Brass Steam Vent
The BELL & GOSSETT 499170 is a brass air vent designed for steam systems operating up to 10 psi and 240F. It installs horizontally through a single 1/8 in male NPT side inlet. This new component suits maintenance teams and facility engineers who need reliable air removal from steam piping or equipment.
Pressure and Temperature Limits
The vent handles a maximum allowable pressure of 10 psi and a maximum media temperature of 240F. These ratings define the practical envelope for safe operation on low-pressure steam lines. Exceeding either limit risks valve failure or unsafe discharge, so the device must be matched to system conditions that stay within both boundaries.
Capacity and Service Scope
The single 1/8 in port vents air from the connected volume at low-pressure steam conditions. It provides adequate capacity for small steam mains, radiators, or process vessels where the connection size matches the port. Larger steam headers or high-capacity mains requiring greater airflow will need additional or larger vents to achieve effective air removal.

Questions about this item
Should I pick the 10 psi or a higher-pressure air vent for my steam system?
Choose the 10 psi model when your steam system operates at or below that pressure; a higher-rated vent is only needed if the system exceeds 10 psi.
What does the 240F rating mean once the vent is installed in my boiler?
The 240F rating shows the maximum steam temperature the brass body can withstand continuously without degrading.
How does the 1/8 in male NPT inlet limit where I can mount this vent?
The 1/8 in male NPT side inlet requires a matching female NPT port on the pipe or fitting, and the vent must be installed horizontally.
