The Caleffi 502710A is a Robocal float-style automatic air vent with a 1/8" male threaded connection and a built-in check valve. It releases air that collects at high points of a closed hydronic system.

The check valve lets the vent be removed for service without draining the system. Maximum working pressure is 150 psi, maximum venting pressure is 90 psi and maximum temperature is 240°F.

Before ordering: confirm that the port is a 1/8" female thread to receive this male vent. For water (hydronic) systems only, within the pressure and temperature limits above.
