 632447R 0.85″wc 1/4 Barbed STSP Pressure Switch

Description

The Nordyne 632447R is a factory-replacement single-trip single-pole (STSP) pressure switch engineered to protect your furnace from unsafe operating conditions. Rated at a precise 0.85″ water column (wc) set point, this switch monitors negative pressure in the flue or inducer circuit and interrupts the control circuit if adequate draft is not established — helping prevent unsafe combustion and potential heat exchanger damage.

Featuring a 1/4″ barbed port connection, the 632447R provides a secure, leak-free hose attachment to the inducer assembly or collector box tubing. As a genuine Nordyne OEM replacement part, it is engineered to exact factory specifications for reliable drop-in compatibility with applicable Nordyne-family equipment.
