Automatic Vent Air Valve, 1/4 Inch Male Connection

The Auto‑Vent is a reliable, float‑operated air elimination valve designed for hydronic, hot water, and steam heating systems. This automatic air vent removes trapped air from radiators, pipelines, and other system components, improving circulation efficiency and preventing air pockets that can reduce heating performance. Constructed from durable brass with a copper finish and polished brass cover, the Auto‑Vent is built for long‑lasting performance in demanding heating environments. Its internal design features a self‑closing float mechanism with a Monel metal spring and EPDM or neoprene seat, allowing it to automatically vent air while preventing water leakage once the system is pressurized. With a compact design and a 1/4 inch male pipe connection, the vent is easy to install in vertical mounting positions on radiators, boilers, and piping systems. It operates at pressures up to 75 PSI and temperatures up to approximately 240 Degrees F, making it suitable for a wide range of heating and cooling systems, including those using glycol solutions.
