Description
The International Comfort Products 1003687 is an OEM replacement pressure switch tube designed to restore proper pressure sensing function in compatible ICP heating systems. Measuring 1/8″ in diameter and 24″ in length, this tube connects the draft inducer or combustion air blower to the pressure switch, enabling accurate monitoring of airflow and combustion integrity.
Product Overview
Pressure switch tubes are a critical component in modern gas furnaces. They transmit negative pressure (vacuum) signals from the inducer assembly to the pressure switch, which verifies that proper draft is established before allowing ignition. A cracked, kinked, or deteriorated tube can cause nuisance lockouts or unsafe operation — making timely replacement essential.

Why Replace Your Pressure Switch Tube?
Over time, pressure switch tubes can crack, harden, or become blocked with condensate, leading to false pressure switch trips and furnace lockouts. Using a genuine ICP replacement tube ensures the correct diameter and length for a proper seal and accurate pressure transmission, keeping your system running safely and efficiently.
