Radiator Valve and Air Vent Set FERRO ZGG2B — 1x 1/2" Radiator Plug with Air Vent and Mounting Brackets

FERRO ZGG2B is a compact radiator accessory set that contains one 1/2" radiator plug with an integrated air vent and mounting brackets. Designed for use with central heating radiators, this set enables manual venting of trapped air, simple pressure management and secure attachment of the vent and plug. The components are suitable for routine maintenance and installation tasks in domestic heating systems where a single 1/2" connection and a manual air release are required.

Advantages

The set combines a 1/2" radiator plug and a manual air vent in a single kit, reducing the need to source parts separately. Mounting brackets are included to ensure stable and correct positioning of the vent and plug on the radiator body. The straightforward design allows manual bleeding of radiators without special tools and supports quick replacement during maintenance.

Suitable for

• Domestic central heating radiators with 1/2" connections
• Routine radiator maintenance and air bleeding
• Replacement of a damaged or leaking radiator plug or vent
• Installation tasks requiring secure mounting of venting components

Key specifications

• Contains: one 1/2" radiator plug with air vent and mounting brackets
• Connection size: 1/2"
• Function: manual air venting and radiator sealing
• Application: central heating radiators in domestic systems

How to use

Shut down the heating circuit and allow the radiator to cool before starting. Fit the 1/2" radiator plug into the radiator connection and secure the air vent with the supplied mounting brackets according to the radiator manufacturer’s recommended position. To bleed the radiator, open the vent slowly until trapped air is released and water begins to flow, then close the vent. Check the connection for leaks and, if necessary, tighten the plug lightly. Re-pressurise the system and verify correct operation.

Usage recommendations

Use this set only on compatible radiators with a 1/2" connection and follow standard safety procedures: isolate the heating system, vent carefully to avoid hot water contact, and verify system pressure after bleeding. For plumbing or heating systems with different connection sizes or integrated thermostatic valves, choose appropriate components or consult a heating specialist.
