Angle Automatic Air Vent PINTOSSI ART.519-12 chrome 1/2" for heating and plumbing

Automatic angle air vent PINTOSSI ART.519-12 in chrome finish with 1/2" threaded connection is a compact mechanical device designed to remove trapped air from closed heating and plumbing systems. Installed at an angled position on radiators, manifolds or pipeline branches, the vent automatically releases accumulated air pockets to help maintain continuous circulation, reduce noise and minimise the risk of corrosion and uneven heat distribution.

Advantages

The chrome-plated body provides corrosion resistance and a polished surface that matches most visible heating fittings. The 1/2" threaded connection enables straightforward installation into standard fittings and radiators. Its automatic float mechanism vents air without manual intervention, ensuring stable system performance and helping to prevent air-related faults such as knocking, reduced flow or local overheating.

Suitable for

• Domestic and commercial radiators and convectors
• Manifolds and distribution headers in hydronic heating systems
• Hot and cold water pipeline branches where air accumulation is possible
• Retrofitting existing systems to improve venting and circulation

Key specifications

• Connection type: 1/2" threaded angled fitting
• Finish: chrome-plated surface
• Operation: automatic float-operated air release
• Typical application: closed heating and plumbing systems
• Installation position: angled / lateral mounting points

How to use

Install the angle air vent in the designated port of the radiator, manifold or pipeline branch using the 1/2" threaded connection; ensure proper sealing with suitable thread tape or sealant rated for heating systems. Position the vent so that the highest local air pocket migrates to the unit. The device operates automatically under normal system pressure and temperature: trapped air rises into the vent chamber, lifts the internal float and is expelled through the discharge port. Periodically inspect the vent for signs of leakage or blockage and replace if the automatic function is impaired.

Usage recommendations

Use compatible sealing materials and avoid excessive tightening to prevent thread damage. For best results, install vents at high points and at the end of branches where air tends to accumulate. If persistent air issues occur, check system balance, fill procedures and consider additional vents or professional servicing.
