Y602 Series vent assemblies help to prevent the obstruction of vent openings, allowing proper air or gas flow for regulator spring cases, remote vent lines, actuator diaphragm casings, and miscellaneous applications. These vent assemblies are available in either angle or straight styles. Typically, angle vent assemblies protect vent openings that face sideways, and straight vent assemblies protect vent openings that face either up or down.
