Product description
The F420 is the internal cartridge of a thermostatic radiator valve: the brass insert that actually shuts the water off. It lets a worn or damaged valve be repaired by replacing the cartridge instead of draining the whole circuit and cutting the valve out, which is why heating wholesalers and housing maintenance companies stock it.
Key features
- Repairs a valve without draining the system
- Brass insert with sealing rings
- White knob
Applications
Housing maintenance, valve repair and refurbishment programmes.
