## Summary description

Manual air vent FERRO O18Y designed for removing trapped air from heating and plumbing systems. Features 1/2" threaded connection, integrated O-ring seal and key-operated cap for controlled venting. Suitable for radiators, manifolds and pipeline sections where manual bleed with a vent key is required to improve system efficiency and prevent air locks.

## Long description

Manual air vent FERRO O18Y 1/2" with O-ring, key-operated is a compact valve designed for removing trapped air from heating and plumbing systems. It features a 1/2" threaded connection and an integrated O-ring seal to ensure a tight fit and minimise leaks. The key-operated cap allows controlled venting and prevents accidental opening, making it suitable for use on radiators, manifold panels and short pipeline sections that require periodic manual bleeding to maintain efficient circulation and reduce air locks.
Advantages
The valve offers a simple mechanical design that requires no power supply and provides reliable venting through a key-operated mechanism. The integrated O-ring improves sealing at the connection point and reduces the risk of drips. Its 1/2" thread is compatible with common heating and plumbing fittings, and the compact body facilitates installation in confined spaces. The key cap enables safer and metered release of air, helping to avoid sudden spurts of water.
Suitable for
 Bleeding radiators and convectors
 Venting manifold and distribution headers
 Removing air from short sections of pipework
 Use in residential and light commercial heating systems
Key specifications
 Connection size: 1/2" threaded
 Operation: manual, key-operated cap
 Seal type: integrated O-ring
 Material: corrosion-resistant valve body (manufacturer standard)
 Application temperature: suitable for typical heating system temperatures (manufacturer standard)
How to use
Shut down the circulation pump or isolate the section of the system if necessary to reduce flow. Fit the 1/2" threaded vent into a compatible port and tighten to a secure, leak-free connection without over-torquing to protect the O-ring. To bleed, place a container under the vent, insert the vent key into the cap and turn slowly to open until air is released; tighten the cap once only water flows steadily. Follow system-specific procedures for pressure and temperature safety when bleeding.
Usage recommendations
Regularly check the vent for leaks and proper operation during seasonal maintenance. Replace the O-ring or the entire valve if persistent leaking or corrosion is observed. Use the dedicated key to operate the cap and avoid forcing the mechanism to extend component life.
