## Long description

Purmo RS-MUFA 1/2 is a brass union fitting for radiator connection, designed for the M-2 radiator inlet. The fitting creates a secure mechanical link between a radiator valve or pipework and the radiator inlet using a 1/2" threaded connection. Manufactured from brass, the union fitting offers corrosion resistance and mechanical durability suitable for central heating installations and radiator replacement or retrofit tasks.
Advantages
The brass construction ensures long-term resistance to corrosion and wear in hot-water heating systems. Its 1/2" threaded interface provides compatibility with common radiator valves and piping standards, enabling straightforward mechanical connection without soldering. The compact union design facilitates disassembly and reassembly during maintenance or radiator replacement, minimizing the need to drain entire heating circuits.
Suitable for
 Connection of radiators to existing 1/2" valves and pipes
 Radiator replacement or retrofit projects in central heating systems
 Maintenance tasks requiring temporary disconnection of a radiator
 Installations where a durable, corrosion-resistant mechanical joint is required
Key specifications
 Material: brass for corrosion resistance and strength
 Connection type: 1/2" threaded union compatible with standard radiator inlet fittings
 Design: compact union fitting for mechanical join between valve/pipework and radiator inlet
 Application: hot-water central heating radiator connections and retrofit use
How to use
Fit the Purmo RS-MUFA 1/2 by threading the union onto the radiator inlet and tightening it to the corresponding 1/2" valve or pipe thread. Ensure sealing surfaces and any included gasket or sealing element are correctly positioned before final tightening. For installations under pressure, follow standard procedures for isolating and draining the section of the system when necessary, and torque connections to manufacturer-recommended levels to avoid leaks while preventing over-tightening that could damage threads.
Usage recommendations
Use appropriate sealing materials where required and verify compatibility with valve and pipe materials. During installation or maintenance, isolate and depressurize the heating circuit as needed and check for leaks after refilling and reheating the system.
